AWB Artificial Water Body - A man-made surface water body, rather than a modified natural water body, which supports important aquatic ecosystems. It includes and some man-made reservoirs.

CAMS Catchment Abstraction Management Strategies

CIP Catchment Implementation Plan

Classification Method for distinguishing the environmental condition or “status” of water bodies and putting them into one category or another e.g. good or moderate ecological status.

Diffuse source Pollution resulting from scattering or dispersed sources that are collectively significant but to which effects normally difficult to attribute individually.

EA

Element A feature of an aquatic (surface water) ecosystem that can be described as a number to give a classification. A biological element is a collective term for a particular characteristic group of animals or plants present in an aquatic ecosystem (for example phytoplankton; benthic invertebrates; phytobenthos; macrophytes; macroalgae; angiosperms; fish).

Eutrophication ‘Eutrophication’ is the process whereby excessive nutrients, especially nitrogen and phosphorus compounds, cause an accelerated growth of algae and plants. This growth affects water quality and the balance of organisms such as fish. High phosphorus concentrations are the main cause of eutrophication in fresh waters. ftRBMP First Thames River Basin Management Plan

GES Good Ecological Status - The objective for a surface water body to have biological, structural and chemical characteristics similar to those expected under nearly undisturbed conditions.

GEP Good Ecological Potential - Those surface waters which are identified as Heavily Modified Water Bodies and Artificial Water Bodies must achieve ‘good ecological potential’. Good potential is a recognition that changes to morphology may make good ecological status very difficult to meet. In the first cycle of river

Loddon Catchment Implementation Plan Page 3 19/03/2012

basin planning good potential may be defined in relation to the mitigation measures required to achieve it and a willingness to pay for those measures.

HMWB Heavily Modified Water Body - A surface water body that does not achieve good ecological status because of substantial changes to its physical character resulting from physical alterations caused by human use, and which has been designated, in accordance with criteria specified in the Water Framework Directive, as ‘heavily modified’.

Hydromorphology Describes the hydrological and geomorphological processes and attributes of surface water bodies. For rivers, hydromorphology describes the form and function of the channel as well as its connectivity (up and downstream and with groundwater) and flow regime. This defines its ability to allow migration of aquatic organisms and maintain natural continuity of sediment transport throughout the fluvial system. The Water Framework Directive requires surface waters to be managed in such a way as to safeguard their hydrology and geomorphology so that ecology is protected.

Phosphates Phosphorus in our river comes from a number of sources including treated sewage effluent and agriculture. P is essential for plant growth but at higher levels can lead to eutrophication and a change to the river's ecology.

Point source Pollution arising from an identifiable and localised area, structure or facility, such as a discharge pipe or landfill.

Sediment The term sediment refers to anything that is not dissolved or in solution and which can be removed by filtration or settlement. The term includes solids that are floating on top, or suspended within the water. Phosphate is often associated with sediment as it is bound to the soil (unlike nitrates, which are more soluble).

STW Sewage Treatment Works

WB Water Body - A manageable unit of surface water, being the whole (or part) of a stream, river or canal, lake or reservoir, transitional water (estuary) or stretch of coastal water. A ‘body of groundwater’ is a distinct volume of groundwater within an aquifer or aquifers.

WFD Water Framework Directive - European Union legislation (2000/60/EC) establishing a framework for European Community action in the field of water policy.

1 Introduction This plan presents a prioritised programme of actions to achieve Good Ecological Status (GES) or in the case of heavily modified waterbodies, Good Ecological Potential (GEP) for the Loddon catchment. It builds on the First Thames River Basin Management Plan (ftRBMP) published in December 2009 for meeting the requirements of the EU Water Framework Directive. River Basin Management Plans (RBMPs) are strategic documents setting out what will occur in river basins. RBMPs set out in general terms how the water environment will be managed. They provide a framework for more detailed decisions to be made. RBMPs are based on cycles of planning and action reviewed every six years. There will be three planning and action cycles which are: • 1st cycle - 2009 to 2015; • 2nd cycle - 2015 to 2021; and • 3rd cycle - 2021 to 2027. We are currently in the 1st cycle. All the actions described in this document are for delivery during this period. River basin planning requires integration across four planning scales: National (both and Wales), River Basin District, Catchment and Waterbody (Local). The Environment Agency (EA) is working with individuals and organisations at all these levels to ensure that information and decisions taken at one level inform planning at another. The ftRBMP is a strategic document. As such, it does not contain all of the waterbody specific actions (details) and investigations that will be needed to deliver at the catchment scale. There is therefore a need to produce Catchment Implementation Plans (CIPs) to enable both EA and external partners to continue to engage actively with the WFD process and undertake the work needed to get achieve GES/GEP in the Loddon catchment. This CIP sets out how the EA and its local delivery partners will achieve GES/GEP for the Loddon catchment. It outlines the main areas of work that will be undertaken during the 1st planning cycle for the Loddon catchment.

Key objectives for this Catchment Implementation Plan are to: 1. Act as a tool and evidence base to assist delivery of good ecological status and avoid deterioration of waterbodies; 2. Provide a working document to engage partners to achieve actions to improve water environments; 3. Classify status of water in the Loddon catchment and set out ways to improve confidence in our data.

Some of the actions listed may require significant investment and resource. The availability of funding and therefore investigation into the reasons for failure will be a high priority. Once understood this will provide the justification for further actions and associated costs. This CIP will be a key tool for EA managers, operational staff and external stakeholders for steering this investment. In addition to help guiding our own resources, a prioritised list of water bodies will help our co-deliverers focus on the same areas, allowing for a more co-ordinated approach. The prioristation is consistent across the Thames river basin.The EA’s priorities for the Loddon catchment are shown in Table 1.

The criteria is outlined below.

Loddon Catchment Implementation Plan Page 6 19/03/2012

1.1 Our commitment

• Those water bodies we predicted to be good ecological status or potential by 2015

• Those water bodies Failing Drinking Water Protected Area and/or Habitats Directive Protected Area Status

1.2 Confidence in our evidence

• Water bodies we are confident have an ecological failure and we understand the reasons why. Therefore, we are in a good position to progress improvement action

1.3 Failing Biology

• Those water bodies which have a bad or poor biological status

2 Loddon catchment summary

2.1 General Description The Loddon catchment is predominantly rural with urban areas primarily centred around the upper reaches. These include the towns of Basingstoke, Aldershot, Farnborough, Fleet. The lower Loddon borders south Reading and . The catchment contains: • 23 surface water bodies in total, of which there are: • 19 river waterbodies • 1 canal water body, and • 3 lake water bodies. • 10 groundwater bodies intersect the Loddon catchment

The upper reaches of the Loddon and tributaries Lyde and Whitewater are chalk streams. The catchment also features part of the , numerous gravel pits and lakes; 3 of these are designated lake water bodies. These are Mytchett Lake, Fleet Pond, Heath Lake shown in Figure 1. Continued development and its associated infrastructure, including the provision of drinking water and the treatment of waste water, represent further pressures on this water environment. Modification of these rivers, including dredging and installation of in-stream structures, has led to the loss of habitat diversity and the creation of barriers to upstream, downstream and lateral fish migration. The most significant pressures on classified water bodies may be summarised as follows: • Changes in physical river structure including for land drainage or flood defence purposes; • Physical barriers to fish migration; • Diffuse & point source pollution from urban run-off and roads • Nutrient enrichment from point and diffuse sources including discharges from sewage treatment works and agriculture

3 Water body information

3.1 Classification The majority of water bodies fail to meet good ecological status or potential. The Lyde is the only river water body in the catchment which currently achieves GES in the baseline data set. Mytchett Lake is the only lake water body in this catchment which currently achieves GES/GEP. These river waterbody classifications are based on the available monitoring data for the four WFD biological ‘elements’. These elements are fish, invertebrates, macrophytes and diatoms and a suite of water quality and chemical elements. Classification information for all water bodies and specific ecological and chemical elements are given in Appendix II. Seventeen river water bodies fail to meet GES/GEP. This is due to a failure in one or more of the following elements: • Fish • Invertebrates • Diatoms • Phosphorus concentrations There are also 6 groundwater bodies which are within or partly within this catchment, all of these of which are classified as Poor status.

3.2 Heavily Modified Water Bodies

The Loddon catchment contains ten water bodies designated as ‘artificial’ or ‘heavily modified’ (6* river, 1 canal, 3* lake see Appendix II for list). This is because they may have been created or modified for a particular use such as flood protection, navigation or urban infrastructure. By definition, artificial and heavily modified water bodies are not able to achieve natural conditions. Instead the classification and objectives for these water bodies, and the biology they represent, are measured against ‘ecological potential’ rather than status. For an artificial or heavily modified water body to achieve good ecological potential, its chemistry must be good. In addition, any modifications to the structural or physical nature of the water body that cause damage to the biology must only be those essential for its valid use. All other such modifications to the water body must have been altered or managed to reduce or remove their adverse impact, these are called “Mitigation Measures”. This allows the potential for biology to be as close as possible to that of a similar natural water body. Often though, the biology will still be impacted and biological status of the water body may be less than good. Annex I: Designating artificial and heavily modified waterbodies: http://publications.environment-agency.gov.uk/pdf/GETH0910BSWJ-E-E.pdf * Subject to final confirmation

4 Actions At this stage, water bodies have been prioritised by the Environment Agency based on our confidence in the reasons for ecological failure. This prioritisation leads to the following activities; a) 'progress improvement action/action assessment',

Loddon Catchment Implementation Plan Page 11 19/03/2012 b) 'consider progressing improvement action/action assessment', and c) 'further monitoring and/or investigation required'.

Where we need to improve our confidence in a classification, we will undertake investigations to establish: 1) if it is failing – stage 1 investigation and, 2) the reason(s) for its failure – stage 2 investigation.

This prioritisation is based on available data and will be updated following further investigation.

A range of suspected and known reasons for failure of water bodies in this catchment have been identified by EA technical staff. The most common reasons for failure in the Loddon catchment are: • Changes in physical river structure including for land drainage, maintenance or flood defence purposes • Physical barriers to fish migration • Diffuse & point source pollution from urban run-off and roads • Nutrient enrichment from point and diffuse sources including discharges from sewage treatment works and agriculture

In the 1st plan cycle three types of actions will be undertaken in order to address suspected and known reasons for failure. These actions are discussed in more detail below.

4.1 Operational monitoring (2010-12) We will undertake operational monitoring where we have insufficient data to understand the problems or to identify the actions to solve them. Pursuing this information through this plan will result in a robust evidence base which will facilitate future planning and steer future investment. Targeted operational monitoring is planned for 11 river water bodies in this catchment and will be undertaken by the EA between 2010 and 2012 (see Appendix IV). Monitoring requirements will be reviewed again during 2012 for the 2nd planning cycle.

4.2 Investigations (2010-12) Investigations will be undertaken on 18 river water bodies in this catchment (see Appendix V). Initially, many of these will stage 1 to confirm failure of the ecological element (s) and then stage 2 to examine the possible reason (s) for failure. These investigations will vary from desk studies to bespoke monitoring and field work and will be undertaken during 2010 to 2012. The outcomes of these investigations will enable effective targeting of stage 3 improvement actions in future plan cycles.

4.3 Improvement actions (in place by 2012) Where the reasons for failure are understood improvement actions will be undertaken and targeted to address these pressures.

Loddon Catchment Implementation Plan Page 12 19/03/2012

4.3.1 ‘Day Job’ activities EA teams, through close working with external delivery partners, will continue to undertake a number of day job activities which are applicable to the majority of all water bodies in this catchment. These activities include: • Working with local landowners and delivery partners, and the provision of legislative and technical advice, to maintain and improve freshwater fisheries and biodiversity; • Targeted site visits to ensure that individuals/businesses are undertaking activities in accordance/compliance with regulations, the permitting process and/or good practice; and • Working with local authorities to promote sustainable drainage systems (SuDS) to improve water quality and maintain the function of floodplains. These activities will help to reduce environmental pressures in this catchment and contribute to ensuring there is no deterioration of water bodies.

4.3.2 Field actions In addition to ‘day job’ activities, there are a number of targeted actions underway or planned in the 1st plan cycle. These actions are called ‘field actions’ and will principally be undertaken on river water bodies to address known pressures causing failure to meet GES/GEP. Appendix VI provides a programme of specific field actions that will address reasons for failure in priority river water bodies.

5 Partners There are some existing partners below we are working with to deliver GES/GEP in the Loddon catchment. This list is not exhaustive. We are writing to parish councils and interested parties to identify a complete list of partners for this catchment work. These partners include: • Basingstoke Canal Authority • Borough Council • Basingstoke Water Cycle Study Group • Berks, Bucks and Oxon Wildlife Trust • Forest District Council • Blackwater Valley Countryside Partnership • Blackwater Valley Project • Countrywatch and Save Our Loddon Valley Environment • Cove Brook Greenway Group • Estate & land owners • Town Council • Fleet Pond Society • Friends of the Emm Brook • Guildford Borough Council • County Council • Hampshire and Isle of Wight Wildlife Trust

6 Sub catchments To help us get the most out of limited resources, we have reviewed the needs and opportunities in the Loddon catchment. This review is based on planned operational monitoring and investigations, priority water bodies for improvement action, delivery mechanisms and environmental outputs and outcomes. Our actions are targeted to 5 sub catchments: • Loddon • Whitewater • Emm Brook • Hart and Fleet Brook • Blackwater & Cove Brook A summary of these sub catchments, their water bodies, known and suspected reasons for failure and associated actions are given below. Water bodies not on this list are still important for environmental improvements and to ensure no deterioration in status.

6.1 River Loddon The River Loddon sub catchment (see Figure 2) contains 4 river water bodies, of which all are priority water bodies and 1 is heavily modified, as shown below in Table 2. Many of the river Loddon tributaries are very low gradient, low energy, rivers which have been historically altered for land drainage purposes. These tributaries present a particular challenge. They require careful consideration to achieve GES/GEP through physical habitat restoration, adjustments to maintenance activity whilst harmonising with meeting flood risk management and other beneficial objectives such as public access.

Loddon Catchment Implementation Plan Page 15 19/03/2012

6.1.1 What is failing

Based on the WFD monitoring information shown in Table 2, the main conclusions of this classification of ecological status are summarised as: • All of the priority water bodies are failing for fish and diatoms; • High phosphate concentrations are seen across most of the sub catchment; and • There is no macrophyte data for any of the water bodies and only diatom data.

6.1.2 Reasons for failure

Physical habitat degradation and effluent discharged from a major sewage treatment works (STW) at Basingstoke are key pressures impacting the main river Loddon. Many of the water bodies, especially those that are classified as heavily modified, have been subject to physical alteration including channel straightening, bank re-profiling and dredging for flood prevention, and drainage, as well as the creation of new channels for mills or irrigation. The lack of monitoring information for some biological elements is an issue, both for understanding the problems and for identifying the actions needed to deal with them. The EA will aim to address this through additional operational monitoring.

6.1.3 Field Actions

19 field actions have been identified for the Loddon priority water bodies which address: spatial planning, habitat enhancement and fish passage, non-native species, agricultural diffuse source pollution, and partnership working. Specifically 6 field actions have been identified and will be undertaken by the EA, Basingstoke & Deane Borough Council, planners and developers to address waste water infrastructure and ensure future development does not contribute to deterioration in the class of the water bodies. See Appendix V1 for more detail. We will also work with landowners, local authorities, Wildlife Trusts, angling clubs and the Loddon Fisheries and Conservation Consultative and University of Reading to undertake 10 habitat enhancement, restoration and fish passage field actions on the river Loddon. Delivery of these actions will improve fish passage, sediment transport, habitat and flow diversity. These actions have the potential to improve fish, macrophyte and invertebrate populations through improved ecosystem functioning. We will address diffuse source pollution from agriculture on the Loddon (Sherfield on Loddon to Swallowfield) through undertaking work with Natural England, local trusts and farmers to provide advice and guidance through targeted farming workshops and ensure catchment compliance. A partnership approach will be undertaken throughout the catchment to deliver these field actions and ensure greater value for money. A more detailed summary of field actions is provided in Appendix VI.

6.2 Emm Brook

The Emm Brook sub catchment contains 1 river water body, Emm Brook, GB106039023130; this is a priority water body. The Emm Brook is a heavily modified water body and is not currently classified as achieving GEP. Heath Lake water body is also contained within this sub-catchment (see Figure 3).

6.2.1 What is failing Based on the WFD monitoring information shown in Table 3, the main failures can be summarised as: • High phosphate concentrations are seen in the waterbody • The water is currently failing its mitigation measures assessment (for details see Annex B Thames River Basin Management Plan http://publications.environment- agency.gov.uk/PDF/GETH0910BSWC-E-E.pdf page 280-281

6.2.2 Reasons for failure Physical habitat degradation and effluent discharged from a major sewage treatment works (STW) at Easthampstead, Wokingham are key pressures impacting the Emm Brook. The Emm Brook, classified as heavily modified, has been subject to physical alteration including channel straightening, bank re-profiling and vegetation management for flood prevention, and drainage, as well as culverting and bank reinforcement for urbanisation.

6.2.3 Field Actions Four field actions have been identified for the Emm Brook priority water body which will address: spatial planning and habitat enhancement. Identified field actions will be undertaken by the EA, local authorities, planners and developers. These actions will address waste water infrastructure and in particular ensure future development does not contribute to deterioration in the class of the Emm Brook water body. Further investigations will be undertaken on the water body to establish habitat enhancement and fish passage opportunities.

Loddon Catchment Implementation Plan Page 18 19/03/2012

Environment Agency Fisheries and Biodiversity teams hope to obtain a fluvial audit for the Emm Brook, in order to better our understanding of the hydromorphological issues.

Figure 3 Emm Brook catchment showing WFD classification

6.3 Blackwater & Cove Brook The Blackwater and Cove sub catchment contains 4 river water bodies (See Figure 4 page 19), all of which are priority water bodies. The exception is Hawley to Whitewater confluence at Bramshill on the River Blackwater . Two of the water bodies are heavily modified and none are currently classified as achieving GES/GEP.

6.3.1 What is failing Based on the WFD monitoring information shown in Table 4, the main failures can be summarised as: • The priority water bodies are failing for fish and 50% are failing for inverts;

Loddon Catchment Implementation Plan Page 19 19/03/2012

• High phosphate concentrations are seen across most of the sub catchment.

There are some issues with the 2010 classification update for ‘fish’ on the Blackwater (Hawley to Whitewater confluence at Bramshill) water body. Extra data is likely to be used to supplement the final status result.

6.3.2 Reasons for failure Physical habitat modification, pollution from urban run-off and roads, leaking and misconnected sewers and effluent discharged from major sewage treatment works (STW) represent the main pressures impacting the Blackwater and Cove Brook water bodies. In particular, modification due to urbanisation and flood protection, high phosphate concentrations, and possibly other water quality pressures from non water industry and diffuse sources are impacting the Blackwater from Aldershot to Cove Brook confluence at Hawley Meadow. Similar multiple issues are impacting the Cove Brook. Although there are no physical barriers to fish migration there is a big influence on water quality from urban run-off and this is reflected in the biological data. We are currently investigating opportunities to restore physical habitat. The lack of monitoring information for some biological elements is an issue, both for understanding the problems and for identifying the actions needed to deal with them. The EA will aim to address this through additional operational monitoring on the priority Blackwater water bodies. Stage 1 and 2 investigations are planned for all of the Blackwater water bodies and the Cove Brook (see Appendix IV & V).

Loddon Catchment Implementation Plan Page 20 19/03/2012

6.3.3 Field Actions 13 field actions have been identified for the Blackwater and Cove priority water bodies which will address: spatial planning, habitat enhancement and fish passage, and non-agricultural diffuse source pollution. Two field actions have been identified and will be undertaken by the EA, local authorities, planners and developers to address waste water infrastructure and ensure future development does not contribute to deterioration in the class of the Blackwater in the water body Bramshill to River Loddon confluence at Swallowfield. Point source and diffuse source pollution be addressed by the EA through targeted work. This work will investigate industrial estates thought to be causing impact to failing water bodies on the Blackwater and Cove Brook. We will also work with the Highways Agency to minimise pollution run-off into the river Blackwater from the A331. We will also undertake 6 habitat enhancement and fish passage projects with the Blackwater Valley Countryside Partnership, Hanson Aggregates, local authorities, landowners and angling clubs in the Blackwater water bodies. The Blackwater water body Bramshill to River Loddon confluence at Swallowfield is a candidate to achieve GES if we address the fish passage and habitat pressure as phosphate is expected to improve to good status by 2015.

6.4 Whitewater The Whitewater sub catchment contains 1 river water body (See Figure 5). This is a priority water body for improvement action and is currently classified as failing to achieve GES due to failing fish status in the 2010 update. Macrophyte surveys are being undertaken to classify the Whitewater and will be updated into this plan by the end of 2012. Early indication of walkover surveys indicate diffuse pollution impacts on this water body.

6.4.1 What is failing Based on the WFD monitoring information shown in Table 5, the main failure can be summarised as: • Failing to achieve GES for fish

6.4.2 Reasons for failure Physical habitat and barriers to fish passage represent the main pressures on this water body. A major pressure on fish populations is the prevention of their free movement through catchments, to be able to feed, breed and flourish. Such barriers can take the form of a range of physical structures such as weirs, sluices, culverts and bridge aprons. The impounding effect of these structures also impedes sediment movement. This impounding promotes and leads to accretion of fine silts and reduces the natural diversity of river form, all of which can impact the ecological status. In addition to operational monitoring for fish and water quality elements the EA also plan to undertake stage 1 sediment and stage 2 fish investigations on the Whitewater (see Appendix IV & V).

6.4.3 Field Actions 7 field actions have been identified for the Whitewater which will primarily address habitat enhancement and fish passage. We will undertake projects in partnership with landowners, angling clubs, and the Hampshire and Isle of Wight Wildlife Trust to address fish passage at key structures and undertake restoration of habitat.

Loddon Catchment Implementation Plan Page 22 19/03/2012

South East Water is undertaking an options appraisal to address water resource issues in the upper catchment. These aim to protect water dependent features on the Fen SSSI and . This work will also help target effort and ensure projects deliver the best outcomes for the environment.

6.5 Hart and Fleet Brook The Fleet Brook and Hart sub catchment contains 3 river water bodies. See Figure 6. The Fleet Brook and Hart (Crondall to Elvetham) are both priority water bodies. The Fleet Brook is designated as a heavily modified water body. Fleet Pond lake water body is also contained within this sub-catchment. All of the water bodies are currently classified as failing to achieve GES/GEP.

6.5.1 What is failing Based on the WFD monitoring information shown in Table 6, the main failures can be summarised as: • All priority water bodies are failing for fish and one is failing for inverts and one for diatoms; • High phosphate concentrations are seen across most of the sub catchment;

6.5.2 Reasons for failure

Fine sediment and channel modification are thought to be the main pressures impacting the Hart and Fleet Brook water bodies. Potential sources of sediment in this sub catchment include agricultural run-off from the headwaters of the Hart, urban run-off from Fleet, and run-off from military training land upstream of Fleet Pond. Metals and many toxic organic compounds also tend to accumulate in sediments. This can result in reduced growth and reduced breeding success of animals such as invertebrates that are important sources of fish food. Other pressures include barriers to fish passage, unconfirmed hydrology issues, phosphate from private discharges, and phosphate from Fleet and Hartley Witney STW. The water body from Crondall to Elvetham is part of the EA network of surveillance monitoring sites which are providing information on long-term natural and

Loddon Catchment Implementation Plan Page 24 19/03/2012 anthropogenic trends. This water body, in addition to the Fleet Brook water body, will continue to be monitored for specific ecological and water quality elements. Monitoring requirements will be reviewed again in 2012. Stage 1 and 2 investigations are also planned for both the Hart water bodies and the Fleet Brook to address specific ecological and physio-chemical elements, sediment, and water resource issues (see Appendix IV & V).

6.5.3 Field Actions

Six field actions have been identified for the Hart and Fleet Brook priority water bodies which will address: spatial planning, habitat enhancement and fish passage, and non-agricultural diffuse source pollution. One field actions has been identified and will be undertaken by the EA, local authorities, planners and developers to ensure future development does not contribute to deterioration in the class of the water bodies. Improving the understanding of the sources of pollution and the processes affecting river ecology in the Fleet Brook and Hart (Crondall to Elvetham) priority water bodies will be essential. This is to ensure existing and future work programmes are properly targeted and that other elements of classification such as invertebrates and fish improve. We need to understand the water quality and water resource issues more fully through targeted investigations and field assessment work. This evidence will be required before targeting action and pressures associated with habitat and fish passage. Sediment is also an issue for which we have identified the need for more targeted investigation. The Hampshire and Isle of Wight Wildlife Trust are already undertaking some catchment walkover surveys, including monitoring to investigate the sediment/phosphate inputs on the river Hart, which will assist with the quick identification of the sources of sediment intrusion in the river. A Phase 2 project designed to restore Fleet Pond is also underway in a highly degraded (input & legacy of sedimentation) HMWB SSSI lake. Fleet Pond has limited submerged plants, poor fish populations & limited wetland habitats in public ownership. Solutions include dredging & sediment traps. Works required to meet Public Service Agreement target & objective to reach GEP. This project will be contributed to by a number of partner organisations including Natural England, Hart District Council, Friends of Fleet Pond and Johns Associates. Solutions include habitat creation, source control and sediment traps. Environment Agency Fisheries and Biodiversity teams hope to obtain a fluvial audit for the Hart, in order to better our understanding of the hydromorphological issues.

7 How to get involved We believe that the WFD Loddon Catchment Implementation Plan will help to ensure that the water environment is protected and enhanced for future generations. To make the Plan work we need help from locally based organisations and people. Some of the work are introduced in Annex VI already being carried out and/or proposed. If you know your local water bodies you might be able to help us deliver the CIP. We want to work with you to improve the Loddon catchment in your area. Please contact John Sutton [email protected] with your ideas to improve the ecological status of water in the Loddon catchment.
