Cedar Lake experiencing harmful algae bloom

Contact with affected water can lead to illness.

Cedar Lake is experiencing a harmful algae bloom, according to the Minneapolis Park and Recreation Board.

A blue-green algae bloom is currently present on the lake, the park board announced Friday. According to the Minnesota Pollution Control Agency, blue-green algae is not actually algae but a kind of bacteria. Contact with it can cause sickness including vomiting, diarrhea, rash, eye irritation, cough, sore throat and headache.

Blooms are a vibrant color and might look like spilled paint in the water, according to the park board. 

The park board advises people to avoid swimming in lakes if they cannot see their feet in knee high water. The algae can also be harmful to dogs, so owners should prevent dogs from drinking lake water.

The algae blooms often occur in warm, shallow lakes. According to MPCA, algae blooms are a natural park of lake ecosystems. But they can be made less frequent by preventing nutrients, like fertilizer, from getting into lakes.

Minneapolis beaches, including those at Cedar Lake, will be closed this summer to help prevent the spread of COVID-19.
