Water quality
DAERA rates each bathing season after it ends, using the last four years of samples: the 2027 rating is usually published in autumn 2027.
DAERA advises avoiding bathing during and for up to 48 hours after heavy rainfall. Weekly test results (June to mid-September) are on the DAERA dashboard.
