The planned Cheddar Reservoir 2 project - a massive new reservoir south west of Cheddar - raises several important environmental concerns, particularly because of its proximity to internationally important wetland habitats. The main issue is the potential impact on water levels in the Somerset Levels and Moors, as changes to river flows could affect sensitive ecosystems that support rare birds, aquatic species and protected habitats.
The greatest risk is not the reservoir itself harming birds directly, but alterations to hydrology. If river abstraction reduced water availability to the Levels during sensitive periods, feeding and roosting habitats could deteriorate, affecting wintering wildfowl and breeding waders.
There are also concerns about impacts on the River Axe catchment, fish migration, water quality and biodiversity during both construction and operation.
These risks can be mitigated through careful design and management. Water abstraction should only take place during periods of high river flow, ensuring sufficient water remains to support wildlife and downstream users.
Continuous environmental monitoring can help identify any adverse effects early, allowing operational changes to be made.
Habitat creation and enhancement projects before the project begins - sort of maximum succession planting - can provide biodiversity gains, while fish passes and ecological corridors can protect wildlife movement.
During construction, strict controls on noise, dust, traffic and pollution will be essential to minimise disruption the natural environment, as well as to our local community.
