Often the Lake is cleaner than the sea. As it overtops and settles, that is the water for the next two weeks. Pollution in the sea doesn't then come into the Lake.  Fortunately, our causeway (the Lake wall) is low enough to mean that the water overtops in the Lake every two weeks, so it doesn't go stagnant.
When the water settles, it is clear. The colour is the sand colour!
We have greenery growing in the Lake, and fish, eels and crabs. This is good news.
The Environment Agency will test the water during the bathing season (May to September), and we will post the results regularly on our pages here.  We are looking to fundraise to test the water all year.
