    Beschreibung: This is the Investigation of rising nitrate concentrations in groundwater in the Eden Valley, Cumbria report produced by the Environment Agency in 2003. This report focuses on groundwater nitrate concentrations in the Eden Valley. Most boreholes in the Eden Valley had nitrate concentrations less than 20 mg/l but a significant number had higher concentrations, some exceeding the EC maximum admissible concentration for drinking water of 50 mg/l. The main objectives of this report were to investigate the causes of rising nitrate concentrations in groundwater in the Permo-Triassic sandstone aquifers of the Eden Valley area and provide sufficient understanding of the groundwater and surface water flow system, including the sources of the nitrate contamination and the processes controlling nitrate movement, so that possible management options for reversing this trend can be considered.

    Beschreibung: This is a technical report of a hydrogeological assessment by the Environment Agency, an assessment to inform the Stage 3 review of Consents under the Habitats Directive for Wybunbury Moss, a National Nature Reserve and Special Area of Conservation in Cheshire. In the Stage 2 Review of Consents, one groundwater licence could not be clearly assessed as having no significant impact and so was taken forward to Stage 3. Further work has been carried out to refine the understanding of groundwater flow and the extent of the actual groundwater catchment of Wybunbury Moss, including three drilled boreholes, the monitoring of groundwater levels in the boreholes by data-loggers for more than 18 months and the sampling and analysis of the groundwater from the boreholes. Results of this further work are shown in Appendixes. From this work, a geological cross-section and Conceptual Model has been produced, and a map showing the revised understanding of the groundwater catchment of Wybunbury Moss. It also includes in Appendix I, the Stage 2 Review of Consents previously made.

    Beschreibung: This report is the fourth collation of salmon and migratory trout catch statistics for England and Wales produced by the Environment Agency. For the years 1989-94 these statistics were published by the National Rivers Authority (NRA) and for the years 1983-88 by the Ministry of Agriculture, Fisheries and Food, Directorate of Fisheries Research, in its Data Report series. This report is designed to be a reference document of declared salmonid catches in England and Wales. Salmon stock assessment data including provisional catches, counter run estimates and some juvenile data are now published in an annual assessment for the International Council for the Exploitation of the Seas (ICES). The second report in this series was published jointly by the Environment Agency and the Centre for Environment, Fisheries & Aquatic Science (CEFAS) in April 1998 (Anon 1999).

    Beschreibung: This is the River Eden RHS and geomorphology evaluation: Final report October 2001 produced by the Environment Agency North West in 2001. This report analysed the River Habitat Survey (RHS) and geomorphology data to evaluate the level of habitat quality and the geomorphological characteristics of the River Eden and sub-catchments. RHS data and geomorphological assessment data was collected within the study areas by CEH and Fluvial Environmental Services Ltd. The River Eden and its sub-catchments are being considered as a Special Area for Conservation (SAC) due to the presence of habitat types and species, which are rare or threatened within Europe. The purpose of the project is to provide an overview of the state of the catchment in terms of river habitats and geomorphological processes in order to aid the derivation of sound management for this proposed SAC.The aim of this report was to determine the state of the environment within the Eden and sub-catchments and identify the main pressures on the system in order to derive sound management options.

    Beschreibung: This is the Report of 1996 survey of Trout Beck with particular reference to spawning gravel quality and invertebrates as a food source for salmonids produced by the Environment Agency North West. Whilst the main River Derwent is quite a high profile salmon fishery, Trout Beck is not a significant fishery in its own right, but serves to maintain the genetic integrity of the wild populations of trout and salmon in the catchment by providing a unique habitat. This survey addressed the invertebrate food availability, and additionally looked at the substrate to try to determine whether the bed type might actually be unsuitable for spawning, especially in view of the previously mentioned silt inputs.

    Beschreibung: 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.

It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Tavy 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. This Action Plan aims to promote long term collaboration and co-operation between the Agency and other interested parties to effectively and efficiently manage the stock of salmon on the River Tavy.

    Beschreibung: This is the River Axe Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Axe 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. This document is part of a national initiative to produce action plans for the management of all the main salmon rivers of England and Wales by 2003. The aim of this plan is (i) to assess the status of the salmon stocks and fisheries of the River Axe - including the use of Conservation Limits as part of this process, (ii) to identify factors which may be limiting stock and fishery performance and (iii) to propose remedial measures address these factors. The salmon stock of the River Axe was apparently in a healthy state in the 1950s, supporting net and rod fisheries with average annual catches of around 100 and 50 fish respectively. Catches declined through the 1970s and 1980s to the extent where no salmon were recorded in the late 1980s and early 1990s. This decline was probably due largely to the effects of agricultural pollution, which virtually extinguished the salmon stock of the River Axe. Water quality has subsequently improved, but has deteriorated again in recent years.

The report pays attention on the external consultation of the River Lyn Salmon Action Plan (SAP). This approach to salmon management within the England and Wales introduces the concept of river-specific Conservation Limits as a method of assessing the status of the salmon stock. The River Lyn Salmon Action Plan follows the format of those completed for the Rivers Exe, Axe, Avon & Erme, Teign, Torridge, Taw and Dart. It is the last of eight action plans that have been produced for salmon rivers within Devon Area. The River Lyn Salmon Action Plan contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The Lyn salmon stock is judged to be meeting its Conservation Limit. However, this assessment is uncertain as it is based on an estimate of rod exploitation rate, which in itself is also uncertain.

    Beschreibung: This is the Rivers Avon & Erme Salmon Action Plan Consultation document produced by the Environment Agency in 2003. This document is part of a national initiative to produce action plans for the management of all the main salmon rivers of England and Wales by 2003. The aim of this plan is (i) to assess the status of the salmon stocks and fisheries of the rivers Avon and Erme - including the use of Conservation Limits as part of this process, (ii) to identify factors which may limiting stock and fishery performance and (iii) to propose remedial measures address these factors. The report pays attention on the external consultation of the Rivers Avon & Erme Salmon Action Plan (SAP). While the stocks of both rivers have exceeded their respective conservation limits occasionally in individual years, only the Erme has achieved a period of statistical compliance since 1993. It is possible that this situation is largely normal, due to the steep nature of the rivers, obstructions to migration and dependence on suitable flow conditions occurring at the right time of year. The decline of the spring-running component of the stocks has left the populations dependent on autumn flows for the success of the late running component. Actions required to improve compliance with Conservation Limits are proposed and prioritised. The urgent actions relate to the need to improve the consistency with which adequate numbers of salmon reach and utilise fully all the accessible areas of the river systems. This document is intended to be dynamic, with opportunities for review occurring at regular intervals. For example, as the science of fisheries management improves, particularly in the setting of Conservation Limits, so the targets may be altered to reflect any improved methodology.

    Beschreibung: 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.

    Beschreibung: This is the River Exe Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Exe 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 Exe SAP follows the format of those completed for the Rivers Teign, Torridge, Taw and Dart. It is the fifth of eight action plans that will be produced for salmon rivers within Devon Area. The River Exe SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The Exe salmon stock is judged to be meeting its Conservation Limit. However, this assessment is uncertain as it is based on an estimate of rod exploitation rate, which in itself is also uncertain. At present there is no means of accurately assessing the River Exe salmon run. In common with many other rivers, estimation of stock using catch statistics and rod exploitation rate is the model used, when direct assessment is not possible. The installation of a fish counter on the lower river, or the use of other direct counting methods, would help to provide a direct assessment of the annual run of salmon into the river. This would improve our ability to estimate the spawning escapement and hence assess compliance with the Conservation Limit.

    Beschreibung: This is the River Teign Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Teign Salmon Action Plan (SAP). This approach to salmon management within the England and Wales introduces the concept of river-specific Conservation Limits as a method of assessing the status of the salmon stock. The River Teign Salmon Action Plan follows the format of those completed for the Rivers Torridge, Taw and Dart. It is the fourth of eight action plans that will be produced for salmon rivers within the Devon Area Fisheries, Recreation and Biodiversity Team. The River Teign SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The Teign salmon stock is currently failing to meet its conservation limit. This failure is largely attributed to the reduction in the survival rate during the marine phase of the salmon life cycle. This is likely to constrain stocks to lower levels than have existed historically. Still further catch controls may contribute to a reduction in exploitation rates and allow stocks to recover to meet their conservation limit. Other important actions include the continuation of habitat improvement works which aim to maximise spawning habitat utilisation, spawning success, and juvenile survival and production.

    Beschreibung: This is the River Torridge Salmon Action Plan Final document produced by the Environment Agency in 2000. This final Salmon Action Plan (SAP) for the River Torridge catchment has been produced after consideration of feedback from external consultation. The SAP provides a list of the issues and actions which were agreed for a five-year programme to maintain and improve the River Torridge salmon stock. Some of these actions have already been delivered before finalising the SAP, but others have yet to be addressed. An attempt has been made to estimate the cost of the actions, identify possible sources of funding and the timescale under which they will be dealt with. The Torridge salmon stock has declined dramatically since the 1960s and is currently failing to meet the spawning target. The decline in the spring fish component has accounted largely for the overall decrease in stocks. The reasons for the decline are not fully understood, but the spring fish problem is recognised as a national issue. The rate of survival over the marine phase has reduced in recent years for both the grilse and multi-sea winter (MSW) components. This is undoubtedly a contributory factor, which may now constrain stocks to lower levels than have existed historically. Agricultural pollution is recognised as one of the main factors limiting freshwater production. This SAP aims to promote long term collaboration between the Agency and other interested parties in managing the River Torridge salmon stock and fisheries.

    Beschreibung: This is the Coleopteran Fauna of ERS on the river Dane, Cheshire: a survey report produced by the Environment Agency in 2003. A comprehensive survey of the Exposed Riverine Sediment (ERS) on the River Dane, Cheshire was undertaken between mid-April and mid-June 2003. 6 locations were selected and subsequently examined to determine the importance of the constituent invertebrate fauna. Appropriate sampling techniques (i.e. pitfall trapping, hand searching and excavations) were directed towards the target group (Coleoptera). All adults from the chosen taxa were identified to species level. The relative value of the fauna was assessed using species richness, conservation status, fidelity score and a site quality index.

    Beschreibung: This is the Visual survey ERS Dane, Weaver & Bollin Catchments produced by the Environment Agency in 2005. Visual surveys of the River Dane downstream of the confluence with the Swettenham Brook, the River Weaver, and the River Bollin catchment in the EA Northwest South area of England were undertaken between 3rd and 9th February 2005 with the aim of identifying the spatial distribution and relative quality of exposed Riverine sediments (ERS). The potential value of these ERS in terms of likely habitat quality for ERS invertebrate communities was determined by recording a suite of appropriate environmental variables. Following an initial cartographical analysis of reaches likely to contain ERS, tens of kilometres of riverbank were inspected and 67 areas of ERS were selected for detailed visual survey. Site characteristics ranged widely both between and within catchments, with habitat quality ranging from poor to very high.

    Beschreibung: 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.

This final Salmon Action Plan (SAP) for the River Camel 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 Camel 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. This Action Plan aims to promote long term collaboration and co-operation between the Agency and other interested parties to effectively and efficiently manage the stock of salmon on the River Camel.

    Beschreibung: This is the Proposed Environmental Quality Standards (EQS) for Phenol in Water prepared for the National Rivers Authority, and published by the Environment Agency in 1995. The report reviews the properties and uses of phenol, its fate, behaviour and reported concentrations in the environment and critically assesses the available data on its toxicity and bioaccumulation. The information is used to derive EQSs for the protection of fresh and saltwater life and for the abstraction of water to potable supply. Phenol is widely used as a chemical intermediate and the main sources for phenol in the environment are of anthropogenic origin. Phenol may also be formed during natural decomposition of organic material. The persistence of phenol in the aquatic environment is low with biodegradation being the main degradation process (half-lives of hours to days). Phenol is moderately toxic to aquatic organisms and its potential to bioaccumulate in aquatic organisms is low.

    Beschreibung: This is the Stillwaters monitoring programme summary results 2000 from the Environment Agency. 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. During 2000, stillwaters monitored for the fourth year of the Stillwaters Monitoring Programme were Hatch Mere, Marbury Big Mere, Comber Mere, Tabley Mere, Tatton Mere and Melchett Mere. Algal, zooplankton and water chemical samples were taken on all meres. Surveys of Tabley Mere and Comber Mere continued on from last year when water quality concerns were highlighted. Continuous monitoring in Oak Mere, including water level data continued in 2000. Fish surveys were carried out in Tatton Mere and Comber Mere. Tabley Mere survey was abandoned due to the awkward bathymetry of the mere. No invertebrate samples were taken in 2000 due to lack of resources.

    Beschreibung: This is the Proposed Environmental Quality Standards (EQS) for Nonylphenol in Water produced by the Environment Agency in 1997. The report reviews the properties and uses of Nonylphenol, its fate, behaviour and reported concentrations in the environment, and critically assesses available data on its toxicity and bioaccumulation. The information is used to derive EQSs for the protection of fresh and saltwater life as well as for water abstracted to potable supply.Nonylphenol (NP) is used extensively in the production of other substances such as non-ionic ethoxylate surfactants. It is through the incomplete anaerobic biodegradation of these surfactants that most nonylphenol reaches the aquatic environment in effluents, e.g. from sewage treatment works and certain manufacturing operations. It was explicitly stated by the Environment Agency that the EQS was to be derived for NP and not Nonylphenol ethoxylates. However, since NP is unlikely to be present in the aquatic environment in the absence of other nonylphenol ethoxylate (NPE) degradation by-products, the toxicity, fate and behaviour of some of these (i.e. nonylphenol mono- and diethoxylates (NP1EO and NP2EO), mono- and di-nonylphenoxy carboxylic acids (NP1EC and NP2EC) have also been considered in this report. In the aquatic environment and during sewage treatment, NPEs are rapidly degraded to NP under aerobic conditions. NP may then be either fully mineralised or may be adsorbed to sediments. Since NP cannot be biodegraded under anaerobic conditions it can accumulate in sediments to high concentrations.

    Beschreibung: This is the Impact Assessment of ionising Radiation on Wildlife document produced by the Environment Agency in 2001. This report describes the behaviour and transport of radionuclides in the environment, considers the impact of ionising radiation on wildlife, and makes recommendations on an approach for the Impact assessment of ionising radiation on wildlife for England and Wales. The assessment approach focuses on three ecosystems representative of those considered potentially most at risk from the impact of authorised radioactive discharges, namely a coastal grassland (terrestrial ecosystem); estuarine and freshwater ecosystems. The likely scale of the impact on wildlife is also assessed in light of a preliminary analysis based on this assessment approach. The report demonstrates the behaviour and transfer of radionuclides in a number of different ecosystem types. Particular emphasis is placed on exposure pathways in those ecosystems most likely to be impacted by the authorised discharges of radioactivity within England and Wales. The use of biomarker techniques is reviewed in the report, and their application to the study of exposure to multiple contaminants is discussed.

    Beschreibung: This is the report on Habitats Directive, the Review of Consents Stage 1 and 2 by the Environment Agency of the Rochdale Canal cSAC.The Habitats Directive has the main aim to promote the maintenance of biodiversity by defining a common framework for the conservation of wild plants and animals and habitats of community interest. The Directive establishes a European ecological network known as "Natura 2000". The network comprises Special Areas of Conservation (SAC) and Special Protection Areas (SPA). In the section on Stage 1 or Screening Process of the Habitat Directive, it is identified the likely impacts upon the Rochdale Canal of a project, plan or activities, either alone or in combination with other projects, plans or activities, and considers whether these impacts are likely to be significant. In the section on Stage 2 or Appropiate Assessment of the Habitat Directive, it is considered the impact on the integrity of the Rochdale Canal of the projects, plans or activities, either alone or in combination with other projects, plans or activities, with respect to the site’s structure and function and its conservation objectives. Additionally, where these are adverse impacts, an assessment of the potential mitigation of those impacts. The criteria used in this report to identify relevant projects, plans or activities and their impacts are water quality discharge consents, waste management licences, abstraction licences, Integration Pollution Control (IPC) and Integrated Pollution Prevention Control (IPPC) permits.

    Beschreibung: This is the River habitat survey and geomorphological evaluation of the Glaze Brook Catchment report produced by the Environmental Research and Consultancy of the University of Liverpool in 2002. The major aims of the project were to provide baseline information on river habitats in the Glaze catchment using standard River Habitat Survey (RHS) methods (sampling 25% of the catchment length) and, through the geomorphological audit, to assess the distribution and intensity of geomorphological processes, notably sediment transfer, sources and sinks. This information was then used to develop informed management recommendations. The Glaze catchment is a heavily modified watercourse of generally poor habitat quality. The most important factors contributing to the low quality of the sites are poor bank and channel features; low diversity/absence of channel vegetation; paucity of bankside trees and, to a lesser extent, a lack of channel substrate diversity. The high degree of modification relates principally to extensively resectioned banks and channels plus extensive culverting in the urban parts of the catchment.

    Beschreibung: This is the River Axe Salmon Action Plan Final document produced by the Environment Agency in 2004. The River Axe Salmon Action Plan (SAP) has been produced after consideration of feedback from public consultation. The final plan provides a list of the agreed issues and actions for the next five years to maintain and improve the salmon stock of the River Axe. Efforts have been made to identify possible sources of funding, partners and timescales. It indicates how the plan will be managed, including the process for reviewing stock status, issues, actions and progress. Low marine survival is currently a major factor limiting salmon stocks throughout the United Kingdom. However, on the River Axe the freshwater environment is still the main factor limiting the recovery of the salmon stock. Most of the adults returning to the Axe at present are probably derived from hatchery reared smolts, although there has been some natural reproduction in recent years. Juvenile populations in the Yarty indicate that this is a tributary where salmon have started to re-establish a self-sustaining population. Actions to improve the quality of the freshwater environment, both in terms of water quality and sedimentation, are seen as the top priorities, and are required to allow the Axe to support a self-sustaining salmon population.

    Beschreibung: This is the River Dart Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Dart 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 north of the River Dart catchment is included in the Dartmoor candidate Special Area of Conservation (cSAC), designated under the Council EC Directive 92/43/EEC, the “Habitats Directive”. One of the conservation objectives for the cSAC is to maintain the habitat for Atlantic Salmon, Salmo Salar in favourable condition. The River Dart is an important salmon, sea trout and brown trout fishery with no significant coarse fishery. However, eels are ubiquitous throughout the catchment and are lightly exploited. The River Dart SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery.

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.

    Beschreibung: 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.

    Beschreibung: In February 1996, the National Salmon Management Strategy was launched by the Environment Agency's predecessor the National Rivers Authority (NRA, 1996).The strategy concentrates on four main objectives for the management of salmon fisheries in Englandand Wales. These are primarily aimed at securing the well being of the stock, but in doing so willimprove catches and the associated economic returns to the fisheries. The four main objectives are :(i) Optimise the number of salmon returning to home water fisheries,(ii) Maintain and improve fitness and diversity of salmon stocks.(Hi) Optimise the total economic value of surplus stocks,(iv) Ensure necessary costs are met by beneficiaries

    Beschreibung: The following brief is to ensure standard criteria and format are used for the scoping and environmental assessment of water resources projects leading to the production of an environmental report or Environmental Statement. This volume is one of a series giving guidance on water resources projects. The water resources projects will predominantly comprise drought orders and permits,time limited and permanent licences. Smaller projects, such as spray irrigation licences, will not require an environmental assessment. This document forms the basis fordiscussions between the Environment Agency North East Region, consultees and the applicant. The process aims to produce a thorough assessment. Each section addresses consecutive elements of the assessment process. Section 2outlines the structure for a scoping document, section 3 outlines the structure for an Environmental Statement and section 4 gives guidance on the role of an EnvironmentalAction Plan. Appendices 1 and 2 should be used in conjunction with the scoping process and cover awide range of aspects. However, some projects may not require all of them to be included, whilst for others, the inclusion of additional factors may be appropriate.

    Beschreibung: This is the report on Habitats Directive, the Review of Consents Stage 1 and 2 by the Environment Agency of the West Midlands Mosses cSAC, Wybunbury Moss and Abbots Moss.The Habitats Directive has the main aim to promote the maintenance of biodiversity by defining a common framework for the conservation of wild plants and animals and habitats of community interest. The Directive establishes a European ecological network known as "Natura 2000". The network comprises Special Areas of Conservation (SAC) and Special Protection Areas (SPA). In the section on Stage 1 or Screening Process of the Habitat Directive, it is identified the likely impacts upon the West Midlands Mosses cSAC, Wybunbury Moss and Abbots Moss of a project, plan or activities, either alone or in combination with other projects, plans or activities, and considers whether these impacts are likely to be significant. In the section on Stage 2 or Appropiate Assessment of the Habitat Directive, it is considered the impact on the integrity of the West Midlands Mosses cSAC, Wybunbury Moss and Abbots Moss of the projects, plans or activities, either alone or in combination with other projects, plans or activities, with respect to the site’s structure and function and its conservation objectives. Additionally, where these are adverse impacts, an assessment of the potential mitigation of those impacts. The criteria used in this report to identify relevant projects, plans or activities and their impacts are water quality discharge consents, waste management licences, abstraction licences, Integration Pollution Control (IPC) and Integrated Pollution Prevention Control (IPPC) permits. Proformas, hydrogeological and GIS maps are included in the review.

    Beschreibung: This is the River Gowy and Thornton Brook improvements: Environmental Action Plan report produced by the Environment Agency in 2000. This Environmental Action Plan relates to the proposals by the Environment Agency to improve the flood defences of land adjacent to the River Gowy, about 3 km east of Ellesmere Port, Cheshire. The purpose of the Environmental Action Plan (EAP) is to provide details of how the issues addressed in the Environmental Statement (ES) will be carried through to the completion of the project. The EAP represents a commitment to the environmental recommendations formulated during the environmental assessment process and should be closely adhered to during the design, construction and post project monitoring o f the works. For any matters that cannot be finalised until during construction the constraints will be detailed in the plan so they are implemented in the contracts.

    Beschreibung: This report presents a preliminary assessment of the state of salmon stocks and fisheries in England and Wales in 2001 to assist ICES in providing scientific advice to NASCO and to provide early feedback to fishery managers and anglers. The chief indicators of the state o f salmon stocks are normally the catches taken by rod and net fisheries. However, in 2001 angling was affected by the outbreak of foot and mouth disease (FMD), which restricted angling opportunities and access to rod fisheries in many parts of the country for lengthy periods. It is impossible to quantify the impact that FMD had on rod catches, although these were undoubtedly significantly reduced; net fisheries were unaffected by FMD. The declared salmon catch for 2001 (including those fish released alive by anglers) is provisionally estimated at 209 tonnes, representing some 57,000 fish, and comprising 153 tonnes (-43,000 fish) by nets and fixed engines and 56 tonnes (-14,000 fish) by rods. For direct comparison with previous years, it should be noted that the declared catch prior to the issue of a second reminder was about 49 tonnes (see below). An estimated 26 tonnes (43%) of the rod catch was released alive. These figures do not take account of catches of salmon which go unreported (including those taken illegally), and it is estimated that there may have been a total of 33 tonnes of additional fish caught in 2001; approximately 15% of all fish killed.

    Beschreibung: This is the River Exe Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Exe catchment has been produced after consideration of feedback from external consultation. The actions presented within this Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. An attempt has been made to cost these actions, identify possible sources of funding and to provide a timescale for action. This SAP aims also to promote long term collaboration between the Agency and other interested parties in managing the River Exe salmon stock and fisheries. The River Exe salmon population is currently judged to be passing its Conservation Limit. However, its apparent declining trend in egg deposition in the recent years and the high uncertainty in its stock assessment suggest the following actions as priorities: actions promoting good land management, maximising salmon natural spawning activity and protecting smolts throughout the Exe catchment. Also, the lack of information on salmon stocks and its habitat quality and availability is recognised as the main factor limiting the better management of salmon fisheries. The actions presented in this document are perceived as those required to address the important issues and factors limiting the salmon stock.

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.

    Beschreibung: This is the River Taw Salmon Action Plan Final document produced by the Environment Agency in 2000. This final Salmon Action Plan (SAP) for the River Taw catchment has been produced after consideration of feedback from external consultation. The SAP provides a list of the issues and actions which were agreed for a five-year programme to maintain and improve the River Taw salmon stock. Some of these actions have already been delivered before finalising the SAP, but others have yet to be addressed. An attempt has been made to estimate the cost of the actions, identify possible sources of funding and the timescale under which they will be dealt with. The Taw salmon stock is currently failing to meet its spawning target. However, there was a period of compliance in the 1990s following a decade of failure through the 1980s. The freshwater environment of the Taw has improved in recent years. The actions presented in this SAP are perceived as those that are required to address, as far as possible, the important issues and factors currently limiting the salmon stock on the river. This SAP aims to promote long term collaboration between the Agency and other interested parties in managing the River Taw salmon stock and fisheries.

    Beschreibung: This is the River Tavy Salmon Action Plan Consultation document produced by the Environment Agency in 1999. The report pays attention on the external consultation of the River Tavy 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. In addition, salmon action plans have for the first time, attempted to evaluate in economic terms, all of the contributory components of the salmon fishery. The River Tavy Salmon Action Plan follows that for the River Tamar and River Lynher and is the third of seven action plans that will be produced for salmon rivers managed by the Cornwall Area FER department. The River Tavy SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery.

    Beschreibung: 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.

    Beschreibung: This is the River Dart Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Dart 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 Dart salmon stock. The low marine survival (likely to be below 10%) is possibly to be the main cause for the River Dart salmon stock non-compliance with its conservation limit. Actions protecting smolts and maximising spawning activity of returning adults are seen as priorities to contribute to mitigate the low marine survival. Also the lack of information on salmon stock and its habitat is recognised as one main factor limiting the better management of salmon fisheries. Efforts will be focused on gaining more knowledge and improving modelling techniques. The actions presented in this document are perceived as those required to address the important issues and factors limiting the salmon stock. This SAP aims also to promote long term collaboration between the Agency and other interested parties in managing the River Dart salmon stock and fisheries.

The report pays attention on the external consultation of the River Yealm 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 Yealm Salmon Action Plan follows the format of those completed for the rivers Tamar, Lynher, Tavy, Camel, Fowey and Plym. It is the final one of seven action plans that will be produced for salmon rivers managed by Cornwall Area. The River Yealm 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 potable water abstractions in the headwaters, workings for china clay on the main tributary, two inert waste landfill sites and an aggregate quarry adjacent to the main river and inputs from several Sewage Treatment Works (STW) and two industrial estates. The main River Yealm has been designated as River Ecosystem Class 1 for its water quality objectives. This is the highest water quality target set for rivers.

    Beschreibung: This is the Rivers Avon & Erme Salmon Action Plan Final document produced by the Environment Agency in 2004. The Rivers Avon and Erme Salmon Action Plan (SAP) has been produced after consideration of feedback from public consultation. The final plan provides a list of the agreed issues and actions for the next five years to maintain and improve the salmon stocks and fisheries of both rivers. Efforts have been made to identify possible sources of funding, partners and timescales. It indicates how the plan will be managed, including the process for reviewing stock status, issues, actions and progress. Low marine survival is currently a major factor limiting the numbers of salmon returning to spawn in both the Avon and the Erme. Actions to improve the accessibility of spawning areas and to maximise the productivity of spawning and nursery habitats are seen as priorities, which should help to offset the low marine survival. The quality of the information available to assess salmon stocks is recognised as a limiting factor in the management of salmon fisheries. The SAP aims also to promote long term collaboration between the Agency and other interested parties in managing the salmon stocks and fisheries of the Avon and the Erme.

    Beschreibung: This is the River Taw Salmon Action Plan Consultation document produced by the Environment Agency in 2000. The report pays attention on the external consultation of the River Taw Salmon Action Plan (SAP). This approach to salmon management within the England and Wales introduces the concept of river-specific Conservation Limits as a method of assessing the status of the salmon stock. The River Taw Salmon Action Plan (SAP) includes a description of the current status of the rod and net fisheries and historical trends. The Taw salmon stock has declined since the 1960s and is currently failing to meet the spawning target. The decline in the spring fish component has accounted largely for the overall decrease in stocks. The reasons for the decline are unclear, but the spring fish problem is recognised as a national issue. The rate of survival over the marine phase has reduced in recent years for both the grilse and MSW components. This is undoubtedly a contributory factor, which may now constrain stocks to lower levels than have existed historically.

    Beschreibung: This is the Species management in aquatic Habitats overview of sub projects and their management produced by the Environment Agency in 1998. This report was under the R&D Project, which it was initiated in 1995 to provide information on species of conservation value of particular relevance to the Environment Agency (then the National Rivers Authority, NRA), in relation to its activities affecting aquatic environments. Outputs comprise Species Action Plans (SAPs), practical management guidelines for Agency staff and third parties, and various research and survey outputs to improve the knowledge base on the status and ecological requirements of priority species. This R&D Technical Report provides an overview of the work undertaken, additionally identifying lessons to be learnt in the management of species-related research within the framework of the UK Biodiversity Action Plan. The process of species selection was initially based upon a wide ranging review of priority species of relevance to the then NRA, encompassing both highly threatened species and species that are relatively common but are at particular risk from Agency activities.

    Beschreibung: This is the Species management in aquatic Habitats WRc Interim 1997 document produced by the Environment Agency in 1997. This document reports progress on R&D Project 640, which aims to provide information on species of conservation value of particular relevance to the Environment Agency, in relation to its activities affecting aquatic environments. A range of stand-alone outputs is being produced, comprising Species Action Plans, practical management guidelines for Agency staff and third parties, and various research outputs to improve the knowledge base on the status and ecological requirements of priority species. The species of conservation values are: water shrew, daubenton’s bat, Kingfisher, yellow wagtail, Grey wagtail, sand martin, reed bunting, dipper, marsh warbler, great crested new, spined loach, brook lamprey, river lamprey, sea lamprey, shining rams-horn snail, little whirlpool rams-horn snail, depressed river mussel, a freshwater pea mussel, native crayfish, and triangular club-rush. The process of species selection was altered during the course of the project by the report on biodiversity by the UK Biodiversity Steering Group (1995). Whilst still including species that were not particularly endangered but were greatly influenced by the activities of the Agency, the project addressed species on the ‘short’ and ‘middle’ priority lists of the Biodiversity report, particularly those for which the Agency had specific responsibilities.

    Beschreibung: This is the Habitats regulations for stage 3 assessments: radioactive substances authorisations report from the Environment Agency, published on October 2003. The report focuses on the stage 3 assessments of radioactive substances authorisations in UK (to take place over the next five years, starting in 2003), which may have a potential impact on European designated Natura 2000 sites such Special Protection Areas (SPA), Special Areas of Conservation (SAC); and thus require further detailed assessment. This Environment Agency R&D project was commissioned to ERC, University o f Liverpool, in conjunction with Westlakes Scientific Consulting and the Centre for Ecology and Hydrology, as part o f the agency's preparation for the Stage 3 Assessments o f radioactive substances authorisations. The aim was to prepare site information sheets containing all data relevant for individual Natura 2000 sites needing Stage 3 Assessment and to stylise and represent species that require protection under the Habitats Regulations by the reference organism geometries listed in R&D Publication 128 (Copplestone et al., 2001).

    Beschreibung: This is the Effect of water quality on coarse fish productivity and movement in the Lower River Irwell and Upper Manchester Ship Canal: a watercourse recovering from historical pollution report produced by the Environment Agency in 2003. The aim of this study was to investigate the impact of water quality upon coarse fish population dynamics in a lowland, urban watercourse. All of the research carried was undertaken in the lower River Irwell and upper Manchester Ship Canal, between February 1998 and December 2001. Of particular interest was the natural sustainability of the urban fishery given recent concern raised in the angling community over an apparent decline in coarse fish populations in lowland rivers. The research described in this report has concentrated upon the role of water quality in determining coarse fish population dynamics, and in particular: The impact of water quality upon fish growth and productivity; The impact of poor water quality and low dissolved oxygen concentrations upon fish distribution and movement; The impact of water quality upon the sexual development of fish.

    Beschreibung: 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.)

    Beschreibung: 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)

    Beschreibung: 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.)

    Beschreibung: 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.)

    Beschreibung: This report amplifies and refines some of the data alreadyissued covering the water resources of Volusia County, which were published asReport of Investigations No. 21. The work in the report was accomplished as acooperative program between the Department of Natural Resources, the U. S.Geological Survey and the Board of County Commissioners of Volusia County.Volusia County is almost totally dependent upon the water which falls upon thecounty and has a recharge area contained along the western portion and thecentral portions of the county. Excellent water is produced in the areal rechargeand it is anticipated that this data will expand the existing knowledge of thewater resources to permit the development of a great capacity for existingutilities and to offset and solve some of the problems now in the area.

    Beschreibung: The Biscayne Aquifer is the principal source of water for the heavilypopulated area in the vicinity of West Palm Beach and Miami. Thepublication of this data is timely and will assist in the intelligent developmentof the water resources of the area.The report recognizes two major aquifers as the source of groundwater in Collier County. The lower aquifer is highly mineralized, butcontains usable water, and the more shallow aquifer is the source oflarge supplies, which are utilized by municipalities and domestic users.Adequate supplies of fresh water are present in the Naples area and byproper planning, these can be developed in an orderly manner and saltwater encroachment can be prevented.(PDF has 99 pages)

    Beschreibung: 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)

    Beschreibung: 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.)

    Beschreibung: 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.)

    Beschreibung: 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.

    Beschreibung: 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.)

    Beschreibung: Because the Stuart area is, at times, surrounded on threesides by saline water, the underlying fresh-water aquifer isvulnerable to salt-water encroachment. With progressivelylarger withdrawals of ground water for public and privatesupplies, the possibility of salt-water contamination of freshwatersupplies is increased. (PDF contains 51 pages.)

    Beschreibung: In December 1956 the U. S. Geological Survey, in cooperationwith the Florida Geological Survey and the Board ofCounty Commissioners of Pinellas County, collected waterleveland chloride content of water in 94 wells in PinellasCounty. 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.

    Beschreibung: 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.)

    Beschreibung: 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.

    Beschreibung: 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.)

    Beschreibung: 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)

    Beschreibung: 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.)
