Why is stormwater bad for the lakes-doesn water help the lakes?
It isn’t the water that falls directly from the sky onto the lakes that is the problem-it is the stormwater that flows over impervious surfaces and ends up flowing into the lakes fast, hot, and dirty. It can pick up pet waste, fertilizers, pesticides, detergents, trash, invasive plant seeds, automotive liquids like motor oil, antifreeze, brake fluid, leaves, grass clippings, etc. All of these things have detrimental effects on the quality of the water in the lakes.
