Project summary
The Enler River is a typical arterially drained channel with laminar flow, regular depth and silt deposition. Compensation money from a fish kill prosecution allowed fishery enhancement measures to be planned and implemented. These included deflector groynes to narrow the channel and creat a thalweg, addition of spawning gravels and plums, and the creation of deeper water via a small cross river groyne
Monitoring surveys and results
Pre works fishery assessment and river habitat assessment were carried out, along with photographs. Post works photographs have been taken and this will continue. One year plus fishery assessment and habitat assessment planned for 2015.
Lessons learnt
Opportunisitc work due to compensation monies and public land ownership. The proximity of the Greenway cycle way, and high value market gardening land meant that the reach length had to be limited, and work constrained within the current channel dimensions. Lunkers that had been obtained for inlcusion in the scheme could not be used due to size issues - used elsewhere.
