Releases from Llyn Celyn are controlled by Natural Resources Wales. There are a number of factors taken into consideration for releases including recreation, fisheries, power generation, flood control and water extraction. The National White Water Centre has an excellent relationship with NRW but the National White Water Centre does not have any control over water releases.

Natural Resources Wales advise us of the water releases and, as soon as we have received the release information, we up-date this web-page, our facebook page and the water information line - 01678 520826
