Significant amounts of bank material were collapsing in to the river, contributing to deterioration of river habitats. Furthermore, there was concern that a well used footpath, adjacent to this section, was at risk of failure in the future if nothing were done to stabilize the bank.<br /> <br /> Works were jointly undertaken by the Environment Agency, Park's Trust and Volunteers to improve public safety and to prevent further deterioration of habitats. <br /> <br /> Willow logs and brash, were collected by the Park's Trust who were undertaking scheduled tree works in the area. These were secured in the channel using fence posts and steel fencing wire (see photos).<br /> |Lessons learn=While the project was successful at stabilizing the bank where it was most at risk (i.e. steep and close to public footpath), the bank poaching caused by dogs has just moved to another location. This should be considered in any similar project that seeks to restore bank that is deteriorating as a result of livestock or recreational activity. Consider where dogs or livestock will next enter the river, and consider whether the river at that point will be sensitive to the pressure. Are there any other unstable banks or important habitats such as spawning gravels that may be impacted? Consider whether fencing or formal drinking bathing points may be required.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=IMG 4816.JPG<br /> |Caption=Large log bundles at base<br /> }}<br /> {{Case study image<br /> |File name=IMG 4821.JPG<br /> |Caption=First row of willow bundles in place<br /> }}<br /> {{Case study image<br /> |File name=IMG 4837.JPG<br /> |Caption=Bundles and wiring<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment}}<br /> {{Site<br /> |Name=Woughton on the Green<br /> |WFD water body code=GB105033037971, <br /> |WFD (national) typology=Low, Medium, Calcareous<br /> |WFD water body name=Ouzel US Caldecote Mill<br /> |Heavily modified water body=Yes<br /> |Protected species present=No<br /> |Invasive species present=Yes<br /> |Average bankfull channel width category=5 - 10 m<br /> |Average bankfull channel depth category=0.5 - 2 m<br /> }}<br /> {{Project background<br /> |Reach length directly affected=30<br /> |Project started=2014/09/09<br /> |Works started=2014/10/09<br /> |Works completed=2014/10/10<br /> |Total cost category=Less than 1 k€<br /> |Investigation and design cost category=Less than 1 k€<br /> |Investigation and design Lead organisation=Environment Agency<br /> |Investigation and design Other contact forename=Rob<br /> |Investigation and design Other contact surname=Clapham<br /> |Stakeholder1 engagement cost category=Less than 1 k€<br /> |Stakeholder engagement Lead organisation=Environment Agency<br /> |Stakeholder engagement Other contact forename=Rob<br /> |Stakeholder engagement Other contact surname=Clapham<br /> |Works1 and supervision cost category=Less than 1 k€<br /> |Works and supervision Lead organisation=Environment Agency<br /> |Works and supervision Other contact forename=Rob<br /> |Works and supervision Other contact surname=Clapham<br /> |Post-project1 management and maintenance cost category=Less than 1 k€<br /> |Post-project management and maintenance Lead organisation=Milton Keynes Park's Trust<br /> |Post-project management and maintenance Other contact forename=Rob<br /> |Post-project management and maintenance Other contact surname=Rieke<br /> }}<br /> {{Motivations<br /> |Hydromorphological quality elements=Substrate conditions, <br /> |Other motivation=Prevent loss of adjacent footpath due to bank collapse<br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Bank stabilisation, <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>

These modifications include impoundment, channelization and tree clearance. These pressures have reduced the resilience of the channel to wider catchment scale pressures from water quality and sediment. <br /> <br /> As a result of these modifications, there is insufficient flow and energy within the channel at many times of the year to move and redistribute sediment within the channel. This has meant that this 'naturally' gravelly river has an overlying layer of fine sediment. This significantly reduces the likelihood of successful spawning by species such as chub, dace and barbel, the latter of which has not been seen on the river for over a decade. <br /> <br /> Such habitats are particularly important to retain on this side channel, as the main river is navigable, heavily impounded, and cannot provide the diversity of habitats found on this channel, all of which are vital to many species at different points in their life cycle. Furthermore, due to navigation on the main channel, options to enhance or restore it are limited.<br /> <br /> The Environment Agency surveyed the side channel and put together a series of enhancement options to address the deterioration, which were then shared and discussed with the local Angling club and landowners. These included: Improving flow over an upstream weir, tree planting, retaining woody material, fencing, gravel jetting, and installing deflectors to keep areas of spawning gravels free from silt and excessive vegetation growth. Both landowners and Angling Club were keen to see these improvements made and offered both their time and money to see them implemented.<br /> <br /> Partnership was vital to success of the project. Very little money was spent on these enhancements with most contributions coming from volunteer time. The angling club have helped with planting of trees (willow whips sourced from local trees), gravel jetting (using agency equipment), and will share the cost of installing fencing with the local landowners Smith &amp; Smith. The Agencies Fisheries and biodiversity team cleared vegetation blocking an upstream weir and installed flow deflectors, again using wood sourced from locally fallen tree that identified for removal as it was blocking a nearby drainage channel.<br /> <br /> While enhancements such as tree planting will take many years until benefits from increased cover, shelter shading, and supply of woody material to the channel are realized. Already, the benefits of the gravel jetting and flow deflectors can be seen. Following the work, the areas of clean gravels have remained, while other areas in the channel (not yet enhanced) have become covered with sediment and clogged with reed growth.<br /> <br /> For the first time in many years, large numbers of fish have been seen congregating around the deflectors in preparation to spawn, including many large chub. Furthermore, we have also seen River Lamprey (a formerly declining species) making use of the clean gravels for spawning.<br /> <br /> This project demonstrates that correctly targeted low-cost measures, undertaken in partnership with committed stakeholders, can make significant improvement to river channel habitat and fisheries value.<br /> <br /> Follow link for YouTube video of spawning gravel enhancements: http://www.youtube.com/watch?v=ubVX4pla10Y&amp;list=UU8XLubOua8P9B1hT0Qb5Tbg<br /> |Monitoring surveys and results=Pre-enhancement fish surveys have been undertaken&lt;br&gt;<br /> <br /> The Environment Agency will continue to monitor this site through electric fishing surveys.<br /> |Lessons learn=Wood for construction of deflectors was sourced locally and work was undertaken by hand.

Despite their size, careful consideration of the prevailing flow and sediment conditions meant they could be placed to achieve optimum benefit.<br /> <br /> In November 2014 some of the wooden posts, used to hold deflectors in place, had to be replaced. The posts were 75 mm diameter and it is thought that the staples and screws used to secure wire to these posts were too large, causing the post to be weakened and split under load. We have since replaced posts with 20 mm re-bar drilled through the deflectors.

Despite their size, careful consideration of the prevailing flow and sediment conditions meant they could be placed to achieve optimum benefit.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Lamprey Spawing.mov<br /> |Caption=River Lamprey spawining on clean gravels<br /> }}<br /> {{Case study image<br /> |File name=Tree Planting.JPG<br /> |Caption=Local angling club planting trees on banktop<br /> }}<br /> {{Case study image<br /> |File name=Side deflector.JPG<br /> |Caption=Example of side deflector<br /> }}<br /> {{Case study image<br /> |File name=Chub by deflector 2.jpg<br /> |Caption=Chub preparing to spawn around 'v' deflector<br /> }}<br /> {{Case study image<br /> |File name=Finished deflector 2.jpg<br /> |Caption=Finished deflector in May 2014<br /> }}<br /> {{Case study image<br /> |File name=Houghton large paired.jpg<br /> |Caption=large paired deflector<br /> }}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment<br /> |Subcatchment=Ouse (Roxton to Earith)<br /> }}<br /> {{Site}}<br /> {{Project background}}<br /> {{Motivations<br /> |Specific mitigation=Land drainage, <br /> |Hydromorphological quality elements=Quantity &amp; dynamics of flow, <br /> }}<br /> {{Measures<br /> |Bank and bed modifications measure=Creation of wooden deflectors, Cleaning of spawning gravels, <br /> |Floodplain / River corridor=Fencing, Tree planting, <br /> }}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{Biological quality element table row<br /> |Element=Fish<br /> |Monitored before=Yes<br /> |Monitored after=Yes<br /> |Qualitative monitoring=No<br /> |Quantitative monitoring=No<br /> |Control site used=No<br /> }}<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>
