Flow from this discharge affected a stretch of the Little Don River.<br /> <br /> The Coal Authority stepped in to construct a scheme to treat the mine water and control water levels and pressure, in order to prevent significant outbreaks of pollution which had occurred at this site in the past. The scheme comprises of two lagoons and a reed bed to remove iron from the water prior to it being discharged into the local watercourse. This scheme has significantly improved the water over 2.4km.<br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Little Don from Source to River Don<br /> }}<br /> {{Site<br /> |WFD water body code=GB104027057460<br /> |WFD water body name=Little Don from Source to River Don<br /> |Heavily modified water body=No<br /> |Protected species present=No<br /> |Invasive species present=No<br /> }}<br /> {{Project background}}<br /> {{Motivations<br /> |Physico-chemical quality elements=Coal mine water pollution<br /> }}<br /> {{Measures<br /> |Floodplain / River corridor=Reedbed creation, Creation of two infiltration lagoons, <br /> }}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>

Land use is largely agricultural, with woodland cover and several reclaimed open cast and landfill sites. A significant part of the catchment fails the Water Framework Directive for fish, due to the cumulative effects of barriers to the upstream and downstream movement of all fish species and also because of water quality issues (principally phosphate) reflected in altered phytobenthos.<br /> <br /> The outcomes of the project are the following: enhanced habitat connectivity throughout both catchments allowing all fish species, migratory and non-migratory, maximum scope to spawn and feed; improved knowledge of fish populations and behaviours through baseline and post-implementation monitoring and evaluation; progress toward/achievement of Good Ecological Status and focus on any residual water quality issues required to achieve good status; establishment of partnership working and joint delivery to be ex-tended under the auspices of the Wear Catchment Management Plan.<br /> <br /> Further funding from the Catchment Restoration Fund as well as Durham County Council and Durham University allowed for the provision of a rock pool fish easement at a road culvert on at Cornsay Colliery located on Hedleyhope Burn (a tributary of the River Deerness), completed in September 2012. Hedleyhope Burn is 9.2km in length. The road culvert has been cutting of fish access to 5km of good quality habitat, as under most flow conditions the culvert becomes impassable. This 30m corrugated steel pipe has rapid and shallow uniform flows when water levels are low, and concentrated high velocity flows at high water levels. An extensive erosion pool at the downstream exit to the culvert exhibits the force of water leaving the culvert. A wide concrete step 15 to 20 cm above the surface of the water also obstructs fish passage into the culvert. The solution was to replace the existing scour pool with a series of rock pools to provide a variety of flows for fish, as well as drowning out the concrete step by increasing water levels back into the culvert and creating a slower and deeper flow, improving fish passage. Flood risk was not increased as the site is in a deep depression with no buildings close by. The site is owned by Durham County who also contributed half of the cost. The Wear Rivers Trust helped with the design of the rock pool easement. Due to the location in a high rainfall upland area, 2-3 tonne rocks were used to form a continuous line of bank protection to protect the site a high flow levels.

Under CRF a Durham University PhD student, with WRT and volunteer support, will survey below and above each obstruction both before and after restoration activities to measure impacts on those animal groups. Changes in invertebrate communities are not expected as a direct result of the restoration activities but they can inform on the wider food web for fish feeding opportunities, and provide biotic indices of water quality, giving wider insight into local environmental quality. Waste water management is significant across the Lower Wear system, including these two catchments.

Land use is largely agricultural, with woodland cover and several reclaimed open cast and landfill sites. A significant part of the catchment fails the Water Framework Directive for fish, due to the cumulative effects of barriers to the upstream and downstream movement of all fish species and also because of water quality issues (principally phosphate) reflected in altered phytobenthos.<br /> <br /> The outcomes of the project are the following: enhanced habitat connectivity throughout both catchments allowing all fish species, migratory and non-migratory, maximum scope to spawn and feed; improved knowledge of fish populations and behaviours through baseline and post-implementation monitoring and evaluation; progress toward/achievement of Good Ecological Status and focus on any residual water quality issues required to achieve good status; establishment of partnership working and joint delivery to be ex-tended under the auspices of the Wear Catchment Management Plan.<br /> <br /> Further funding from the Catchment Restoration Fund as well as Durham County Council and Durham University allowed for the provision of a rock pool fish easement at a road culvert on at Cornsay Colliery located on Hedleyhope Burn (a tributary of the River Deerness), completed in September 2012. Hedleyhope Burn is 9.2km in length. The road culvert has been cutting of fish access to 5km of good quality habitat, as under most flow conditions the culvert becomes impassable. This 30m corrugated steel pipe has rapid and shallow uniform flows when water levels are low, and concentrated high velocity flows at high water levels. An extensive erosion pool at the downstream exit to the culvert exhibits the force of water leaving the culvert. A wide concrete step 15 to 20 cm above the surface of the water also obstructs fish passage into the culvert. The solution was to replace the existing scour pool with a series of rock pools to provide a variety of flows for fish, as well as drowning out the concrete step by increasing water levels back into the culvert and creating a slower and deeper flow, improving fish passage. Flood risk was not increased as the site is in a deep depression with no buildings close by. The site is owned by Durham County who also contributed half of the cost. The Wear Rivers Trust helped with the design of the rock pool easement. Due to the location in a high rainfall upland area, 2-3 tonne rocks were used to form a continuous line of bank protection to protect the site a high flow levels. Larger gravels were also used, and willow spiling is due to be installed at a later stage.<br /> |Monitoring surveys and results=The Wear Rivers Trust operates fish and invertebrate surveys to assess fish populations and water health in both catchments. Under CRF a Durham University PhD student, with WRT and volunteer support, will survey below and above each obstruction both before and after restoration activities to measure impacts on those animal groups.

There were several strategies in existence for the Idle and many partners interested in the catchment. We were also finalising the Isle of Axholme Flood Risk Management Strategy. With so many organisations keen to be involved in the enhancement of the river, the project established an overarching Management Group, which brought together partners to ensure efficient and complementary working towards a shared vision. Such a &quot;joined-up&quot; approach offered better opportunities for innovation and access to funding than working in isolation.<br /> <br /> A connection with the River Idle has been installed SK6956684463 to allow fish and eels to escape from the River Idle in high flows. The reed fringed pond connected to the river will also provide spawning opportunities. As the river level rises a valve will close to prevent water washing away habitat in the pond. Fish will be able to return to the river as its level falls.<br /> <br /> The River Idle has been heavily modified over the years and typically lacks in-channel habitat. An existing berm was lowered and planted with common reed to create habitat for nesting birds and invertebrates. In order to enhance the newly created berm for fish a backwater was created to allow fish to move from the main channel into the backwater during high flows. <br /> <br /> Following its establishment, the River Idle Management Partnership has been well attended. The Management Partnership comprises stakeholders with a diverse range of agendas and priorities, reflecting the national tensions and conflicts between water quality, flood risk management and the environment. This initially disparate group has worked through some significant areas of potential conflict to arrive at a good degree of mutual understanding. It is significant that several local farmers and landowners have become regular attendees. Several members of the partnership also attended the Rural Stakeholders Workshop for the wider Idle Catchment event that NWT organised through their catchment hosting role. It was reported back to us that it had been very useful to make the connections with upstream activities in the Maun and Meden and how this affects them on the Idle, and so how we need to think in a catchment-scale manner. <br /> <br /> The partnership agreed that before any maintenance work is undertaken along the River Idle; a survey was required to ascertain how much silt is present and location of priority areas. At the October 2014 meeting it was confirmed that funding has been made available to undertake the silt assessment. While it was widely agreed by the Catchment Partnership that siltation was an issue, for flood defence and environmental reasons including SSSI condition, the extent of the silt burden was then unknown. Subsequent work by the Isle of Axholme and North Nottinghamshire Water Level Management Board using Environment Agency data from 1994 &amp; 2001 estimated the volume of silt at c146,000m3, the cost of de-silting this volume was estimated at £4,000,000.

There were several strategies in existence for the Idle and many partners interested in the catchment. We were also finalising the Isle of Axholme Flood Risk Management Strategy. With so many organisations keen to be involved in the enhancement of the river, the project established an overarching Management Group, which brought together partners to ensure efficient and complementary working towards a shared vision. Such a &quot;joined-up&quot; approach offered better opportunities for innovation and access to funding than working in isolation.<br /> <br /> A connection with the River Idle has been installed SK6956684463 to allow fish and eels to escape from the River Idle in high flows. The reed fringed pond connected to the river will also provide spawning opportunities. As the river level rises a valve will close to prevent water washing away habitat in the pond. Fish will be able to return to the river as its level falls.<br /> <br /> The River Idle has been heavily modified over the years and typically lacks in-channel habitat. An existing berm was lowered and planted with common reed to create habitat for nesting birds and invertebrates. In order to enhance the newly created berm for fish a backwater was created to allow fish to move from the main channel into the backwater during high flows. <br /> <br /> Following its establishment, the River Idle Management Partnership has been well attended. The Management Partnership comprises stakeholders with a diverse range of agendas and priorities, reflecting the national tensions and conflicts between water quality, flood risk management and the environment. This initially disparate group has worked through some significant areas of potential conflict to arrive at a good degree of mutual understanding. It is significant that several local farmers and landowners have become regular attendees. Several members of the partnership also attended the Rural Stakeholders Workshop for the wider Idle Catchment event that NWT organised through their catchment hosting role. It was reported back to us that it had been very useful to make the connections with upstream activities in the Maun and Meden and how this affects them on the Idle, and so how we need to think in a catchment-scale manner. <br /> <br /> The partnership agreed that before any maintenance work is undertaken along the River Idle; a survey was required to ascertain how much silt is present and location of priority areas. At the October 2014 meeting it was confirmed that funding has been made available to undertake the silt assessment. While it was widely agreed by the Catchment Partnership that siltation was an issue, for flood defence and environmental reasons including SSSI condition, the extent of the silt burden was then unknown. Subsequent work by the Isle of Axholme and North Nottinghamshire Water Level Management Board using Environment Agency data from 1994 &amp; 2001 estimated the volume of silt at c146,000m3, the cost of de-silting this volume was estimated at £4,000,000. The volume and extent of this task is beyond the ability of single landowners to undertake.<br /> <br /> The catchment partnership will continue to take forward actions to improve the river and realise multiple benefits.<br /> |Monitoring surveys and results=Working with landowners to create species-rich grassland buffer strips to reduce diffuse agricultural pollution from adjacent arable land through absorption of agricultural run-off. We installed hinged large woody debris to improve channel conditions for benefits for fish spawning and aerate flows.
