Clevedon Marine Lake will soon be back to normal following a E.coli breakout as MARLENS volunteers prepare to drain the lake.

Swimmers have been warned to take extra care when swimming for more than two weeks after traces of the bacteria, which can cause vomiting and diarrhoea, were found for the second time in two months.

The Marine Lake Enthusiasts (MARLENS) tested the water levels on August 17 where they discovered it was ‘poor’.

The last over-topping tide on August 15 refilled the lake with poorer quality water from the Severn estuary, due to heavy rain washing inland pollutants down-river which led to the lake’s lengthy closure.

A similar situation took place in July when E.coli was first found in the water but was back to normal after a few days.

But now the volunteers who run the lake are taking action to get the lake back up to health standards. The lake will be drained down and refreshed on Saturday.

The penstocks will then be opened around 8.30am, as soon as the tide allows, and the lake should refill around 6.40pm.

There will be 12 more tides which will fill the lake across the six days.

A MARLENS’ spokesman said: “As well as freshening up the water, the drain down provides a great opportunity to clean out the splash pools and lake bottom.

“There is a lot of work to be done so we’re inviting the community to get stuck in.

“Any volunteers wishing to help with this Saturday’s clean-up would be much appreciated – the more the merrier.

“But it does not stop there. There is likely to be a significant amount of debris and seaweed left behind after the over-topping tides between September 8-14, so MARLENS is also calling on volunteers to help clear it up on September 15 at 10am.”

MARLENS restored Clevedon Marine Lake in 2015 and dedicated volunteers help to maintain the site to keep it open for community use.
