Project summary
This stretch of river has been subject to a previous project undertaken by the Environment Agency’s predecessors the National Rivers Authority in 1994. This installed 5 small weirs and a toe boarding along a significant length of the river. These structures would now be seen as inappropriate due to the their impact on the morphology of the stream and the requirements of the Thames River Basin Management Plan. The proposal therefore is to removal the silt traps, regrade banks, meander river and remove the check weirs and toe boarding. The Salmons Brook is an urban river running through Enfield, London. The river has large number of issues including water quality due to urban diffused pollution and physical modifications including weirs and hard banks. For this reason the catchment (water body) has been designated as Heavily Modified for urbanisation and flood protection in the Thames River Basin Management Plan with a target of getting the river into Good Ecological Potential by 2027. The section of river from the A10 (TQ3342994308) to Latymer Rd (TQ3389694053), has been identified as section which could be improved relatively significantly through relatively minor interventions. Once the river exists the A10 culvert it passes between 2 allotments with a small footpath running on top of the left bank. At the end of the allotments there’s a footbridge across the river where the left bank opens into a small recreation ground, with the right bank being a housing estate. The informal footpath follows the top of the left bank to Latymer Rd dividing the river from the a junior school.
