Blue-green algae in lakes Paterswoldsemeer and Lettelberterplas

The province of Groningen issued a negative swimming advisory today for De Lijte Beach on Lake Paterswoldsemeer. 

A blue-green algae warning is in effect for Lettelberterplas.

These updates can be viewed at zwemwater.nl. The site also tracks when warnings are no longer in effect.

We made a vlog about the situation in Lake Paterswoldsemeer, explaining what blue-green algae is, under what conditions it forms, and why it’s so difficult to control.
