Blue-green algae at Paterswoldsemeer and Lettelberterplas

The province of Groningen has today issued a negative swimming advisory for the Lijte beach at Paterswoldsemeer. 

There is a blue-green algae warning for the Lettelberterplas lake.

These updates can be found at zwemwater.nl. This website also keeps track of when warnings are no longer valid.

We made a vlog about the situation in Paterswoldsemeer lake, explaining what blue-green algae is, under what conditions it develops, and why it is so difficult to combat.
