This is a nightmare. A few years back there was such a bloom in lake Erie I check with the people at Berkey Filters and they said at that time even their filter was not able to filter out such toxin
Cyanobacteria
Harmful algal blooms in freshwater lakes and rivers, or at estuaries, where rivers flow into the ocean, are caused by cyanobacteria, also known as “blue-green algae”.[7] They can produce hazardous toxins, such as microcystins,[8] a neurotoxin which destroys nerve tissue of mammals.[9] In high enough concentrations, water treatment plants may be unable to remove the toxin and will advise residents to avoid drinking tap water, as happened in Toledo, Ohio in August 2014.[10]
They also cause harm by blocking the sunlight or by using up the oxygen needed by fish or plant life, which can lead to fish die-offs.[5] When such oxygen-depleted water covers a large area for an extended period of time, it can become hypoxic, commonly called a dead zone. These dead zones can be the result of numerous different factors ranging from natural phenomenon to deliberate human interaction. These dead zones are not just limited to large bodies of fresh water as found in the great lakes, but are also prone to bodies of salt water as well.

The Water Dept. is staffed by Republicans from Michigan.
Congratulations. So far, you had the only serious response to the post. It’s a pleasure reading facts, cynicism sucks.
In the Great Lakes that is mainly because of the massive amounts of fertilizer used for corn. Ethanol is the greenie solution to oil and wrecks havoc on waterways.
