12. Bulbourne Moor - weir modification

Aims: Improve wildlife corridors; Work together

Water body: River Bulbourne
Project description

Proposal to notch a concrete weir to allow free movement of coarse fish species and reconnect 1.6km of the rivers Bulbourne and Gade.

 A concrete weir beneath a footbridge over the river at Bulbourne Moor which was impounding flow and preventing the movement of fish (in particular coarse fish species) was removed in March 2016 as part of a series of similar projects in the Colne catchment funded by the Catchment Partnership Action Fund. The removal/modification of the weir was first proposed by the Chilterns Chalk Streams Project in 2010, in a report on restoration proposals for the lower R. Bulbourne through Box Moor, commissioned by the Box Moor Trust.  In 2015 the Box Moor Trust was awarded a grant of £5,000 from the Catchment Partnership Action Fund (CPAF) for the work to remove/notch the weir.  A feasibility study recommended notching of the weir over removal. Detailed design work was completed by November 2015. The work was completed by B & W Services in March.  As part of the requirements of the CPAF the success of the project is being monitored by volunteers of the Box Moor Trust (Riverflies) and the Environment Agency (fish).
