Three Shells Lagoon, Southend-on-Sea, Essex

Three Shells Lagoon at Southend-on-Sea in Essex is a newly built man made lagoon that opened this summer. The lagoon is the size of a football pitch and is 1.1 metres at its deepest points.

Squiggle was laughing at how I reacted to the cold water initially- but she wore a proper wetsuit, I didn’t!

Despite visiting in the last week of September, it was still warm enough to wriggle into our swimsuits and go for a swim. It was cold, but we soon got used to it! Squiggle enjoyed practising her swimming skills in the sea water, as well as paddling and splashing around in general. I think it’s wonderful to be able to enjoy swimming in a natural environment, whilst not being entirely in the open water with an inexperienced young swimmer. I imagine it would also be great for learning water sports.

One thing I did wonder about was how the lagoon water is kept fresh and hygenic. So I did some research and found the design quite interesting. “Sheets of welded metal inside the rock walls retain the seawater when the tide comes in, whilst rubberised material at the base of the wall will prevent silt and mud from entering and exiting the lagoon. Valves have been installed into the wall so that the lagoon can be emptied and refilled, ensuring a high quality of regularly-replenished bathing water.” (Southend government website) For further information about the lagoon www.southend.gov.uk
