Water quality excellent despite crowds

It’s been a busy couple of weeks at Clevedon Marine Lake. From dawn to dusk, people have been arriving in their droves to swim, paddleboard and enjoy being by the water.

Over the last few years, crowds plus warm water temperatures have led to a drop in water quality. But, not this year. We have been taking regular samples to be tested at a local lab and the water quality has remained ‘excellent’.

Safe and fun

Keeping the lake safe and clean is our priority. Every morning, our volunteers clean up litter from the day before. But this hasn’t been easy. Not only have people been leaving lots of litter, but also broken glass and even dog poo. This is dangerous for people with bare feet, children playing and risks affecting the water quality.

You can help

To help us keep our lake clean and safe for everyone, please:

  • take all litter home with you or use the big wheelie bins on the upper promenade
  • don’t bring your dog to the lake
  • avoid single-use plastics where you can
  • don’t bring glass bottles
  • buy wooden crabbing lines
  • keep barbecues off the ground (they damage the concrete when hot)

You can also donate to support our charity’s work or volunteer to help the morning clear-up.

If you’re spot anything that’s broken or damaged, please get in touch. If you’re concerned about anti-social behaviour at the lake you can report it to Avon and Somerset Police here.

Get stuck in!

Every year, we drain the lake to remove the silt build-up. But this is also our chance to clean seaweed and algae off the steps, fix broken or worn fittings, add new features and facilities… and search through the mud for lost property!

All this work is done by a team of volunteers. And you can help too. On Saturday 20th March, we will meet by the lock-up on the upper-promenade near the coastguard’s hut from 9 am. Or, you can turn up at any point and ask a volunteer in a turquoise tabard what you can do.

  • Open penstock, 9-10 am and put out barriers.
  • Close penstock, 7 pm.

Saturday 20th March, 9 am to 6 pm: 

  • Open lower lake penstock to drain out residual water, then close it
  • Search lake bed for lost property and bring anything of value to the shuttered
    shelter to be recorded
  • Remove debris from lake bed. Check the edges carefully for broken glass
  • Scrub weed from steps and handrails, using wire brushes
  • Tighten bolts
  • Pressure wash splash pool and slipway

Note: High tide (6 am, 6.15 pm) may start to refill the lake depending on the weather.

  • Put up flags on all the remaining flagpoles
  • Remove barriers

The lake will refill from the overtopping tide at 7.30 am on Sunday 28th March.

Voluntary work is allowed under government guidance. Please make sure that you keep socially distanced, bring your hand sanitiser and your own gardening or rubber gloves. Please don’t come if you or anyone in your household has symptoms of coronavirus, or if you have been told to self-isolate.

All ages and abilities are welcome. Volunteering work is done at your own risk.

Can’t help this time?

Please consider donating to Marlens, the charity that looks after the lake.

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
