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 red flag if it’s poor and you should not use the lake. This is for your health. It is also so that the sun’s UV rays can kill the bad bacteria in the water.

When the water is poor quality, we will test every few days and wait for either:

• a sufficient, good or excellent water quality result
• the sea to overtop the lake wall and replace the bad water

Please be aware that water quality may be reduced if:

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

You always use Clevedon Marine Lake at your own risk. Please remember that it is a natural body of water and you should take extra care to keep yourself well at all times. 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

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