Clydach reservoir draining environmental vandalism, says petition

“Not only does it help improve the physical health of local people… it has a hugely positive benefit on our mental health and wellbeing,” it said.

The petition said the reservoir could be used to “manage flood risk by storing and slowly releasing flood water, lowering the peak flows of the Clydach and Taff rivers”.

It went on to say that as well as being an important wildlife habitat, its water was also used to tackle forest fires during the summer.

Welsh Water said previously that it has a “lot of work to do in developing the plans, which we will share with the local community once they are complete”.

“We would also like to reassure the local community that protecting the wildlife on site is a priority for us.

“We engaged with Natural Resources Wales before we commenced the draining of the reservoir, and we will continue to engage with them as we develop the plans for the work.”
