When temperatures climb and the summer sun beats down, conditions are ripe for Minnesota lakes to produce algae blooms, some of which are harmful to pets and humans. Algae blooms are common throughout the summer, with different species appearing from time to time. While many types of algae are not harmful, when in doubt, best keep out! The Minnesota Pollution Control Agency (MPCA) maintains a webpage with helpful information about blue-green algae and harmful algae blooms.
If you believe you or your pets are experiencing adverse health effects due to contact with, or ingestion of, lake water/algae, seek medical attention immediately. Potential harmful algae blooms should be reported to the MPCA at (651) 757-2419.
