    Description: This is the River Lynher Salmon Action Plan Final document produced by the Environment Agency in 1999. This final Salmon Action Plan (SAP) for the River Lynher catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Lynher salmon stock. The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The River Lynher salmon stock has suffered two periods of spawning target failure within the past ten years. This assessment can only be estimated and in this case is likely to be dependent on river flow and the availability of salmon to the rods as only rod catch is used in the compliance assessment.

    Description: This is the River Plym Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Plym catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Lynher salmon stock. These issues and actions follow on from the detailed analysis of the catchment, which is presented in the River Plym SAP Consultation document.The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The main objective of the River Plym SAP therefore, is to maintain, improve and develop the River Plym salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support. The River Plym has failed to pass its conservation limit since 1996, and the consultees felt very strongly that there were three major factors limiting the salmon stock of the River Plym.

    Description: This is the River Camel Salmon Action Plan produced by the Environment Agency in 2002. The report focuses on the River Camel Salmon Action Plan (SAP). The River Camel SAP follows the format of those completed for the Rivers Tamar, Lynher and Tavy. It is the 4th of 7 action plans that will be produced for salmon rivers managed by the Cornwall Area Fisheries, Recreation and Biodiversity Team. This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. In addition, for the first time, Salmon Action Plans have attempted to evaluate in economic terms, all of the contributory components of the salmon fishery. The River Camel Salmon Action Plan contains a description of the river catchment and highlights particular features that are relevant to the salmon population and associated fishery.

    Description: This is the River Fowey Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Fowey Salmon Action Plan (SAP). The River Fowey SAP follows the format of those completed for the Rivers Tamar, Lynher, Tavy and Camel. It is the 5th of 7 action plans that will be produced for salmon rivers managed by the Cornwall Area Fisheries, Recreation and Biodiversity Team. This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Fowey SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. Notably, there are historic workings for copper and china clay and two significant potable supply reservoirs (Siblyback and Colliford) which have been constructed within the catchment during the past 35 years. The whole of the Fowey catchment is set at the highest water quality grading of RE1 and this standard is met in all reaches of the River Fowey and its tributaries.

    Description: This is the River Tamar Salmon Action Plan Consultation document produced by the Environment Agency in 1998. The report pays attention on the external consultation of the River Tamar Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Tamar was one of the premier salmon rivers in the West Country, supporting fifteen licensed estuary nets, and the second highest rod catch behind the River Exe. The River Tamar SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery.

    Description: This is the Gunnislake Fish Counter, Annual Report 1999 produced by the Environment Agency South West Region on March 2000. The report presents the daily upstream counts of migratory salmonids recorded at Gunnislake Weir fish counting station (SX 435 713) situated on the River Tamar in 1999. The counter data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the implementation of the National Spring Salmon Byelaws. The fish counter at Gunnislake is a resistivity based system (Logie 2100A – Aquantic limited) and is installed in the fish pass on the Cornish bank of the River Tamar at the head of the tide. The minimum salmon count for 1999 was 2691. The run pattern observed for salmon and sea trout in 1999 was generally consistent with that of previous years. However, the total combined annual count of salmon and sea trout migrating upstream on the River Tamar in 1999 was 25% higher than the 5 year average (1994 - 1998).

    Description: This is the Restormel Fish Counter, Annual Report 2001 produced by the Environment Agency South West Region on March 2002. The report presents the daily upstream counts of migratory salmonids on the River Fowey at Restormel Weir fish counting station (SX 107 613) in 2001. The counter data covers the period of the commercial salmonid net buy back scheme and the national spring salmon byelaws. These reduce the commercial netting season for salmon and sea trout to between 16 June and 31 August. The fish counter at Restormel is installed on a crump sectioned weir on the River Fowey. The fish counter is a resistivity based system and operates over all three channels of the weir. 2001 was a good year for large sea trout. The number of returning large sea trout was above average in April, May, June and July and equal to or higher than the previous recorded maximum in those months. The main run of small sea trout occurred at a similar time to previous years with the highest numbers of fish entering the Fowey during June and July.

    Description: This is the Restormel Fish Counter, Annual Report 2007 produced by the Environment Agency South West Region on March 2008. The report presents the upstream counts of migratory salmonids recorded on the River Fowey at Restormel Weir fish counting station (SX 107 613) over the period March 2007 to February 2008 inclusive. Data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the National Spring Salmon Byelaws (2 March- 15 June). The minimum upstream salmon estimate for 2007, over the period July 2007 to February 2008, was 796, which is the fifth highest recorded count over the past 13 years. The number of returning salmon in 2007 suggests a downward trend in numbers since 2004. The 2007 large sea trout count is similar to 2006. Overall, the number of fish returning is still low in comparison with the 10-year average. There was a noticeable decrease in the number of small sea trout returning compared to 2006 and the 10-year average. The Fish counter at Restormel suffered several faults.

    Description: This is the Restormel Fish Counter, Annual Report 2006 produced by the Environment Agency South West Region on March 2007. The report presents the upstream counts of migratory salmonids recorded on the River Fowey at Restormel weir fish counting station (SX 107 613) over the period March 2006 to February 2007 inclusive. Data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the National Spring Salmon Byelaws (2 March- 15 June inclusive). The minimum upstream salmon estimate for 2005 (1046), over the period July 2005 to February 2006, was 20% lower than that recorded over the same period in 2004 (1301). However, this is the second highest count recorded over the past 11 years. The total sea trout count (10448) was 8% higher than 2004 (9608). The number of salmon and large sea trout was lower than average in 2005. However, the overall numbers of adult salmon and sea trout returning have been increasing year on year since 1997. This overall increase in the salmon and sea trout counts, together with the consistency of the numbers of fish returning over recent years suggests that measures designed to protect salmonid stocks in the River Fowey are working.

    Description: This is the River Fowey Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Fowey catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Fowey salmon stock. The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The main objective of the Fowey SAP therefore, is to maintain, improve and develop the Fowey salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support. Although the Fowey is passing its conservation limit, the consultees felt very strongly that there were two major factors limiting the salmon stock of the River Fowey- the overgrazing of Bodmin Moor and the use of the catchment for water supply by South West Water.

    Description: This is the River Lynher Salmon Action Plan Consultation document produced by the Environment Agency in 1998. The report pays attention on the external consultation of the River Lynher Salmon Action Plan (SAP). The River Lynher SAP follows that for the River Tamar and is the second of seven action plans that will be produced for salmon rivers managed by the Cornwall area fisheries department. This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Lynher SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The analysis of recent and historical catches of salmon on the River Lynher from both the rod and net fisheries indicated the fishery's reliance upon post 1 June salmon. Historically, annual salmon catches (both rod and net) on the River Lynher have been found to consist of a much higher proportion of pre 1 June (spring) salmon. Evidence is provided that illustrates the extent of the decline within this stock component since the early 1980s.

The report presents the daily upstream counts of migratory salmonids recorded at Restormel Weir counting station (SX 107 613) River Fowey in 1999. The counter data covers the period of the commercial migratory salmonid net buy-back scheme, which was in operation between March and June 1999. The fish counter is a resistivity based system (Logie 2100 A - Aquantic limited) and operates over all three channels of the weir at Restormel. The minimum salmon count estimate was 497, and the 1999 upstream count for sea trout was 6590. The run pattern observed for salmon and sea trout in 1999 was generally consistent with that of previous years. Flows on average were half those of 1998 during September, October, and November.

    Description: The stock of salmon in any river is largely dependent upon the escapement of sufficient fish to ensure that an adequate quantity of ova is deposited and full use is made of all suitable spawning areas. At the present time, no accurate information is available on the numbers of fish entering rivers. Therefore, catch returns provide valuable information on fish stocks.This report summarises the catch returns for salmon in the Lancashire River Authority in the North of England for the years 1960-1964. Rivers included are the Lune, Ribble, Kent, Leven and Duddon.

    Description: This is the River Plym Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Plym Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Plym SAP follows the format of those completed for the rivers Tamar, Lynher, Tavy, Camel and Fowey. It is the sixth of seven action plans that will be produced for salmon rivers managed by Cornwall Area. The River Plym SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. Notably, there are historic workings for china clay and a significant potable water supply at Burrator Reservoir. The main River Plym has been designated as River Ecosystem class 1 for its water quality objectives. This is the highest water quality target set for rivers. This standard has been met in all reaches of the main River Plym and River Meavy.

    Description: This is the River Yealm Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Yealm catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Yealm salmon stock. The actions presented within this Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. An attempt has been made to cost these actions, identify possible sources of funding and to provide a timescale for action. The main objective of the River Yealm SAP is to maintain, improve and develop the River Yealm salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support.

    Description: This is the Restormel Fish Counter, Annual Report 2005 produced by the Environment Agency South West Region on March 2006. The report presents the upstream counts of migratory salmonids recorded on the River Fowey at Restormel weir fish counting station (SX 107 613) over the period March 2005 to February 2006 inclusive. Data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the National Spring Salmon Byelaws (from 2 March to 15 June Inclusive). The minimum upstream salmon estimate for 2005 was 1046, this is the second highest count recorded over the past 11 years. The total sea trout count (10448) was 8% higher than 2004 (9608). This overall increase in the salmon and sea trout counts, together with the consistency of the numbers of fish returning over recent years suggests that measures designed to protect salmonid stocks in the River Fowey are working.

    Description: As a program supporting academic research that addresses recognized societal needs, theFlorida Sea Grant Program is developing a research theme area on estuaries to provide a uniquely academic product that will augment mission-oriented research undertaken by government and bythe private sector. This report is not a call for proposals. It does not prescribe a specific researchplan. Rather, it is a concept paper designed to focus research on two broad "organizing themes":(1) the hydrology of Florida's estuaries, and (2) the impact of cyclic environmental variability onestuarine function.

    Description: This is the first of a pair of reports documenting the effects of storms on barrier island systems.The present report (Volume 1) investigates storm effects on natural island conditions whereasVolume 2 addresses the effects of seawalls. With the aim of simulating the effects of overwashon barrier islands and characterizing their response, a series of nine experiments was conductedat the Coastal Engineering Laboratory of the University of Florida. The barrier island wassimulated by a 400 feet wide (prototype units) horizontal crest and an initially planar (1:19)beach. The effects of various storm surge levels and accompanying overtopping were investigated.Experiments were conducted with both regular and irregular storm waves. Regularwaves without overtopping caused the formation of a substantial berm in the swash zone and aprominent longshore bar offshore. Increasing degrees of overtopping resulted in substantial lossof sand from the barrier island system. The longshore bar was considerably more subtle for thehighest water level tested (11.5 ft. above mean sea level). Simulation of a storm-surge hydrographwith rising and falling water levels indicated that the presence of the bar tends to occuronly during a relatively steady or slowly changing water level. The experiments with irregularwaves were conducted with reasonably similar wave heights and carrier periods as those withregular waves. The major difference was in the characteristics of the longshore bar response. Incomparison with cases with regular waves, the bar was less distinct without overtopping, subtlewith minimal overtopping and absent in cases with substantial overtopping. These experimentsseem to indicate that offshore bars are simply break-point bars which require a fairly steadybreak-point and undertow (return of mass transport) for optimal formation.

    Description: This thesis examines the historical shoreline response to inlet modifications and sealevel rise. Inlet modifications are considered to be the geographic stabilization and training(through the use of structures) of natural inlets and the creation and further modification ofartificial inlets. Shoreline response to natural and artificial processes must be understood inorder to predict the performance of the coastline. The tendency for creating and modifyinginlets increases as industry and population growth demands. Sea level rise is a natural processwhich cannot be controlled at this time. Current theoretical approaches to predictingshoreline response indicate that sea level rise and inlet modifications can cause substantialshoreline impact. Florida, with roughly a century of shoreline position and relative sea leveldata, provides a basis for examining past trends and comparing them with theory.The shoreline of Florida was found to be accreting with the greatest accretion alongthe east coast. Shoreline responses within the boundaries of the erosional influence of inletsdue to their creation and/or modification were examined for 19 inlets around the coast ofFlorida. The differences in the shoreline response before and after the initial modification ofeach inlet show the erosional strain that inlets apply on the nearby shoreline. The effect onshoreline response due to the human intervention (unnatural processes) of modifying inletswas isolated and examined. The shoreline response due to this "human intervention" was erosional, thereby showing the negative impact that modified inlets have on shorelines. Thisinduced erosion is responsible for the loss of roughly 21.6 million cubic yards of sand from theshoreline that is within the erosional influence of Florida's east coast inlets. Combining theshoreline changes due only to natural processes with sea level rise data allows for comparisonwith the commonly accepted Bruun Rule for shoreline response as a result of a changingsea level. This comparison and the effects of including a lag time between a rise in sea leveland a change in shoreline along the east coast of Florida during the last century show noagreement with the Bruun Rule and no correlation with a specific lag time.

    Description: This is the second of a pair of reports documenting the effects of storms on beach systemsincluding the presence of seawalls. With the aim of simulating the effects of overwash onbarrier islands with seawalls and characterizing their response, a series of eight experimentswas conducted at the Coastal Engineering Laboratory of the University of Florida. The barrierisland was simulated by a 400 feet wide horizontal crest and an initially uniform mildly-sloped(1:19) beach. The effects of positioning the seawall at two different locations as well as the effectsof various storm surge levels and accompanying overtopping were investigated. Experimentswere conducted with both regular and irregular storm waves. With the seawall located at theslope break between the crest and the sloping beach of the barrier island, and the crest of theseawall just submerged in sand, the effects on the sediment transport process were found to beminimal. For the same position of the seawall but with the crest of the seawall raised above thesurrounding ground level, overtopping caused washover of sand indicating substantial transportin suspension. Increased levels of overtopping tended to accentuate bed profile changes butsupress bar formation (as did irregular waves). Positioning the seawall at the Mean Sea Levelshoreline caused significant scour both immediately landward as well as immediately seawardof the seawall. A prominent scour trough developed further seaward. The longshore bar washighly three-dimensional. It appears that seawalls need to be located adequately landward of theshoreline to discharge their function effectively without adverse effect to the beach. In addition,concerns for safety warrant the presence of an adequate buffer-zone between the seawall andthe upland property. (61 pp.)

    Description: The value of the natural resources of the White River Basin (Basin), AR isrecognized by the area's designation as a "Wetland of International Importance". TheBasin constitutes one of the Nation's largest remaining intact forested wetlandlandscapes, second only to the Atchafalya Basin. It supports the North Americancontinent's largest concentration of over-wintering mallard ducks, a world-class troutfishery, the last vestige of a big river fishery remaining in the Mississippi River Basin,and numerous threatened and endangered species. The continued viability of thiswetland ecosystem depends on the suitability of the hydrologic environment to theresident flora and fauna. Numerous modifications of the Basin hydrologic features in thepast century have seriously impaired the sustainability of these resources. The Basinwidealterations of hydrologic processes (e.g., impoundment and regulatory releases offlows and volumes in the upper reaches, navigational modifications of lower reaches, andconsumptive demands for agricultural use throughout) have affected the hydrology of thesystem profoundly. The result is highly regulated flows and stages, vastly alteredhydrologic patterns, over-stabilized water levels, and disruption of seasonal waterdistribution patterns. Given the critical nature of hydrology in regulating the structureand function of wetland ecosystems, the impacts have been devastating, particularly tothe critical bottomland hardwoods that support the Basin's fish and wildlife resources.To date these piece-meal, system-wide, hydrologic alterations have cornmutativelydegraded the habitat value of this resource for fish and wildlife in the Basin, and havelead to changes in their numbers and distributions. In spite of the enormous stakesinvolved, there has been no comprehensive characterization of the Basin hydrology.System alterations such as channel deepening, dam construction, water allocationplans, and flood control measures are currently pending. These projects will potentiallyhrther modify the hydrologic environments of the Basin, and no doubt require mitigationmeasures. In addition, there is genuine interest in restoring aspects of the Basin's historichydrologic regime within some set of reasonable limits. In order to proceed with thiseffort, the anticipated effects of these modifications and restorations on the Basin ecologyrequire thorough study of the area's historic hydrology, so that connectivity among Basinprecipitation patterns, flow fluctuations, and land use changes can be made. A basinhydrologic characterization is an initial component of this effort. The focus of this effortwas to determine and assemble the data set from which characterization of the hydrologicenvironments of the Basin using historic and recent water level, flow, (primarily byUSGS-WRD) at locations throughout the Basin could proceed.

    Description: Loxahatchee can be grouped into three zones according to the patterns of change of treeislands observed from 1950 to 1991. 1 ) the edge ofthe refuge adjacent to the canals, 2) the eastern interiorof the refuge, and 3) the western interior ofthe refuge. The general trend is for tree islandsAlong the edge of the refuge to have decreased insize, number, and percent cover, while those on theinterior increased in size, nunber, and percentcover.Results from this study illustrate the importanceof flow magnitude as well as hydroperiodand depth in stucturing patterns of tree islandswithin this peat wetland. Restoration of historichydroperiods and depths without historic flow patternsmay not be sufficient to restore or maintainthe historic pattern and function of the system. (60 pages)

    Description: We present a new modeling method for use in large-scale physical systems, such as the Everglades ecosystem.The current work that has been done in the ATLSS (Across-Trophic-Level System Simulation) project-whichfocuses on simulating key Everglades system components-relies on code integration. While this represents anecessary first step in analyzing the dynamics of species within the Everglades, it falls short of true modelintegration. We have constructed a methodology called object-oriented physical modeling (OOPM), which allowsa comprehensive knowledge representation to be constructedfor large-scale systems. OOPM enforces theidea that an implementation ofcomputer code can be accomplished in an incremental fashion by starting with aconceptual model and progressing to more detailed models. During this evolutionary procedure, a minimal amountof code is written, since the emphasis is on developing the conceptual model so that it not only represents theintuitive aspects ofthe model, but is also executable. OOPM provides a kind of "blueprint" for ecologists, biologistsand hydrologists to communicate and integrate models effectively. (14 page document)

    Description: Work has begun on studying the factors responsible for productivityin the Florida springs, which are nearly constant temperature, constantchemical, steady state giant laboratories. Progress has been made on fiveaspects: qualitative description, quantitative description, completionof knowledge of chemical factors, measurement of productivity , developmentof productivity theory.Measurement of the primary productivity in Silver Springs and GreenCove Springs by two new methods: the raising of organisms in cages, and themeasurement of night & day differences in oxygen downstream agree roughly.Production in these springs is greater than previous production figures reportedfor marine, fresh water, and land areas. Instantaneous measures of production show large variations with season, time of day, cloud cover. Productionestimates range from 11,000 lbs per acre per year to 70,000 lbs. glucose peracre per year during daylight hours.Essential stability of the springs environment has been shown withrespect to temperature, phosphorus, and plant cover. A correlation of speciesnumber with lack of stability has been shown with insects. Quantitativestudies have shown very large plant base to pyramids of mass. Correlationof marine invasion with chlorinity has been shown. The essential aspects ofpH regulated phosphorus geochemistry in Florida have been outlined. Sometheoretical ideas on productivity have been evolved. Mapping of sessileorganisms in springs and taxonomic identification of dominants are halfcompleted. Plans for second six months include measurement of herbivoreand carnivore production rates and completion of food chain efficiencydeterminations in Silver Springs as a preparation for subsequentcomparisons between springs.

    Description: The effect of productivity on species variety has been studied by countsof diatom species on glass slides at favorable and unfavorable stations withinSilver Springs. Species variety has been presented in a measure that is independentof sample size, "species per cycle". This measure is based on the linear increase of accumulated species with logarithmic increase of individuals counted, which has been found approximately true for many kinds of populations in many communities. Diatom productivity was measured by the rate of chlorophyll accumulation. The poor station accumulated diatoms and chlorophyll slowly and was characterized by a large species variety. There was little change after 79 days. The rich station accumulated diatoms and chlorophyll rapidly and was characterized by a small species variety that decreased for 93 days as the density of the population increased. These results indicated that species variet was decreased by conditions of high productivity possibly through the action of high densities and competition.Twelve new diurnal production curves were obtained including two more on Silver Springs and one each for 10 different Florida Springs. A shallow oligohaline spring possessed the highest productivity of 58.0 gm/m2/day; a shaded and anerobic spring possessed the lowest producvitiy of 0.66 gm /m2/day. Findings in further studies in Silver Springs indicated a two fold diurnal chlorophyll fluctuation in the pseudoplankton going downstream, photosynthetic quotients corresponding to carbohydrate production on winter or heavily clouded days, and higher quotients corresponding to protein production on sunny, summer days; evidences that bell jar estimates of respiration in flowing water communities lead to underestimates; recalculation of mean depth of plant beds leads to a 5% estimate of photosynthetic efficiency for Silver Springs (rather than 8%). Correlated with a 20% decrease in the discharge associated with widespread drought in 1954-55 the oxygen of the main boil dropped from 2.5 ppm to 1.7 ppm. A production measurement by the diurnal oxygen and carbon-dioxide curve method was made in a somewhat isolated "boat basin." Efficiency of production in this stationary, plankton containing water of Silver Springs origin was about 1%. Further evidence was obtained of nitrate increase in water flowing from anaerobic springs over blue-green algae. The area based chlorophyll of the benthic Silver Springs community was similar to that in forests and lakes of Europe. (63 pages)

    Description: The critical need to predict the turbidity in water due to fine-grained sediment suspensionunder wave action over mud deposits for sedimentation and erosion studies, as well assorbed contaminant transport, is well known. Since fall velocities of fine sediment particlesare very small, they can be easily transported by hydrodynamic flows such as waves andcurrents. The presence of these particles in the water column affects accoustic transmission,heat absorption and depth of the eutrophic zone (Luettich et al., 1989). Because these sedimentsalso have a strong affinity for sorbing nutrients and toxic chemicals, sediments whichhave been deposited on the bottom may function as a source of contaminants to the watercolumn if they are disturbed by eroding forces resulting, for instance, from wave action. Anoutstanding example of a water body for these problems is Lake Okeechobee, the largestshallow lake in Florida. This lake shows typical signs of artificial eutrophication mainly dueto increased phosphorus loading associated with the surrounding region. Resuspension of sediment at the bottom of Lake Okeechobee composed of fine-grainedmaterial has been examined. A sediment transport model was used to simulate likelytrends in the evolution of the vertical suspended sediment concentration profile resultingfrom wave action, and the corresponding eroded bed depth was calculated through massbalance. Requisite information on characteristic parameters and relationships related tofine sediment erodibility were derived from field sampling of bottom sediment in the lake,and through laboratory experiments using this sediment and lake water.

    Description: This report is to document the programs my colleague and I developed for computingtime-dependent nearshore hydrographic changes including beach profile responses.The time scale of the model is suitable for storm events to seasonalchanges, currently up to one year period. The model is very stable and is capableof handling complicated topographies including inlets and irregularly-shapedstructures such as curved jetties and breakwaters.The purpose of three-dimensional models is to predict the change of bottomtopography from the spatial distribution of the sediment transport rates, which areevaluated from the nearshore wave and current fields computed point by point insmall areas defined by a horizontal grid placed over the region of interest. Modelsof 3-D beach topography change require much fewer idealizations than do the linemodels. (Document has 43 pages.)

    Description: The Cabo Rojo Salt Flats, at the southwestern tip ofPuerto Rico, provide important autumn stopover and winteringhabitat for migratory shorebirds. I studied the abundanceand distribution of shorebirds and their food resources atthis site during autumn of 1990 and 1991.Small calidrids (primarily Calidris pusilla and C.mauri) were the most abundant shorebirds at the salt flats.The maximum weekly counts of small calidrids in 1990 (2,690)and 1991 (3,532) occurred in mid October. Calidrids foragedprimarily in the Fraternidad lagoon system; roosting tookplace most often at the neighboring Candelaria Lagoon.The macroinvertebrate prey important to calidrids in theFraternidad system were Dasyhelea (Diptera), Trichocorixa(Hemiptera), and Artemia (Anostraca). Changes in invertebrateabundance coincided with fluctuations in salinity. (100 page document)

    Description: This report documents breeding numbers, reproductive success, and foragingdispersion of long-legged wading birds in the Water Conservation Areas (WCAs) of theEverglades during the first six months of 1993. Briefly, the 1993 spring had abnormallyhigh water and windy conditions throughout the season, and produced poor nesting effort,low to moderate nesting success, and low production of young. Some species, like WoodStorks and White Ibises, did not nest at all in the WCAs. Others, like Great Egrets andTricolored Herons, showed considerably tenacity under the extremely poor nestingconditions. The 1993 season provided a rare chance to record the reproductive responses ofwading birds during sustained high water conditions. (108 page document)

The monitoring of nesting has beenaccomplished bystandardized systematic aerial and ground surveys and study of nestingsuccess of nesting colonies in Water Conservation Areas (WCAs) 2 and 3 ofthe centralEverglades. The White Ibis work was accomplished through 1) investigation of thenutritional, behavioral, and hormonal aspects of "normal" breeding in a captive colony ofScarlet Ibises (Eudocimus ruber, considered by many to be the same species as the WhiteIbis), and 2) documenting the physiology, nutritional state, breeding phenology,contaminant load, and hormonal status of free- living adult White Ibises in the centralEverglades.

    Description: Eglin AFB on Cape San Blas consists of approximately 250 acres located about180 miles east of the main Eglin reservation. This area lies on the S1. Joseph peninsula,part of a dynamic barrier island chain that extends across the northern Gulf of Mexico.Due to the natural forces that formed Cape San Blas and those that maintain this area, St.Joseph Peninsula has experienced severe land form change over time (see GIS land formchange maps). These changes allow for fluctuations in habitat types along Cape San Blas(see GIS land cover change maps)that influence the floral and faunal species using thisarea.The dynamic environment along Cape San Blasincludes flatwoods, interdunalswale, rosemary scrub, and beachfront. These habitats support a wide array of species,including several threatened and endangered species such as the loggerhead sea turtle(Caretta caretta), PipingPlover (Charadnus melodus), Least Tern (Sterna antillarum),and Bald Eagle (Haliaeetus leucocephalus). Proper management of these species and theirhabitats require knowledge of their abundance and distribution, and the effectsdisturbances have on their survival.In addition to threatened and endangered flora and fauna, Cape San Blas alsosupports tourists and recreationists. Although Gulf County is sparsely populated, withapproximately 13,000 inhabitants throughout 578 square miles, summer tourism and heavyrecreational use of beaches for fishing, crabbing, and shelling place continued andincreasing pressure on the natural resources of these areas (Rupert 1991). Gulf County isalso one of the few remaining counties in Florida that permits vehicular traffic on itsbeaches, including Cape San Blas. In addition to recreational use of these habitats;EAFBalso uses the area for military missions. Air Force property on Cape San Blas is primarilyused for radar tracking of flying missions over the Gulf of Mexico, although in recentyears it has been used for missile launchings and other various military activities.To allow continued military and public use of Air Force property while alsoprotecting the unique flora and fauna of the area,EAFB proposed a characterization of theresources found along Cape San Blas. A complete inventory of the physical features of thearea included investigating topography, soil chemistry, hydrology, archeology, and thedynamics of land mass and land cover change over time. Various thematic layers within ageographic information system (GIS) were used to spatially portray georeferenced data.Large scale changes over time were assessed using stereo aerial photography. Vegetationtransects, soil samples, elevation transects, an archeological survey, freshwater wells, anda tidal monitor were used to investigate the remaining features. (247 page document)

    Description: The Suwannee River sill was constructed following extensive wildfires during1954-1955, with the intent of protecting the swamp and surrounding uplands from effectsof wildfires. During subsequent years, concern was raised that the dam might beadversely affecting the swamp ecology by extending periods of inundation, increasingwater depths, and subsequently affecting swamp vegetation. Delineating the effects ofthe Suwannee River sill on the swamp hydrologic environment and vegetationdistributions, in the process of exploring relationships among driving functions andlandscape responses, was a purpose of this research.(834 page document)

    Description: The objectives of this study were 1) to determine the maximum structure-inducedlocal sediment scour depths for the proposed bridge piers for the Merrill BarberBridge over Indian River on.State Road 60 in Indian River County, Florida and 2) todetermine the feasibility of predicting equilibrium local scour depths near complexmultiple pile bridge piers from bottom shear stresses on the prescoured bed. Aseries of hydrodynamic tests were conducted in a laboratory flume (100 ft long x 8 ftwide x 2 ft deep) where flow velocities near model piers were measured with a twocomponent constant temperature anemometer at a height of 3 mm above the bed. Bottomshear stresses were then estimated from the flow measurements. The piers (which are1/15 scale models of proposed Merrill Barber Bridge piers) consisted of thirtysixsquare piles (3 columns of 12) and a pile cap that was positioned at differentelevations above the bottom. Two different pile cap shapes were also considered. Asimple relationship between the prescoured bottom shear stress and the equilibriumlocal scour depth was postulated.Sediment scour tests were then conducted in the same flume with the samemodels. The average duration of these tests was 28 hours. Scour depths weremeasured periodically throughout these tests using an acoustic transponder. Thescour measurements were used 1) to establish the maximum scour depths for the MerrillBarber Bridge piers and 2) to calibrate and test the scour-shear stress relationship.Even though the range of conditions tested was somewhat limited, the approach appearspromising and should be pursued further. A number of interesting findings were maderegarding the rate at which scour occurs in these complex structures. (Document contains 134 pages.)

    Description: This report presents the results of laboratory studies which were carried out in the Coastaland Oceanographical Engineering Laboratory to investigate the effects of ground water tableelevations on the beach profile changes over the swash zone. The experiment was conducted atthree different water table levels while the other experimental conditions were fixed to constantvalues with regular waves. The water table levels included (1) normal water table level whichis the same as mean sea level, (2) a higher level and (3) a lower level than the mean sealevel. Special attention was given to the higher water level to investigate whether this levelenhances erosion of the beach face and also to methods of interpreting the experimental data.The experiment described herein was carried out with a fairly fine sand and has demonstratedthe significance of beach water table on profile dynamics. The increased water table levelcaused distinct effects in three definite zones. First, erosion occurred at the base of the beachface and the sand eroded was carried up and deposited on the upper portion of the beachface. Secondly, the bar trough deepened considerably and rapidly and the eroded sand wasdeposited immediately landward. This depositional area changed from mildly erosional tostrongly depositional. Third, the area seaward of the bar eroded with a substantial deepening.The lowered water table appeared to result in a much more stable beach and the resultingeffects were much less. The only noticeable trend was a limited deposition in the scour area atthe base of the beach face. (Document has 37 pages.)

    Description: To predict the hydrodynamics of lakes, estuaries and shallow seas, a two 'dimensionalnumerical model is developed using the method of fractional steps. Thegoverning equations, i.e., the vertically integrated Navier-Stokes equations of fluidmotion, are solved through three steps: advection, diffusion and propagation. Thecharacteristics method is used to solve the advection, the alternating direction implicitmethod is applied to compute the diffusion, and the conjugate gradient iterativemethod is employed to calculate the propagation. Two ways to simulatethe moving boundary problem are studied. The first method is based on the weirformulation. The second method is based on the assumption that a thin water layerexists over the entire dry region at all times. A number of analytical solutions areused to validate the model. The model is also applied to simulate the wind drivencirculation in Lake Okeechobee, Florida.(135 page document)

    Description: Production measurements at different times of the year indicate a linear relationship of light intensity and overall production at about 8% of the visible light energy reaching plant level. Measurements of a coral reef at Eniwetok indicate 6%. Further evidence of breeding at all seasons but with a quantitative pulse in the seasons of maximum light indicates that the seasonal fluctuation in primary production is routed through reproduction rather than through major changes in populations. The succession of plants and anmals of the aufwuchs has been shown with glass slides and counts from Sagittaria blades. Losss of oxygen bubbles during the day and emergence of aquatic insects at night have been measured with funnels. Bell jar measurements are reported for bacterial metabolism on mud surfaces. pH determined CO2 uptake agrees with titration determinations. A few rough estimates of herbivore production have been made from caged snails, aufwuchs succession, and fish tagging. Nitrate uptake a night by aufwuchs communities has been confirmed in a circulating microcosm experiment as well as in bell jars in the springs. Distributions of oxygen and organisms have been used to criticize the saprobe stream classification system. Theoretical consideration of maximum photosynthetic rates in teh literature data indicates logarithmic rate variation inversely with organismal size just as for respiratory metabolism. Extreme pyramid shapes are thus shown for communities in which organismal size decreases up the food chain and for other communities with the same energy influx but with organismal size increasing up the food chain. Literature data is used to further demonstrate the validity of the optimum efficiency-maximum power principle for photosynthesis. Work on plants by Dr. Delle Natelson indicates essential stability of aquatic plant communities after 3 years and about 10-20% reproducibility in previous biomass estimates by Davis. Work on an animal picture of the fishery characteristics by Caldwell, Barry, and Odum is half completed. The study of aquatic insects in relationship to spring gradients by W.C. Sloan has been completed an an M.S. thesis. J. Yount has begun a study of affect of total productivity on community composition using aufwuchs organisms on glass slides placed in different current and light conditions in Silver Springs. (49pp.)

    Description: The mechanism by which fluid mud is formed by water wave motion over coastal andestuarine cohesive soil beds is of evident interest in understanding and interpreting themicrofabric of flow-deposited fine sediments in shallow waters, and hence the erodibilityof muddy beds due to hydrodynamic forcing. This study investigated water wave-inducedfluidization of cohesive soil beds composed of a 50/50 (by weight) mixture of a commercialattapulgite and a kaolinite in a laboratory flume. Temporal and spatial changes of theeffective stress were measured during the course of wave action, and from these changesthe bed fluidization rate was calculated. A previously developed hydrodynamic wave-mudinteraction model of the two-layered water-mud system was employed to study the natureand the degree of wave dissipation, in terms of energy dissipation rate, during the bed fluidizationprocess. By evaluating the mud rheological properties separately, a mud viscositymodel was developed, which was then used in conjunction with the wave-mud interactionmodel to obtain an effective sheared thickness of the bed resulting from wave action. Thisthickness, considered to be a representative of the fluidized mud thickness, was comparedwith the latter obtained from pressure measurements. Also, through this wave-mud modelthe relationship between the rate of fluidization and the rate of wave energy dissipationduring fluidization was examined. In general, for a given wave frequency, a larger wave fluidized the bed at a faster rateand to a greater depth than a smaller one. Furthermore, increased bed consolidation timedecreased the rate of fluidization due to increased mud rigidity. The rate of bed fluidizationwas typically greater at the beginning of wave action and decreased with time. Eventuallythis rate approached zero, while in some cases the wave energy dissipation rate approached aconstant value, which increased with wave height. As the fluidization rate approached zero,there appeared to occur an equilibrium value of the bed elevation, and hence a fluid mudthickness, for a given wave condition. During the fluidization process the bed apparentlylost its structural integrity by loss of the effective stress through a build-up of the excesspore water pressure. After wave action ceased, the bed structure exhibited recovery bydissipation of the excess pore water pressure.Further studies will be required in which the hydrodynamic model must be improved viaa more realistic description of mud rheology and relaxation of the shallow water assumption,and better pressure data must be obtained than in the present study. Nevertheless, thisinvestigation has been instructive in demonstrating relationships between the degree of mudfluidization, wave energy dissipation and bed consolidation time, and thus offers insight intoan important mechanism by which coastal and estuarine muds are eroded by wave action.

    Description: The West Indian manatee's metabolic physiology constrains it to subtropical and tropicalregions. In waters of the United States, a manatee's ability to find reliable warm-water refugiaduring winter cold periods is critical to its survival. This report documents how radio-taggedmanatees used a network of 14 industrial and 3 "natural" warm-water sites along the east coastof Florida and Georgia duringwinter. Most industrial sites were powerplant discharges but alsoincluded pulp mill effluents. TheU. S. Geological Survey's SireniaProject tracked 71 manateesover 12 winter seasons (1986-1998) using field-based VHF radio-telemetry and Argos satellite based telemetry.Thirty-seven individuals weretracked over periodsofat least 100daysbetween November and March of a given winter, manyfor multiple years. Presence at a warmwaterrefugewasdefinedas a location occurring within 200m (for a VHF field observation) orwithin 1 km (for a satellite-determined location) ofthe site. (133 page document)

    Description: The South Florida Ecosystem encompasses an area of approximately 28,000 km2 comprising at least 11major physiographic provinces, including the Kissimmee River Valley, Lake Okeechobee, the Immokalee Rise, theBig Cypress, the Everglades, Florida Bay, the Atlantic Coastal Ridge, Biscayne Bay, the Florida Keys, the FloridaReef Tract, and nearshore coastal waters. South Florida is a heterogeneous system of wetlands, uplands, coastalareas, and marine areas, dominated by the watersheds of the Kissimmee River, Lake Okeechobee, and theEverglades.Prior to drainage, wetlands dominated the ecosystem, covering most of central and southern Florida. Thelandscapes included swamp forests; sawgrass plains; mosaics of sawgrass, tree islands, and ponds; marl-formingprairies dominated by periphyton; wet prairies dominated by Eleocharis and Nymphaea; freshwater marshes;saltwater marshes; cypress strands; and a vast lake-river system draining into Lake Okeechobee. Elevated areasthat did not flood supported pine flatwoods, pine rocklands, scrub, tropical hardwood hammocks, and xerichammocks dominated by oaks. The natural seascapes of South Florida consisted of riverine and fringe mangroveforests; beaches and dunes; seagrass beds; intertidal flats; mud banks; hardbottom communities; coral reefs; andopen, inshore shallows. All these habitats were interconnected on an extremely low topographic gradient (2.8cm/km) with elevations ranging from about 6 m at Lake Okeechobee to below sea level at Florida Bay.The Science SUb-Group (1993) described the defining characteristics of the South Florida Ecosystem and the problems that resulted from hydrologic alterations and other anthropogenic changes.Restoration objectives were proposed for each sub-regionand the region as a whole.The overall goal of the restoration effort is to restore a sustainable South Florida Ecosystem that preservesthe valued properties of South Florida's natural systems and supports productive agriculture-, fishery-, and tourist.based economies and a high quality of urban life. Sustainability means high natural productivity, human andecosystem health, and resiliency to climatic extremes and catastrophic events. It also means accommodation ofneeds of human systems-flood control, irrigation, and drinking water supply.SCOPEThis section addresses the entire ecosystem, cutting across the artificial boundaries of designatedsubregions, as well as geopolitical and geomorphological boundaries, to present the broader issues of deVelopingan interagency and interdisciplinary ecosystem-based science program to support South Florida restoration. Herewe discuss the general premise and the general approach, with brief discussions on monitoring, modeling, andspecial studies. The latter two topics are covered in greater detail in other sections.

    Description: Following a large scale fish mortality caused by a considerable spillage of a pentachlbrophenol-based disinfectant from a mushroom farm, a biological survey of the river Conder was undertaken on 23.7.79. A spillage of this same make of disinfectant from this mushroom farm in February 1976 caused a similar large scale fish mortality.On that occasion, the pollution appeared to have little effect on the benthic invertebrates of the river Conder, with no dead organisms found, although the smallbeck which received the spillage was quite badly affected. This recent spillage of disinfectant involved a considerably greater volume (approximately 900gallons) than the 1976 discharge and so this report looks at whether invertebrate fauna of the main river were affected on this occasion. Kick samples were taken at a number of sites in the river Conder from the confluence with the polluted beck to Conder Green. A control sample was also taken upstream of the confluence with the polluted beck. All samples were examined on site and live and dead invertebrates noted and identified as accurately as possible.

    Description: The River Darwen is a highly impacted Lancashire river with very little known about its fishery interest above the impassable weir at Salmesbury Bottoms. Below the weir there are populations of coarse fish around the confluence with the River Ribble. To the knowledge of local bailiff staff, prior to 1996 the fish population in the middle and upper River Darwen had never been surveyed by electric fishing. In order to address this lack of knowledge, a survey was undertaken during the summer of 1996 with the aim of evaluating the salmonid and cyprinid fish population in the river. Twenty two sites were surveyed by electric fishing between June 11th and July 11th 1996. Information was gathered on the presence and density of fish populations in the river catchment, and analysed according to the National Fisheries Classification Scheme in order to determine how these populations compare nationally with sites of similar habitat features. From this report, recommendations were made to improve and develop the fishery potential in relation to water quality and habitat prioritising areas classed as being Ashless. It was recommended that juvenile coarse fish should be stocked in the Houghton Bottoms area. This area has excellent fishery habitat and was found to contain a minor coarse fish population. Water quality in this stretch of river was thought to be good enough to establish a major coarse fish population. Fish were introduced for the first time in 1998 at Houghton Bottoms from the Agency's Leyland Fish Farm. 3000 each of Roach, Chub and Dace were introduced. Further fish introductions occurred in 2000 with the stocking of 1000 Chub, again from the Agency's Leyland Fish Farm in the Lower Darwen and Witton areas of the main river on a trial basis.

    Description: The aim of this study was to assess the status of the juvenile salmonid and coarse fish populations of the Wyre catchment. Emphasis was placed on an examination of the distribution of spawning and nursery areas for salmonids within the study area and an assessment of the status of juvenile salmonid stocks. The species distribution and spawning areas for other fish species were also identified where possible and the status of the Wyre coarse fishery, downstream of Churchtown Weir, assessed. This report examines the results of stock assessment surveys carried out in the Wyre catchment between 2/06/92 and 11/08/92. Forty-six sites were surveyed from Tarnbrook Wyre (SD. 598577) and Marshaw Wyre (SD. 614541) downstream to St Michaels (SD. 465411). Flow, habitat and in-river obstructions have been shown to affect juvenile salmonid densities. A habitat description is provided for each site studied during the course of this study.

    Description: The aim of this study was to assess the suitability of Foxhouses and Grizedale Becks as nursery habitat for juvenile salmon. A comprehensive fish stock assessment survey of the Wyre catchment was carried out by the NRA in 1992. This survey found that juvenile salmon were absent from two sites studied in Foxhouses Beck. In one site in Grizedale Beck, 0+ salmon were found at very low densities. Juvenile trout were found in all three sites studied in 1992. On the basis of the results of the 1992 survey, these two becks were stocked in 1994 with 0+ salmon reared from Lune broodstock at the NRA's Witcherwell Hatchery. These salmon were stocked at a known density, following a pre-stocking survey. This report examines and compares the results of the pre-stocking survey consisting of fourteen sites in the two becks, carried out between 12/04/94 and 27/04/94 and a post-stocking survey of six sites, carried out between 12/10/94 and 19/10/94. Flow, habitat and in-river obstructions have been shown to affect juvenile salmonid densities. A habitat description is provided for each site surveyed during the course of this study.

    Description: Swanside Beck is formed from a number of minor tributaries which rise in the Middop area to the west of Barnoldswick. The Beck is approximately 10 km long from the source of its longest tributary (SD. 850445) to the confluence with the River Ribble (SD. 769455). Swanside Beck has one major tributary, Ings Beck, which rises from a number of sources on Twiston Moor and is approximately 6km in length from the source of its longest tributary (SD. 812418) to the confluence with Swanside Beck (SD. 785453). Both Swanside and Ings Becks are important spawning and nursery areas for salmon and sea trout from the River Ribble. In recent years a perceived decline in the migratory fish population of the becks has been reported. This decline has been reported in terms of both adult returns and juvenile production and has been particularly noted in Swanside Beck. The aim of this survey was to assess the likely benefits to Fisheries and Conservation interests of the adoption of a set aside policy for agricultural land adjacent to Swanside Beck. The survey also formed part of an on-going Fisheries study of factors limiting juvenile migratory salmonid production in Swanside Beck. This section of the report deals with the Fisheries aspects of the survey.

    Description: In October 1992, a fish population survey of the Swanside Beck system revealed that the densities of juvenile salmon present in the beck were generally poor. The survey highlighted that a potential reason for this may be due to a lack of spawning substrate resulting from siltation. Numerous workers have found that increased levels of A salmonid egg box experiment of Swanside Beck carried out in the spring of 1994, revealed that the survival rates in the majority of sites were good. While the in-site variability was relatively high, mean survival rates remained in excess of 70%. As a result egg survival rates were eliminated as the reason for low juvenile salmonid production. The only site with a relatively low survival rate was Swanside Beck downstream of Cowgill Beck. However, even at this site siltation was eliminated as the cause of the increased mortality rate. It is recommended that a salmonid stocking of Swanside Beck should be carried out this year. This should be followed by an electric fishing survey to evaluate juvenile salmonid survival rates.

    Description: An extensive survey of the River Lune using River Habitat Survey (RHS) was commissioned to assess the habitat quality of the Lune for salmonid fish. The main river on the Lune and tributaries were divided into 500m sections. A sample of 103 sections (25% of the total classified length) was randomly selected and surveyed in February/March 99. A Habitat Modification Score (HMS) describing the level of habitat modification was derived for each site and compared to the whole reference network and to rivers of similar types in Britain.The analysis of Habitat Modification scores show that more than 70% of the sites on the catchment are predominantly unmodified and very few sites are significantly modified (less than 10% of the sites). The analyses of the data collected suggest that although river habitats are altogether of good quality, the natural processes within the catchment may reduce spawning habitats for salmonids. The river processes appear to be driven by natural forces, although land-use is likely to impact on the levels of run-off. Further analyses using fisheries data on the Lune will investigate the relationship between the major environmental dimensions and fish distribution on the catchment.

    Description: The River Douglas has a long industrial heritage beginning in the early 18th century with its use by boats carrying goods between Wigan and Tarleton. The River and its tributaries have also historically been, and to a certain extent are still, subject to polluting inputs from the urban, agricultural and industrialised areas located within its catchment. During the early stages in the production of the River Douglas Catchment Management Plan, it became apparent that very little data existed on the populations of coarse and salmonid fish species within the River Douglas system. The data that did exist was largely anecdotal, consisting of catch reports from anglers or water bailiffs, or of dead and distressed fish following pollution incidents. This study was initiated to assess the status of coarse and salmonid fish species within the River Douglas system and so address the lack of knowledge. Eighty two sites were surveyed by electric fishing, including 14 sites using an electric fishing punt and up to four anodes. The data was analysed according to a new National Fisheries Classification Scheme. This classified the sites by the fish stock s present and compared the results with a database containing information from sites around the country that have similar habitat types. A stocking experiment was also undertaken in the River Lostock using chub reared at the Leyland Hatchery. These were marked with an identifiable blue spot in the spring of 1995 and then released into three, previously surveyed, locations in the river. These sites were then resurveyed during the summer stock assessment. This report also Site Reports with details on monitored sites, habitat features and fishery classification.

    Description: The angling season for non-migratory brown trout, in the Environment Agency (EA) North West Region, runs from March 15th to September 30th. Each year, large numbers of farm reared brown trout are stocked into the rivers of the North West Region's Central Area. In 1994, approximately 20,000 brown trout were introduced into the River systems of the Lune, Wyre and Ribble by local angling clubs and fishery owners. Most of these fish were stocked at a length greater than that defined by local byelaws as the takeable size (200mm). Introductions are made to supplement the existing wild brown trout populations within the river and increase the probability of an angler catching a fish. Stocking with fish of a sufficient length allows the successful angler to remove the catch for their own use. In this way, stretches of the rivers are effectively managed as "put and take" fisheries for brown trout. A number of brown trout fingerlings are also introduced each year by angling clubs and fishery owners. These are stocked with the expectation that the fish will survive in the river to grow, over-winter, and eventually attain a takable size with an increased degree of "wildness". The lower cost of fingerlings, as opposed to trout of a takable length, makes their introduction more attractive to angling clubs since a greater number can be stocked for a given cost. Although the practise of stocking brown trout has occurred for many years in the Central Area, there is little information of its success in terms of increasing anglers catches, or the survival offish introduced. This study was initiated to determine the recapture rates by angling of brown trout following their introduction into a river fishery. The information gained from this study can then be used to give guidance to angling clubs and fishery owners on the optimal strategies for stocking fish.

    Description: The River Ribble bailiff team completed a total of 377 salmonid creel censuses by interviewing anglers fishing on the banks of the Rivers Ribble and Hodder during 1994. The study was undertaken for a number of reasons: (i) , To determine which areas of the river were fished by anglers. (ii) To ascertain which fishing methods were used in these areas. (iii) To identify the success of each fishing method within each area of the River Ribble system. In a limited 1993 sampling programme, 55 censuses were carried out. Results from these indicated that fishing with worm as bait was the most common method (39% of anglers interviewed) and also resulted in the greatest number of salmon being caught (61% of all salmon). The 1994 census data were collected from all areas of the Ribble system during the months of June to October. The data presented here are for anglers fishing for salmon only or for those fishing for salmon and sea trout at the same time. All of the fish caught were salmon.

    Description: As part of the River Lune juvenile salmonid investigation, a number of sites on the River Wenning catchment were electrofished annually from 1981 - 1985. Particularly low Salmon parr populations were evident for much of the Wenning catchment which has caused some concern. All the Wenning catchment electrofishing results are reported in this paper and comparisons are made with designated groups of sites on the remainder of the Lune catchment. These groups of sites are: River Lune and tributaries, upstream Tebay, Upper Middle Lune, Lower Middle Lune, Lower Lune, Birk & Borrow Becks, Chapel & Crosdale Becks, Rawthey system, Barbon & Leek Becks and the Greta system. The general scarcity of Salmonids in large sections of the main river Wenning probably reflects the apparent limited natural spawning areas on the catchment. Details of Salmon fry and ova planting on the Wenning catchment since 1981 have been collated and whilst survival through the 0+ stage appears to be quite good, recruitment to the 1++ stage appears to be poor. Water quality does not appear to be responsible for the very low salmonid densities at some main river sites but is possibly a factor in apparently preventing any Salmon run in Keasden Beck. Recommendations for future Fisheries and Biological work are given.

    Description: This report presents data from the juvenile salmonid fish stock assessment which is part of the routine Environment Agency riverine monitoring programme. A total of 110 sites was electrofished throughout the Lune catchment between 15th July 1997 and 14th October 1997. These sites included 84 that had been previously sampled in the last comprehensive survey of the catchment, in 1991. The aim of this survey was to assess the distribution and abundance of juvenile salmon and trout in the River Lune catchment and to compare results with those of previous surveys.

    Description: Stocks Reservoir is situated amidst the Forest of Bowland in the upper reaches of the old river valley of the Hodder.The reservoir was built in 1927 for the Fylde Water Board who primarily supplied water to Blackpool. The objective of this study is to assess the degree and likelihood of fish ingress onto the fish plates at the present and proposed stocking densities. An additional aim is to evaluate the operational implications, and if necessary suggest methods of alleviating the problem. Three spheres of study have been undertaken to achieve these objectives, these being: 1. To selectively stock the reservoir and monitor the angling club catches in order to assess the total population, relating it to fish plate losses and proposed stocking densities. 2. To monitor the fish taken from the fish plates and assess the reasons for their ingress. 3. To study the draw off tower and fish plates, and suggest ways of ameliorating or halting the loss of fish and consequent operational problems.

    Description: This report details the results from water quality surveys, carried out in August 1986, which were designed to examine the condition of the Crossens Estuary when receiving primary treated effluent from Southport STW. The results are compared with previous surveys in 198 2 and 1984 when various degrees of secondary treatment were provided. The findings demonstrate that the reduction in the level of treatment has resulted in longer periods of deoxygenation throughout the estuary, but that this has not resulted in any major change in the use or characteristics of the estuary. The estuary remains in Class C.

    Description: The Ribble catchment is the largest and most diverse river system within National Rivers Authority (NRA), North West's Central Area. The river is approximately 100km in length and rises in a limestone area west of the Pennines. This report examines changes in the size and composition of the salmon and sea trout catches from the Ribble migratory salmonid fisheries during the years 1937 to 1991. Comparisons are made between the rod and net fisheries for both salmon and sea trout of the Ribble and Hodder. Patterns of catches shown by the Ribble fisheries are compared with those of other individual rivers and with patterns for the North West Region as a whole. An attempt is made to identify if any relationship exists between catch and stock abundance. Catch patterns shown by the Ribble and Hodder salmon fisheries are compared with electronic resistivity counter data from the two rivers. Annual salmon catch patterns and redd count data are compared both locally and regionally. Recommendations for future studies are made in the light of the report's findings.

    Description: Fisheries technical staff from the North West Central Area of the National Rivers Authority (NRA) currently provide a service for the ageing of salmon scales from fish caught by anglers on the Rivers Ribble and Hodder in order to gather information on the biological characteristics of the salmon population on the River Ribble system in terms of weight, freshwater age and sea age.At the beginning of each fishing season, scale envelopes are distributed by the NRA to angling clubs and some individual anglers. Scales taken from salmon caught on the rivers are returned to the NRA Central Area Office by the anglers, or more often, by NRA bailiffs. The age of each fish caught is then determined by the identification and counting of annuli for both the river and sea zones on the scale. Information is provided by the angler on the scale packet concerning the length and weight of the fish caught, and the date, location and method of capture. Both this information and the age of the fish is recorded on a database. These data can be used to investigate the distribution, and exploitation patterns of the different age classes of the salmon stock within the river system. This report is principally concerned with the scale samples received in 1994, although comparison is also made with samples from 1993 and 1992. References to data will all relate to that received in 1994 unless an alternate year is stated.

    Description: Blackpool, Lytham St. Anne's and Southport are household names as popular leisure and holiday resorts the length and breadth of the land. Their location at the mouth of the estuary of the River Ribble is much less well known, yet this same estuary is of paramount importance to both the economy and the environment of North West England. Indeed, the Ribble Estuary is of international importance for interests as diverse as wintering and migrating wild birds on one hand to the modern aerospace industry on the other. This brochure provides a brief introduction to the estuary of the River Ribble including a historic overview of the people living near the estuary, agriculture and wildlife.

    Description: The River Lune rises in the hills around Tebay in thje North of England and runs through rural farming country to Morecambe bay. It is generally considered as a river of high purity and unspoiled nature. The salmon fishery was at one time considered amongst the best in England and Wales, with very high catches to both rod and net fishermen. During the late 1960's the disease UDN decimated the stock. Since then there has been a recovery of the stock, but this is considered by most anglers and netsmen to be a partial recovery of some of the previous stock components. In recent years anglers and netsmen have voiced their concerns over the Lune stock and have lobbied for action to improve the Lune fishery. This net limitation order (NLO) and the separate byelaw in conjunction with habitat improvement are proposed as part of the strategy for future conservation and management of this salmon fishery. The fishery is currently exploited by 37 licensed netsmen, the highest number of any single estuary in England and Wales. There are 26 haaf, 10 drift and 1 seine nets available. Current estimates of the rod fishery are that 1100 to 1400 anglers fish 14 000 days per year. The River Luhe is one of the few rivers within England and Wales that has the benefit of an accurate fish counter. The counter is at Forge Weir approximately 4 km upstream of the tidal limit. The counts, together with records of the catches from the rod and net fishery, enable a reasonably accurate assessment of both rod and net exploitation. Extensive surveys of the juvenile population, carried out in 1991 and 1997, provide additional information. The purpose of this document is to describe and explain the current state of the salmon population in the River Lune and in doing so, demonstrate the current need for stock conservation. A second purpose is to demonstrate that the proposed NLO and byelaw package should allow the salmon population to reach its conservation target (spawning escapement target).
