Water quality status

Winter season: no testing

About water quality

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

We will show a green flag if the water is good, a red flag if it’s below standard and you should not use the lake, and an amber flag if:

  • there is a heatwave and water temperatures exceed 22 degrees centigrade
  • the lake is over-topped with water from the Bristol Channel during a pollution warning

If an amber flag is showing, 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.

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