The lake will be CLOSED on 3rd and 4th June, reopening on 5th from 9am

Clevedon Marine Lake will be closed all day Wednesday and Thursday this week, as well as early Friday morning, to drain and refresh the water following high usage during the half-term heatwave.

The lake will fully refill during Friday’s high spring tide at 7.20am – and will be accessible to the public from 9am on 5th June.  The water quality will be tested on Tuesday 9th June after the series of overtopping tides.

Visitors should check the times and heights of high tides before coming to the lake.  The sea overtops the outer wall of Clevedon Marine Lake at the top of high spring tides of 12.6m or more – refreshing the water in the lake.  The lake becomes part of the Severn Estuary and the seawall is no longer visible.  In addition, the lower promenade can completely disappear underwater during overtops.

Visitors should not enter the lake during overtops, and allow at least one hour either side of these times before entering the lake:

Visitors are asked to use the lake and surrounds respectfully:

  1. Take all rubbish home.
  2. Use the public toilets behind the arcade.
  3. Barbecue on the beach not by the lake.
  4. Respect social distancing on the promenade using the yellow spray lines to stay 2m apart.
  5. Stay off the pontoon (blue island in the middle of the lake) as it is too small to support social distancing.

Stay out of the lake when the tide is over the seawall

A male swimmer was rescued by RNLI helicopter and HM Coastguard this morning after swimming over the seawall into the estuary during the overtopping tide; he was subsequently dragged by the rip and pulled downstream in the ebb, 40 minutes after high tide, which was at 7.43am.  Fortunately, he is reported to be fine.

It is dangerous to access the lake to swim during overtopping tides.  A strong rip is created on the estuary side of the seawall, which can quickly sweep swimmers away from the lake and into the tidal flow.

Clevedon Marine Lake in nestled in the Severn Estuary, which has the third largest tidal range in the world.  This means that the sea at Clevedon has an extremely strong tidal pull.

The sea overtops the outer wall of Clevedon Marine Lake at the top of high spring tides of 12.6m or more – refreshing the water in the lake.  The lake becomes part of the Severn Estuary and the seawall is no longer visible.  In addition, the lower promenade can completely disappear underwater during overtops.

Clevedon Marine Lake overtops approximately every two weeks during spring tides.  Spring tides have the greatest tidal range and occur during the full moon and the new moon phases, twice each lunar month all year long without regard to the season.  In rougher conditions, fresh seawater will spill into the lake before a high tide of 12.6m is reached.

  • Always check tide times and heights when planning your lake visit.  A series of overtops at high tide can last a full week.
  • Know which way the tide is flowing (in or out) when you arrive at the lake.
  • Do NOT enter the lake around high tide when 12.6m or higher tides are expected.

As we approach the peak months for usage of Clevedon Marine Lake – coinciding with the expected easing of lockdown, Marlens, the charity behind the lake, urges people to heed all the advice on site and on the lake website.

During lockdown, Clevedon Marine Lake has remained open for individual exercise, with visitors reminded to maintain a distance of at least 2m from each other.  Users have been requested to access the lake grounds responsibly, in line with Government guidelines and to avoid unnecessary travel.

 

REFRESHING NEWS

Clevedon Marine Lake will be open as normal, full of fresh water from Friday 2nd August, allowing for three overtops to fully refill the lake.  Please note: The lake might not be full on Thursday 1st August.

Refills have become a popular spectacle to watch – as 30 million litres of sea water gushes over the seawall into the lake.  THE LAKE SHOULD REFILL ANY TIME AFTER 6PM ON 31ST JULY.

The penstocks will be opened at around 8am, and volunteers will be cleaning in and around the lake from 10.30am on 31st July.

Clevedon Marine Lake will be closed to the public and fully drained on Wednesday 31st July so that it can refresh with water from the Severn Estuary repeatedly during the next sequence of overtops between 31st July and 5th August.

The water quality will be retested on 7th August, after the overtops.  Updates on the water quality in Clevedon Marine Lake are shared here.

There’s always lots to do at the lake in terms of litter picking, cleaning, muscle work and site management, so if you can spare any time to help out, please contact volunteer@marlens.org.uk
