Zoe - Llyn padarnHigh levels of nutrients such as Nitrogen and Phosphorus are known to cause problems with water quality in lakes.

Natural Resources Wales (NRW) have imposed conditions on Dwr Cymru Welsh Water’s (DCWW) permit to discharge sewage effluent to Afon y Bala so far fewer nutrients now enter the lake. DCWW has also improved its network in the area so that there are fewer storm discharges from the sewer system.

NRW are expecting confirmation in autumn 2015 on how they intend to begin long term works to safeguard the lake’s water quality and when it will be finished.

Llyn Padarn has now been designated as Wales’ only freshwater bathing lake and the results of samples taken by Natural Resources Wales there in 2015 have reached the highest “excellent” standard.
