It is always great to see a fish pass develop from an initial design through to the construction phase. Castleford Engineering are currently taking advantage of the great weather and are constructing a fish and eel pass at North Molton Weir on the River Mole, North Devon. The combined fish and eel pass was designed by Fishtek and approved by the Environment Agency earlier this year. The pass, which will consist of a flight of Larinier fish pass and a separate channel containing boss substrate eel tiles, will vastly improve habitat connectivity within the Mole and provide better access to spawning habitat upstream. The configuration of the weir and the leat currently results in a long deprived reach at low flows. The fish pass has been designed to create a roughly equal flow split with the leat to ensure a replenishing flow into the weir pool at all times. Watch this space for pictures of the completed pass!
