Celebrating the heritage and future of Clevedon Marine Lake. Marlens is a local charity determined to ensure that this seafront jewel is kept in service and used for the benefit of the community in Clevedon and North Somerset. We  are working hard to provide a first class leisure facility for people to enjoy, and we ask everyone who enjoys the lake to help us keep it that way. The lake is for people of all ages who enjoy being in or on the water so for health reasons we would ask dogs to keep their owners away from the lower promenade and the children's paddling area.

Lake Drain Down

The lake will be drained on the 10th October (provisional date). It will remain empty until Friday 14th or Saturday 15th of October, when it will naturally refill with the tide. During the drain down our volunteers will, with the help of North Somerset Council contractors,  be clearing silt, removing litter and cleaning steps and slipways. Project contractors Dyer and Butler will also return to site to address snags from the original build, which were deferred to allow us an uninterrupted Summer of fun at the lake!

Lake Water Quality:

Current Water Quality is Excellent. 

Since August 2016 the Environment Agency have been taking water samples from the lake on our behalf. In each sample they test for bacteria that indicate whether there is faecal matter in the water. The bacteria tested for are:          

Escherichia coli or E.Coli (EC)

Intestinal enterococci (IE)

We determine and publish our own water quality classification based on the results the EA provide and the classification they use for designated water bathing sites. Further information on the classifications and what they mean can be found here.
