University of Michigan researchers are attributing the decrease to a lack of rain in the area, which has kept fertilizers and other material from washing off of farmland and into the lake.
Don Scavia is the director of U-M's Graham Sustainability Institute. He says the only long-term way to shrink the blooms is to change the farming methods around Lake Erie.
"Increased buffer strips between the farmland and the stream. Changes in the way that they apply fertilizer--when they do it, how they do it. No longer putting manure on frozen ground. These sorts of things are going to be critical."
Scavia says if those changes aren't made, the blooms will continue to grow and cause more problems for the surrounding communities.
