The heat is now creating some great growing conditions in Minnesota lakes for blue-green algae.
The Minnesota Pollution Control Agency says the toxic algae has been spotted in southern and western Minnesota, and now it's spreading into the metro. The algae can be deadly in pets and can make people very sick.
The algae looks like spilled oil paint on the surface of the water. It can be blue, green or gray as it decomposes.
The Minnesota Pollution Control Agency says when it doubt stay out of the water.
