Apparently, the blooms even occur when the lake is iced over. I've seen some aerial photos showing them. Cyanobacteria occurs naturally and is found in water and soil, but the prolific and frequent blooms of recent years have been fueled in large part by run-off, fertilizers, antiquated septic systems, etc.
