Blaming farmers in this instance is complete and total BS. It barely rained for 2.5 months this fall. There wasn't "run off" from farms, it was the solid waste spill in Ann Arbor that caused the bloom around Luna Pier/Monroe. Accident happened like October 3rd (?) nasty bloom was present and got a lot worse from the 10th (Columbus Day) all the way through most of November. We perch fished on the 10th, and it was disgusting. We pier fished (well tried) at LP twice and each time it was nasty as Hell. That wasn't a farmer.....that was AA's sewage.
I'm confused as to how a nuclear power plant could contribute to algal blooms. They pull water from the lake for cooling, and it gets released out the top as steam.
Blame lies on municipalities that do not have sewer separation near tributaries that drain into the lake. Dump a bunch of raw sewage into the Huron River, Maumee River, etc. etc. during July/August/September/October and watch what happens 3-4 days later. The bloom this year looked different because it was a different strain of algae, but at the same time it was also darker, because quite frankly it was literally raw sewage floating on top of the water mixed in with the algae. The air smelled like it does on the downwind side of the crap ponds at Muskegon Wastewater GMU.
Do farming practices such as spreading manure on fields ahead of rain events contribute to algal blooms? Yes, but at a far more reduced rate than say when a city loses control of the raw sewage and millions of gallons of it end up in the river and eventually the lake.
