MADISON, WI (WTAQ) - The Wisconsin Department of Natural Resources is warning people enjoying the state’s lakes to be aware of water which looks like pea soup.

Record high temperatures are causing toxic blue-green algae blooms on many of the state’s recreational waters.

Water which contains green, blue, white, red or brown scum could hurt those who come in contact with it, including pets.

The most common symptoms of blue-green algae poisoning are rash, stomach pain and difficulty breathing.
