Project summary
The Babingley River rises from chalk springs above the villages of Flitcham and Hillington in North West Norfolk. The Hillington site is located close to the source and includes an impounded online lake known as the ‘Broadwater’. The aim of the project was to revert 420m of lake back to river in order to improve the water quality, remove barriers to fish and eel passage and provide additional spawning habitat for wild brown trout (Salmo trutta). At this site sluice boards were removed resulting in the lowering of the water level. This concentrated the flow and enabled the river to cut a new channel that would be more sustainable in the long term. Improvements in water quality as a result of the work created better habitat and spawning grounds and the removal of the sluice boards allowed free passage for fish to access these areas. However, lowering the water level created a barrier at the upstream weir, which had to be addressed using a pool and traverse fish easement created with rock rolls.
