August 19 2016: cyanobacterias have just been spotted in the lake!

Users of the lake will have gradually noticed that since August 19, the colour “green” is now appearing on the surface.

Given the hot spell that has been forecast over the next few days, it would be surprising that the water improves in the short term.

RBL invites the population to take the usual precautions when faced with these blue-green blooms. All contact with the water should be avoided, especially involving young children. As we said earlier, caution is the word.
