Water quality is excellent

Latest tests of the bathing water quality at Clevedon Marine Lake show that it is now excellent. This means that the sample of water that we tested on June 23rd has very low levels of bacteria, and the lake meets EU standards.

This is great news. It follows a period of low water quality where there were too many bacteria for safe bathing. The change is likely to have happened because UV (ultra-violet) light kills bacteria and because fewer people swam in the lake because of the water quality warning.

Help keep the lake clean

You can help keep the lake clean by following a few simple rules:

  • No dogs in or around the lake – dogs carry germs
  • Take your litter home
  • Avoid overcrowding – if the lake is too busy, come back later

 

 

Water quality is still poor

Our latest tests show that water quality is poor. This means that the water in the marine lake does not meet EU standards for bathing water quality.

The sample of water taken from Clevedon Marine Lake on June 10th showed that the water had higher levels of bacteria than is deemed safe for swimming. The community made a huge effort to empty and clean the lake following the last poor water quality test, but it did not solve the problem as hoped. It is likely that the water from the estuary that refilled the lake was also below standard.

You should not swim in the lake until it has been emptied and refreshed, especially if you have lowered immunity.

If you do swim, please wear goggles and earplugs to protect yourself, and wash your hands before eating.

Red flags around the lake show that swimming is not advised.

Marlens, the charity that looks after the lake will today be deciding on a course of action to refresh the lake once more. Small overtops are due on the 5th to 6th July, although these may not be enough to refill the lake. The next major overtop isn’t until July 21st to 24th.

About water quality

The water quality in the Severn Estuary, which refills the lake, is monitored by the Environment Agency from May to September, with samples taken from Clevedon Beach next to Clevedon Marine Lake. Poor water quality warnings for the estuary are issued online and often coincide with periods of heavy rain, causing run-off from the land. But, the Environment Agency is not currently testing as normal because of the Covid-19 pandemic.

The current tests show the levels of enterococci bacteria remain high compared to previous water samples.
