    Description: This is the Salmonid & Freshwater Fisheries Statistics for England & Wales 1992 produced by the National Rivers Authority (NRA) in 1994. This report is focused on the maintenance, improvement and development of fisheries of England and Wales. This report is the fourth compilation of salmon and migratory trout catch statistics for England and Wales published by the National Rivers Authority. For the years 1983-88, these statistics were published by the Ministry of Agriculture, Fisheries and Food (MAFF), Directorate of Fisheries Research in their Data Report Series. Other than for rod catches, the 1992 data have been presented in a broadly similar format to those of 1991, Presentation of the rod data however has changed considerably due to the introduction in January 1992 of the first National Rod Fishing Licence. This report makes a general review of different catches: Northumbria, Yorkshire, Anglian, Thames, Southern, Wessex, South West, Severn-Trent, Welsh and North West.

    Description: This is the Acid waters in North West England: The effect of liming agricultural land on the chemistry and biology of the River Esk, North West England report produced by National Rivers Authority in 1992. This report focuses on the study of Acid Waters in the North West Region of England, UK, which began in 1982 and sampling was completed in October 1990. This work was initiated because of the observation of the simultaneous mortality of adult and juvenile salmon and sea-trout in both the River Esk and adjacent River Duddon in June 1980. Investigations at that time indicated that an "acid episode" was the most likely cause of this mortality. A land use study indicated that a reduction in agricultural liming may have been a major factor in the development of acid episodes and consequent fish kills in the River Esk and River Duddon. However there was no evidence that the mortalities of salmonids in the early 1980's were due to a reduction in agricultural liming. They were due to some other phenomenon such as a period of intense acid deposition.

    Description: This is the Wetland resource evaluation and the NRA's role in its conservation: Resource assessment report produced by the National Rivers Authority in 1995. This R&D document provides a strategy for the assessment of the wetland resource of England and Wales. As a first step the report defines wetlands in their UK context. The following working definition is suggested: Wetland is land that has (or had until modified) a water level predominantly at, near, or up to 1.5 m above the ground surface for sufficient time during the year to allow hydrological processes to be a major influence on the soils and biota. These processes may be expressed in certain features, such as characteristic soils and vegetation. The report also summarises a hydrotopographical classification of wetlands. The report then develops a strategy for the establishment of a wetland resource Inventory based on a geographical information system (GIS) as a means of storing and manipulating site data from across England and Wales.

    Description: This is the Wetland resource evaluation and the NRA's role in its conservation: Classification of British wetlands report produced by the National Rivers Authority in 1995. This R&D document provides a clear classification for wetlands in England and Wales. The classification incorporates many of the existing ideas on the subject but avoids some of the problems associated with other classifications. A two-layered 'hydrotopographical' classification is proposed. The first layer identifies situation-types, i.e. the position the wetland occupies in the landscape, with special emphasis upon the principal sources of water. The second layer identifies hydrotopographical elements, i.e. units with distinctive water supply and, sometimes, distinctive topography in response to this. This system is seen as an independent, basic, classification upon which it is possible to superimpose additional, independent classifications based on other features (e.g. base-status, fertility, vegetation, management etc.). Some proposals for such additional classifications are provided.

    Description: This is the report on Lakes – Classification and Monitoring, a strategy for the classification of lakes by the National Rivers Authority.This report describes a scheme for the assessment and monitoring of water and ecological quality in standing waters, greater than about 1ha in area, in England and Wales although it is generally relevant to Northwest Europe. Thirteen hydrological, chemical and biological variables are used to characterize the standing water body in any current sampling. Statistical testing on the chemical variables showed that at least six samples during a year would be needed to produce a representative sampling mean; but in this scheme the choice of variables minimizes logistic cost by not using boat sampling and time costs by not demanding extensive taxonomic work. Standing waters are classified in a state-changed system in which the contemporary values of the variables are compared with a reference baseline state and then placed in categories of percentage change from this baseline. The scheme is presently designed for use at about five year intervals on all lakes greater than 2ha area plus additional lakes of significant amenity or conservation interest.

    Description: This is the Cheshire stillwaters. Summary results of 1997 data Oak Mere, Betley Mere and Marbury Big from the National Rivers Authority, June 1998. In May 1997, a Stillwaters meeting was held to discuss the way forward in stillwaters monitoring. It decided upon the establishment of a three year rolling programme, in which three stillwaters would be monitored three times a year, every third year. The stillwaters where chosen due to water quality (i.e potential polluted / sensitive waters), fisheries and ecological interests. The Still waters chosen for the first year (1997) were Oak Mere, Betley Mere and Marbury Big Mere. The surveys were aimed to produce a comprehensive study of the still water through monitoring a variety of parameters. Algal, zooplankton and water chemical samples were taken three times a year, (April, July and September). In addition, fisheries surveys were taken in July and marginal invertebrate surveys taken in September.

    Description: This is the River Gowy rapid corridor survey July 1995: Ecology South Mersey report produced by the National Rivers Authority North West Region in 1995. This report looks at the survey carried out by the South Mersey Ecology Team prior to routine deweeding operations on the main River Gowy at the end of July, 1995. The survey covered Flood Defence Stretch References RGOW03 to RGOW16. These stretches were further divided into a series of 43 stretches, each one being approximately 500m in length for ease o f mapping by Ecology. Recommendations for each length have been cross-referenced with the Bill of Quantities where possible, e.g. retention o f margins. In Flood Defence stretch RGOW03, the South West Winter Wetland forms an important habitat for birds. In stretches RGOW04 to RGOW05, the Gowy Meadows and Ditches have been designated a Grade A, Site of Biological Importance, by Cheshire County Council due to the nature of the acidic grassland and diverse ditches. In stretches RGOWIO to RGOW11 the left bank forms Hockenhull Platts, Grade A Site of Biological Importance and County Trust Reserve. In stretches RGOW15 to RGOW16, the area from Mill Farm to the Shropshire Union Canal is a Grade A Site of Biological Importance. These sites are very sensitive and detailed recommendations for working practices can be found in the relevant sections o f the survey.

    Description: This is the NRA's role in wetland conservation report produced by the National Rivers Authority in 1995. This document is the third of a series of three R&D Notes produced as part of an integrated research programme addressing aspects of the NRA's role in wetland management and conservation. Chapter 1 considers the nature of the wetland resource and its definition. Chapter 2 presents the NRA's current legislative and policy framework relating to its role in wetland conservation. National and international legislation and agreements are considered, and particular attention is afforded to the potential implications of the 'Habitats Directive'. Chapter 4 presents key examples of operational casework involving wetlands. Differences in approach and external perceptions of the NRA's current and likely future role in wetland conservation are discussed within Chapter 5. Other issues highlighted in this report are: policy guidance required on NRA’s role in land drainage; standard of flood defence service for wetlands; cost-benefit analysis; strategies for halting and reversing the decline and degradation of wetland resource; and Catchment Management Planning.

    Description: This is the Cheshire Meres 1994 November surveys report produced by the National Rivers Authority in 1995. The report focuses on some of Cheshire meres, which were showing evidence of increasing eutrophication, commonly due to anthropogenic inputs. Concern for the deterioration of the water quality of still waters has been translated by incorporating these priorities into the NRA North West Regional Environmental Strategy for Stillwaters. The meres were also being investigated as possible polluted waters under the EC Nitrate Directive.The ultimate aim is to formulate lakes management options in order to help preserve North West still waters and minimise future restoration programmes. For such pro-active work to be carried out, sufficient background data must be available. It should then be possible to fully assess the current status of these lakes, identify seasonal trends and detect significant point/diffuse pollution inputs. These surveys were the first of a series, and it was intended to repeat similar surveys in Summer and Autumn 1995, and include a further 20 meres.

This report identified key rare and nuisance species of interest to the NRA and prioritised research needs to develop conservation strategies for these species. The NRA has in the past adopted a habitat maintenance and protection approach to conservation paying less attention at individual species. There is a risk that conservation based on a habitat management policy will no further the conservation of certain species. In addition, certain ‘nuisance’ species cause problems for conservation by having a negative impact on more valued species or ecosystems. Through the combination of the review of current legislation and literature and consultation with NRA staff, this project identified key rare and nuisance species of interest to the NRA and prioritised research needs to develop conservation strategies for these species.

    Description: This is the Species management in aquatic Habitats WRc Dec 1993 produced by the National Rivers Authority in 1993. This report is focused on the Phase 1 of the Species Management in Aquatic Habitats, based on the Development of priority lists of rare and nuisance species for the National Rivers Authority (NRA). Certain ‘nuisance’ species cause problems for conservation by having a negative impact on more valued species or ecosystems. This project was initiated as part of a programme of research to develop strategies for the management of both rare and nuisance species. This project identified key rare and nuisance species of interest to the NRA and prioritised research needs to develop conservation strategies for these species. A combined provisional list of almost a thousand rare species, a priority list of 58 species of potential interest and a priority list of nine nuisance species was developed by a process of literature review and from suggestions by NRA conservation staff.

    Description: This is the Salmonid & Freshwater Fisheries Statistics for England & Wales 1990 produced by the National Rivers Authority (NRA) in 1992. This report is focused on the maintenance, improvement and development of fisheries of England and Wales. This report is the second compilation of salmon and migratory trout catch statistics for England and Wales published by the National Rivers Authority (NRA). Before 1989, these statistics were published by the Ministry of Agriculture Fisheries and Food (MAFF) Directorate of Fisheries Research in their Data Report Series. The 1990 data have been presented in a broadly similar format to those of 1989. However, two further NRA regions, four in all, provided effort data for rod fisheries in 1990. This report makes a general review of different catches: Northumbria, Yorkshire, Anglian, Thames, Southern, Wessex, South West, Severn-Trent, Welsh and North West.

    Description: A number of wells penetrating the Floridan aquifer in easternClay County were found to be losing water to permeable zones abovethis aquifer. A differential in artesian pressure was observed in closelyspaced wells of similar depth. Further investigation. revealed thatthe pressure differential in the wells was due to the design of thewells, of which there were four principal types.A comparison of the four types of wells in relation to the subsurfacegeology showed that three types of wells were open to the permeablezones above the Floridan aquifer. In such wells water of relativelyhigh head from the Floridan aquifer moves up through the well boreand out into zones of relatively low head.The estimated water loss from poorly designed wells rangedfrom 32 to 180 gpm (gallons per minute). The artesian head loss inleaky wells ranged from 3 to 15 feet. A total loss of water of 39 mgd(million gallons per day) was estimated from all the leaky wells inthe area. A significant decline of the piezometric surface of the Floridanaquifer was observed in eastern Clay County. Some of this decline canbe attributed to the loss of water from the Floridan aquifer throughthese poorly designed wells. (Document has 16 pages.)

    Description: The water problems confronting Hallandale are similar to those of othercoastal cities of southeastern Florida which are undergoing rapid growthwith tremendous increase in water demand. The highly permeable Biscayneaquifer underlying the Hallandale area is an excellent source ofwater; however, the permeable nature of the Biscayne aquifer would permitthe intrusion of sea water, if fresh water levels were lowered excessively,as well as the infiltration of urban or industrial contaminants, fromland surfaces and surface water bodies.This study is to provide the hydrologic data necessary for proper waterresource development and planning in the Hallandale area.(40 page document)

    Description: Salt-water encroachment is undoubtedly the problem of most concern tousers of ground water in Florida. This is a problem in many coastal areaswhere water levels are lowered excessively by heavy pumping. It is aproblem also in some inland areas where the water-bearing formations containsalty water at relatively shallow depths. Among the coastal areas where wellshave become contaminated with salt water are Pinellas County and the Miamiarea of Dade County. Inland areas where wells are likely to become contaminatedwith salt water include Seminole County and the southwestern partof Volusia County.The purpose of the investigation is to make a detailed study of thegeology and ground-water resources of the county with special emphasis onthe problems associated with declining water levels and salt-watercontamination. This report reviews briefly the progress of the investigationthrough February 1954. (PDF contains 43 pages.)

    Description: Recently there has been much activity in reclaiming thelow-lying coastal areas of Dade County for residential use,by the addition of fill. The fill is obtained by digging canalsboth normal to and parallel to Biscayne Bay. The canalsserve the additional purpose of providing an access to theBay for boats. A problem needing to be considered is theeffect that these canals will have on the ground-water resources.It is expected that the canals will have little effecton ground water in parts of the county distant from the coast,but their effect in coastal areas is a matter of concern. Inorder to predict what, may happen in the vicinity of thesenew canals if they are not equipped with adequate controlstructures, it is instructive to review what has happened inthe vicinity of similar canals in the past.The U. S. Geological Survey, in cooperation with DadeCounty, the cities of Miami and Miami Beach, the Centraland Southern Florida Flood Control District, and the FloridaGeological Survey has collected water-level and salinitydata on wells and canals in Dade County since 1939. Someof the agencies named, and others, collected similar databefore 1939. Analysis of all the data shows that sea waterin the Atlantic Ocean and Biscayne Bayis the sole source ofsalt-water contamination in the Biscayne aquifer of the DadeCounty area. (PDF has 19 pages.)

    Description: The rapidly expanding population and economic growth in the sevencounties of the East Central Florida Regional Planning Council as shown inFigure 1, herein called the East Central Florida Region or the Region, hasresulted in increasing demands on its water resources. Although there isabundant water in the Region as a whole, the water in some areas of the Regionis of unacceptable quality for most uses. As the population increases the demandfor water will become much greater and the available supply may be reduced bypollution and increased drainage necessitated by urbanization and other landdevelopment- Ground-water supplies can be increased by capturing and storingwater underground that now drains to the sea or evaporates from swamp areas.Research is needed, however, to develop artificial-recharge methods that arefeasible and which will preserve or improve the quality of water in the aquifer.(PDF contains 57 pages)

    Description: In recent years, difficulties encountered in obtaining ground-water supplieswith acceptable chemical characteristics in the Myakka River basin area led tothe implementation of a test drilling program. Under this program, well drillingand data collection were executed in such a manner that all water-producingzones of the local aquifers, together with the quality and quantity of the wateravailable, were effectively identified.A step-drilling method was utilized which allowed the collection offormation cuttings, water samples, and water-level data, from isolated zones inthe well as drilling proceeded. The step drilling procedure is described. Thedriller's logs, geophysical logs, and chemical quality of water tables arepresented.(Document has 66 pages.)

    Description: Charlotte, De Soto, and Hardee counties are east-southeast ofTampa in west-central peninsular Florida, figure 1. In order toplan the future water-resource development of the area, informationabout the water resources is needed. To meet this need, the WaterResources Division of the U.S. Geological Survey, in cooperationwith the Peace River Basin Board of the Southwest Florida WaterManagement District as part of the statewide cooperative programwith the Division of Geology, Florida Board of Conservation, begana continuing hydrologic data collection program in July, 1963, asan initial step in the investigation and evaluation of the groundwaterresources of Hardee and De Soto counties. A similar hydrologicdata program commenced in Charlotte County in July, 1964.Previous work in Hardee and De Soto counties included aone year reconnaissance by the Division of Water Resources andConservation, Florida Board of Conservation, which concluded inJune, 1963, and resulted in a hydrologic report (Woodard, 1964).As an outgrowth of the hydrologic data program, a Map Seriesreport portraying the chemical character of water in the Floridanaquifer in the southern Peace River basin was prepared in 1967(Kaufman and Dion).The data contained herein constitute the basis for the MapSeries report. Additional selected data, including records of wellsand chemical analyses,, on the ground-water resources of the threecounty area are also included and are published to make the dataavailable.(Document has 28 pages.)

    Description: A large part of western Manatee County is devoted to the growing ofwinter vegetables and citrus fruits. As in most of peninsular Florida,rainfall in the county during the growing season is not sufficient for cropproduction and large quantites of artesian water are used for irrigation.The large withdrawals of artesian water for irrigation result in a considerabledecline of the artesian head in the western part of the county. This seasonaldecline of the artesian head has become larger as the withdrawal of artesianwater has increased. The lowering of the fresh-water head in some coastal areas in the Statehas resulted in an infiltration of sea water into the water-bearing formations.The presence of salty water in the artesian aquifer in parts of the coastal areaof Manatee County indicates that sea water may also have entered the waterbearingformations in this area as a result of the decline of artesian pressureduring the growing season. The purpose of the investigation is to make a detailed study of the geologyand ground-water resources of the county, primarily to determine whethersalt-water encroachment has occurred or is likely to occur in the coastal area.

    Description: Five short bottom sediment cores taken in Wakulla Spring Wakulla County, Florida, were described lithologicallyand sampled for palynological study. Four of the cores were recoveredfrom sediments at the spring cave entrance(130 feet water depth). One core was taken in a fossil vertebrate bone bed, 280 feet distance into the main springcave at a water depth of 240 feet. Sediments in the cores are composed of alternating intervals of quartz sand andcalcilitite, containing freshwater diatoms, freshwater mollusk shells and plant remains. The predominant pollenpresent in all cores consists of a periporate variety typical of the herb families Chenopodiaceae and Amaranthaceae.Arboreal flora, typical of the area surrounding the spring today, represent a very low percentage of thle pollenassemblage in the cores. Clustered Chenopod-Amaranth type pollen observed in one core suggest minimal transportprior to deposition, and indicate that the bottom sediments in the cave may be essentially In situ. An absence ofexotic flora suggests a Quaternary age for the sediments. (PDF contains 11 pages.)

First sampled in 1947, resampling and reanalyzing the waterfrom these wells was used to determine the change in the chloridecontent of the ground water from 1947 to 1956. The chloridecontent of ground water is generally a reliable indication ofthe contamination of ground water by sea water, as 90 percent of the dissolved solids of sea water are chloride salts.

    Description: The principal sources of surface-water supplies inBakerCounty are the St. Marys River and its tributaries. However,the flow of many of the small tributaries is intermittent, andwithout storage they are not dependable sources of supplyduring sustained periods of deficient rainfall.Of the six stream-gaging stations in Baker County forwhich complete records are available, one has been in operationfor 31 years and provides a long-term record upon whichto base correlative estimates for extending the short-term records at the other stations. All available streamflow datato 1957 have been summarized in graphic or tabular form.The hydrologic balance between minimum streamflowsand increased evaporation losses afforded by potential shallowreservoirs provides design criteria for determining the maximumsurface area of effective reservoir that can be createdat a selected site within Baker County. This information hasbeen presented in graphic and tabular form in the report.(PDF has 37 pages.)

    Description: Practically all water for municipal and industrial usein the Fernandina area is supplied by artesian wells. Inrecent years, the use of artesian water in the area has increasedto meet the needs of expanding industry and increasingpopulation. The total industrial and municipal pumpagehas increased from approximately 35 million gallons per dayin 1941 to approximately 50 million gallons per day in 1959.Correlated with the increase in water use is the constantdecline in the artesian pressure in the area. In many otherareas in Florida, such a decline in artesian pressure hasresulted in salt-water intrusion into the fresh-water supply.An intrusion of salt water in the Fernandina area would contaminatethe existing fresh-water supply and would resultin a hardship for the population and seriously injure theeconomy.Recognizing the threat to the fresh-water supplies ofthis area, the U. S. Geological Survey in cooperation withthe Florida Geological Surveymade a reconnaissance to determineifthere has been any intrusion of salt water into thefresh-water supply or if there is any danger of future intrusion.

    Description: The Green Swamp area in central Florida is anotherarea where man is developing agricultural land from marginalland. Though the area is by no means as extensive asthat of the Everglades, the present efforts for its developmentare similar to the early efforts for developing the Evergladesin that many miles of canals and ditches have beenconstructed to improve the drainage.Lest the early mistakes of the Everglades be repeated,the Florida Department of Water Resources considered thatan appraisal of the physical and hydrologic features of thearea was needed to determine the broad effects of drainingand developing the swamp. This reconnaissance provides information requiredby the State of Florida for determining its responsibilityand policy in regard to the Green Swamp area andfor formulating future plans for water management of thearea.Some of the features that have been determined are:the amount of rainfall on the area; the pattern of surfacewaterdrainage; the amount and direction of surface-waterrunoff; the direction of ground-water movement; the interrelationshipof rainfall, surface water, and ground water;the effects of improved drainage facilities'; and the effectsof the hydrologic environment on the chemical quality ofwater of the area.(PDF contains 106 pages.)

    Description: The Oakland Park area obtains its water from the Biscayne aquifer,S composed of very permeable and porous, sandy limestones. The per-3 meability of the aquifer increases with depth, and wells in the area〈\ generally obtain water at depths ranging from 60 to 80 feet, or betweenS 100 and 200 feet, depending on the quantity of water desired. Thedata presented in this paper can be used for further development ofwater and wise management of resources in the area. Large quantitiesS of ground water are still available at Oakland Park, if salt-water encroachmentcan be controlled. The data in this study provide the necessaryinformation to begin an effective water management program.(PDF has 49 pages)

    Description: Future water needs in southern Florida call for an increase in the storagecapacity of Lake Okeechobee. Seepage from the lake is expected to increase as aresult of raising the lake level. Data concerning the occurrence and amounts ofseepage are needed for the design and operation of flood-control works whichwill remove excess water from the rich agricultural lands along the southernshore. Intensive studies at five sites along the southern shore of LakeOkeechobee between the Caloosahatchee Canal and the St. Lucie Canal indicatethat seepage occurs chiefly through beds of shell and limestone which underliethe Hoover Dike at shallow depth. Seepage rates at the five sites range fromabout 0.1 to 0.9 cfs per mile per foot of head across the dike. Seepage beneaththe 50-mile length of dike should increase from about 22 to 50 cfs if the averagestage of the lake is raised from 14 to 16.5 feet. Seepage is greatest betweenMoore Haven and Clewiston, where deep borrows have been excavated on thelandward and lakeward sides of the dike. Most of the seepage from the lake canbe controlled by properly spaced toe ditches which would intercept the seepageand return it to the lake. (PDF contains 108 pages.)

    Description: Upper Old Tampa Bay, a 17-square mile area of Old Tampa Bay, Florida,has been proposed for conversion to a fresh-water lake. The amount of runoff tothe proposed lake and its chemical quality are both adequate to freshen andsustain a fresh-water lake in this part of the bay. During 1950-66 runoff to theproposed lake, including discharge from Lake Tarpon, would have averaged 134mgd (million gallons per day) and would have displaced the volume of theproposed lake at normal pool stage (2.5 feet above mean sea level) about 1.7times per year. Without discharge from Lake Tarpon, the volume of theproposed lake would have been displaced 1.2 times. If the lake level was initiallyat a normal pool stage during a critically dry year, such as 1956, the proposedlake would have declined 0.25 to 0.5 foot below the minimum design level, (1.5feet above mean sea level).(44 page document)

    Description: Upward leakage of saline water from an artesian aquifer below 1,500 feethas caused an increase in chloride concentration in the lower Hawthorn aquiferfrom less than 1,000 mg/1 (milligrams per liter) to values ranging from about1,300 to 15,000 mg/1. Similarly the higher temperatures of the intruding waterhas caused an increase in water temperatures in the aquifer from 82"F to valuesranging from 83 to 93"F. The intruding water moves upward either through theopen bore hole of deep wells or test holes, or along a fault or fracture system,which has been identified in the area. From these points of entry into the lowerHawthorn aquifer, the saline water spreads laterally toward the south andsoutheast, but is generally confined to components of the fault system.The saline water moves upward from the lower Hawthorn aquifer into theupper Hawthorn aquifer through the open bore hole of wells, which connect theaquifers. This movement has resulted in an increase in chloride from less than200 mg/1 in the unaffected parts of the upper Hawthorn aquifer to valuescommonly ranging from about 300 to more than 3,000 mg/1 in parts of theaquifer affected by upward leakage. The upper Hawthorn aquifer is the principalsource of ground-water supply for public water-supply systems in western LeeCounty.Similar effects have been noted in the water-table aquifer, where chlorideincreased from less than 100 to concentrations ranging from about 500 to morethan 5,000 mg/1. This was caused by the downward infiltration of waterdischarged at land surface from wells tapping the lower Hawthorn aquifer.The spread of saline water throughout most of the McGregor Isles area iscontinuing as of 1971.(40 page document)

It was foundthat many of the streams of the water shed were virtually dryduring part of every year. However, the basins of the Myakkalakes, through which the river flows offer some storage potential,that if properly developed would provide a continuance drift ofabout seven million gallons of water per day of good quality waterthat would be high in color and temperature upon occasion. Withreasonable treatment some of this water could be used to meetthe present needs of the rapidly expanding coastal areas. (PDF contains 40 pages.)

    Description: Floods occurred on streams in the vicinity of Perry,Taylor County, Florida, on June 9, 1957, as a result of heavyrains from atropical disturbance. Serious flooding occurredin Perry along Spring and Pimple creeks as outlined by theshaded area in figure 1, requiring the evacuation of aboutZOO families from the lowland area. No loss of life wasreported. The damages to residential and commercial propertieswere estimated at several million dollars. Most ofthe damage was confined to residential areas (fig. 2); however,several stores in the area were damaged by floodwaters (fig. 3).This report presents data pertaining to the rainfallaccompanying this storm and peak flows of Spring and Pimplecreeks in Perry. It contains flood elevations at severalpoints, and peak discharges of the two creeks flowing throughPerry. The report also contains a discussion of the rainfallassociated with the flood and a description of the generalfeatures of the flood. (PDF contains 16 pages.)

The purposes of this investigation were:(1) to determine the occurrence and chemical quality ofwater in the streams and lakes, (2) to determine the locationand the thickness of aquifers, and (3) to determine theoccurrence and chemical quality of the ground water. Duringthe period from 1933 to 1954, water records were collectedfrom a few stream-gaging stations and a few observationwells. The purpose of this report is to present basic datacollected during these investigations. (Document has 188 pages.)

    Description: Florida's lakes have played an important roll in thedevelopment of the state and day by day they are becomingmore important. The future well-being of the state dependsto a large extent on the wise management of this valuablenatural resource. Wise management needs large amountsof information and, yet, published information about Florida'slakes has consistently fallen behind the need.Recognizing this fact, the Trustees of the InternalImprovement Fund entered into cooperative agreements withthe U. S. Geological Survey to provide for the collection anddissemination of lake information.This report, prepared at Ocala, Florida, under thesupervision of A. O. Patterson, district engineer, U. S.Geological Survey, is part of the work. It has been writtenwith the sincere hope that the knowledge it imparts will leadto the solution of some of the lake problems that Floridafaces today.

    Description: bulletinwhich documented the major and important springs in the state (Ferguson et al., 1947).This publication was revised in 1977, with many previously undocumented springs andmany new water-quality analyses being added (Rosenau et al., 1977). The FloridaGeological Survey's report on first magnitude springs (Scott et al., 2002) was the initial stepin once again updating and revising the Springs of Florida bulletin. The new bulletinincludes the spring descriptions and water-quality analyses from Scott et al. (2002). Nearly300 springs were described in 1977. As of 2004, more than 700 springs have been recognizedin the state and more are reported each year. To date, 33 first magnitude springs (with aflow greater than 100 cubic feet per second or approximately 64.6 million gallons of waterper day) have been recognized in Florida, more than any other state or country (Rosenau etal., 1977). Our springs are a unique and invaluable natural resource. A comprehensiveunderstanding of the spring systems will provide the basis for their protection and wise use.(Document pdf contains 677 pages)

Duringthe last half century large developments of ground water have beenmade, and new developments are currently being addedi However, althoughproblems of supply, some of them critical, have arisen in certain areas,vast quantities of ground water are:yet available for development over amajor part of the State. It is quite conceivable that the availabilityof large developed water resources in Florida, in contrast with theshortages of supply in many other parts of the country, may play a dominantrole in the agricultural and industrial growth of the State.

    Description: One of the causes of lower artesian pressure, waterwaste and aquifer contamination is the misuse and insufficientcare of artesian wells. In 1953, Senate Bill No. 57, entitled"An Act to Protect and Control the Artesian Waters of theState" (see Appendix) became a law. This law was passedthrough the efforts exerted by leading members of the Senateand the House of Representatives, who understood the needfor a wise and controlled expenditure of our most valuablenatural resource.The State Geologist and his authorized representativeswere designated by this law to enforce this conservationmeasure; however, no financial provision was included forthe 1953-55 biennium. The proposed program of the FloridaGeological Survey for this biennium did not include the fundsnor provide any full-time personnel for the enforcement ofthis statute. As a result, little actual work was accomplished during these two years, although much time was given toplanning and discussion of the problem.Realizing that this program could provide additional basicdata needed in the analysis of the water-supply problem, theState Geologist sought and was granted by the 1955 Legislatureadequate funds with which to activate the first phase of theenforcement of Florida Statute No. 370.051-054.Enumerated below is a summary of the progress madeon this investigation as outlined previously:1. Data have been collected on 967 wildly flowing wellsin 22 counties.2. Chloride determinations have been run on 850 of the967 wells.3. Of the 967 wells, 554 have chlorides in excess of the250 ppm, the upper limit assigned by the State Boardof Health for public consumption.4. Water escapes at the rate of 37, 762 gallons per minutefrom these 967 wells. This amounts to 54, 377, 280gallons per day.The investigation is incomplete at this time; therefore,no final conclusions can be reached. However, from dataalready collected, the following recommendations are proposed:1. That the present inventory of wildly flowing wells becompleted for the entire State.2. That the current inventory of wildly flowing wells beexpanded at the conclusion of the present inventoryto include all flowing wells.3. That a complete statewide inventory program beestablished and conducted in cooperation with theGround Water Branchof the U.S. Geological Survey.4. That the enforcement functions as set down in Sections370.051/.054, Florida Statutes, be separated fromthe program to collect water-resource data and thatthese functions be given to the Water ResourcesDepartment, if such is created (to be recommendedby the Water Resources Study Commission in a waterpolicy law presented to the 1957 Legislature).5. That the research phase (well inventory) of the programremain under the direction of the Florida GeologicalSurvey. (PDF contains 204 pages.)

    Description: There is a need to determine quantitative relationships between fishery status and water quality in order to make informed judgements concerning fishery health and the setting of environmental quality standards for fishery protection. Such relationships would also assist in the formulation of a system for classifying fisheries. A national database of fisheries and water quality has been collated from the archives of pollution control authorities throughout the UK. A number of probable and potential water quality effects on fish populations have been identified from a thorough analysis of the database, notwithstanding large confounding effects such as habitat variation and fish mobility, and the generally sparse nature of water quality information. A number of different approaches to data analysis was utilised, and the value of each has been appraised. Recommendations concerning the integration of water quality assessment approaches have been made and further research on fishery status, and its measurement, in relation to water quality has been suggested.

    Description: This report considers the development of environmental quality standards (EQSs) for the salmonid fishery, cyprinid fishery, migratory fishery, commercial harvesting of marine fish for public consumption and commercial harvesting of shellfish for public consumption uses of controlled surface waters. Previous reports have been used to identify those parameters necessary for the maintenance of these five uses. Each water use is considered in a separate section within which identified parameters are discussed and standards proposed, a summary of the proposed standards is presented at the beginning of the relevant section. For salmonid, cyprinid and migratory fisheries, EQSs for substances in water have been proposed for the protection of these fisheries. For the commercial harvesting of marine fish and shellfish for public consumption uses 'Warning Levels' of substances in waters have been proposed. These 'Warning Levels' have been proposed by considering data on bioaccumulation and food standards and aim to prevent acceptable intake values and concentrations in fish/shellfish flesh exceeding statutory or recommended levels. For the commercial harvesting of marine fish for public consumption it has been concluded that the current EQSs for most List II substances for the protection of salt water life should be adequately stringent to protect this use, however for the commercial harvesting of shellfish for public consumption, these List II EQSs do not appear adequate to protect this use and more stringent 'Warning Levels' have been proposed. For all five uses considered in this report there has been found to be limited information on a number of the parameters considered and in general for indigenous species, this has been found to be especially so when considering migratory fisheries and the commercial harvesting of marine fish and shellfish.

    Description: During 1993, a comprehensive data set of scale readings, length and weight measurements was established for migratory salmonids on the River Lune. This information was collected using three methods of fish capture: 1. The Lune estuary commercial nets. 2. River Lune Forge weir fish trap. 3. River Lune rod catch scale returns. Additional information was contributed by the Kent, Leven and Duddon rod and commercial fisheries. The data shows that the salmon stock in 1993 was dominated by two year old smolts. This varies from year to year.The sea trout population displays a normal population curve in terms of numbers of fish in each age and weight class. The growth rate of salmon and sea trout is very similar even though salmon have the benefit of high sea feeding.

    Description: Fish tracking is a valuable technique for the provision of detailed information on thebehaviour patterns of individual fish especially during estuarine and riverine migration.2. Tracking studies help in the provision of a comprehensive description of the variety offishbehaviour patterns in response to factors such as water flow, obstructions and waterquality.3. There are advantages to be gained by complementing fish tracking studies with datacollected from fish counters and vice versa.4. An overall evaluation of NRA fish tracking projects is presented in the wider context ofNRA strategic research objectives.5. The requirement for future development of tracking equipment, improved data analysistechniques, better communication and more immediate report preparation is identified.6. Individual project evaluation is given for NRA (or the appropriate Water Authoritypredecessor) tracking studies conducted on the Ribble estuary, the River Tamar, RiverTorridge, Rivers Test and Itchen, River Lodden, the Welsh River Dee, River Glaslyn,River Taff, River Tawe, River Tywi, River Usk, Rivers Avon and Stour and the RiverFrome.7. An outline for future strategic research is provided which identifies particular areas forstudy:-i) Identification of environmental factors which control the entry of fish into rivers.ii) Improvement of the understanding of the relationship between water flow andupstream movement of salmonids.iii) Examination of the detailed movements and behaviour of fish in relation toobstructions.iv) Closer definition of water quality requirements for salmonid fish.v) Definition of habitat preferences of salmonids in rivers.vi) Subsidiary topics such as the movements of non-salmonid fish and the downstreammigration of kelts and juvenile salmonids.

    Description: The study began on the 7th January 1991 and was completed in June 1991. Two reports have been produced. This report published as R&D Note 33 describes NRA trackingstudies, tracking techniques and fish counter technology. The second report published as R&D Note 34 evaluates NRA tracking studies and recommends future research. The latterwill be used solely for NRA management purposes. This report briefly outlines the programme of the NRA, placing the Fisheries programme in the context of the work of the NRA as a whole, and viewing the tracking work against thebroader requirements of the NRA Fisheries research programme. Two techniques currently exist for studying the detailed timing and extent of movements of adult salmon: tracking of individually identifiable fish, and counting the numbers of fish moving past a fixed point in the river. Further details of these techniques and their development are given in Sections 2 and 3. Section 4 summarises and assesses completed and current NRA tracking Studies. Completeproject descriptions for the studies are contained in Appendix A. Section 5 discusses the scientific content of these studies in relation to similar work carried out elsewhere in the UK. Section 6 details the future development of tracking techniques. Tracking work on migratory salmonids has tended to concentrate largely upon the movements of adult salmon. Much of this report will therefore be concerned with salmon trackingstudies. NRA studies involving sea trout are referred to where appropriate. The methodological problems of sea trout tracking studies are summarised in Section 2.1.3.

    Description: In Britain, many birds eat fish in fresh waters but only three species, cormorant, red-breasted merganser and goosander, are commonly perceived to present serious problems for freshwater fisheries. Complaints are mainly that cormorants eat large fish and that all three bird species eat so many juvenile fish, that there are subsequently fewer fish to be harvested or angled, but alsothat persistent predation by birds changes fish behaviour so that they are less 'catchable'.To this end, this report reviews existing information on the current status, foraging ecology, and population biologyof the three bird species as background to their potential impact on fisheries. Discusses fish population dynamics within the context of predation effects. Reviews existing experimental evidence for impacts on fish populations and fisheries; and describes current legislation, discusses potential criteria for serious damage to a fishery, andsuggests ways forward for NRA policy and research.
