BART has recently secured funding via the Environment Agency’s Water & Environment Improvement Fund to deliver habitat enhancement projects in two locations along the Cam & Wellow Brooks. The project aims to directly improve two water-bodies that are not meeting Water Framework Directive targets – in particular failing for fish where the classification has declined to poor in the 2016 cycle.

The project scope was developed in partnership with Avon & Tributaries Angling Association, who own the fishing rights of these waters. To date, BART has delivered stakeholder engagement, secured landowner permissions, finalised the project design and secured the required permits to physically deliver the works. Initial clearance and blockage removal will be underway very shortly.

The project will address the following issues:

  • Problematic sedimentation and diffuse pollution – there are multiple locations where livestock poaching is exacerbating bank erosion, causing increased yields of suspended sediments and faecal matter entering the river system. Current practice is likely to be detrimental to the health and recruitment of fish and other aquatic organisms including benthic invertebrates.
  • Poor fish access and supporting habitat – boulder weirs are impounding the flow of the river whilst creating barriers to smaller fish. As a consequence, a stretch of the river has become canalised, characterised by sluggish flows and limited habitat diversity or niches.
  • Limited fish spawning habitat – at present, high-potential spawning habitat is inaccessible to migratory fish due to blockages caused by fallen trees, waste material and collected detritus. Blockages also impound the river, creating unfavourable conditions for fish spawning. If removed there is potential to re-introduce idyllic spawning and juvenile refuge habitat. Livestock poaching is also extensive throughout this reach and will be addressed.
