Aims were to: -increase flow and natural scouring, to encourage self-cleaning of gravels -enhance existing spawning areas up and downstream of Glens Weir -increase parr and barbell habitat -re-instate collapsed banks, re-profile weir pool to increase pool habitats -provide fly refuge area -reduce cattle poaching Dredging in the 1970’s removed thousands of tonnes of gravel to reduce flood risk. This eliminated large areas of spawning habitat for many species of fish. In some places the river has re-naturalised, however routine dredging still takes place downstream as part of the Christchurch flood alleviation scheme. The project aimed to provide new spawning habitat in a previously dredged area. The location was selected based on data gathered by the Environment Agency, The Barbel Society and Ringwood & District Angling Association. Pre-project monitoring work was completed, with post-project monitoring taking place with the help of the RDAA and Barbel Society through catch data, electrofishing and red count data. Around 600 tonnes of Portland stone was used to complete the works; bank stabilisation, old weir structure, flow deflectors and in channel re-profiling. The area was also fenced to prevent cattle poaching, with a gate to allow angler access. The works have lead to increased flows over the spawning area, and the creation of holding features for larger adult fish. Over 100m of river habitat has been restored. In the past the Stour has often been seen as second best compared with neighbouring rivers but this is now changing.
