Some cyanobacteria produce toxins. They can multiply in lakes and ponds as well as rivers.
Before swimming or canoeing, read the site notices: monitoring results and restrictions can guide your decision.
Avoid water activities in areas where cyanobacteria develop and accumulate. Looking at the water does not replace local instructions.
Keep young children from playing with accumulations on banks, stones or the surface of the water.
Keep dogs on a lead so they cannot access affected waters. Severe animal poisonings have been reported.
If exposure is followed by redness, itching or digestive symptoms, shower and consult a doctor, specifying the location.
