It's a microbial world
Toxic cyanobacteria are spreading in Lake Erie.  The blooms include Microcyctis, which produces neurotoxins and haptotoxins, and filamentous species like Anabaena, Lyngbya, and Aphanazomenon.  These blooms are the result of eutrophication - increased nutrients in the lake from urban runoff and other sources - and pose a risk for human health through the production of toxins, but also for the health of the lake, by causing oxygen depletion when they die and are decomposed by bacteria.  The solution is to reduce nutrient loading, as this article shows, that is not an easy task!
