What is a watershed?
A watershed is the area of land where all of the water that is under it or drains off of it goes (sheds) into the same place. In the area covered by the Gull Lake Watershed, all of the ground and surface water ultimately drains into Gull Lake.
The Gull Lake Watershed spans four townships in two Southwest Michigan counties. Anything that affects to ground or surface water in our watershed potentially affects water quality in Gull Lake and beyond in the Kalamazoo River and Lake Michigan.
