River Taf Water testing May 2026

Laugharne Citizen Science tested the river on the 13th May 2026. The river level was lower than last month, there has been less rainfall in the last month. The only observations was a Kingfisher was seen at the Whitland testing spot and a trout was seen rising to flies below the road bridge in Whitland.

PH levels are still elevated and have been reported to NRW and West Wales River Trust. Phosphate levels were higher at one testing location- probably as potatoes had been sown in the last month in a field adjoining the river on the opposite bank.

Water temperature continues to rise from 9 in Jan to 11.5 in May. The only ammonia recorded was a slight reading at Lower St Clears- which also showed higher phosphate and Nitrate readings.

Other than the high PH readings all seemed OK. We plan to test a few miles upstream of Whitland in June to see what the PH levels etc are there.

No dissolved oxygen readings this month as device unavailable.
