Once the ice is out, we get a few weeks of beautiful blue (albeit cold) water - then comes algae season.
While not all algae - or even all cyanobacteria - is toxic, given the right conditions a lot of it is.
And that means swimmers and water-loving dogs need to know what to look for - and stay away from.
This link to the Minnesota Pollution Control Agency's website has great information on what to look for, possible harmful effects, and to whom you should report an algal bloom. The Minnesota Department of Health also has some helpful information here on the MDH's Harmful Algal Bloom web page.
