Swimmers at Clevedon Marine Lake have been asked to stay clear of the water after high levels of e:coli were found. The lake could be closed for a couple of weeks until it is over-topped with fresh water during the busy summer holiday period.
A sample taken on July 30 deemed the water quality poor, which means it is unsafe for swimming in. Red flags have been erected near the entrances to warn people against entering the water.
The red flags will remain in place until the next water quality sample is taken, which is usually every two weeks from April to October rated against EU bathing standards as excellent, good, sufficient or poor. The next guaranteed over-topping spring tide with fresh water is not until the weekend of August 12.
