More About Water Quality

From a water sample taken on 06/10/23.

Results are deemed 'Excellent' as stated for Coastal and Transitional waters in The Bathing Water Regulations 2013

The water in Clevedon Marine Lake is tested every two weeks* from May to September. It is rated against EU bathing water standards as: excellent, good, sufficient or poor.

Poor water quality usually happens when:

  • There is a heatwave, loads of people use the lake and water temperatures exceed 22 degrees centigrade;

  • The lake is over-topped with water from the Bristol Channel during a pollution warning.

When this happens, you should take extra care to keep yourself well.  We recommend:

  • Using goggles and earplugs when you swim;

  • Using hand sanitiser as soon as you leave the water;

  • Washing your hands before you eat;

  • Showering when you get home;

  • Avoiding swimming when the lake is warm and crowded;

  • Avoiding swimming when the lake has topped over after a storm.

You always use Clevedon Marine Lake at your own risk. Please remember that it is a natural body of water that contains sea life.

*It takes 48 hours to process a water quality test.
