Population and
Acreage in the
Indiana Portion of the St. Joseph River Basin
A river basin is comprised of a number of sub-watersheds. The boundaries of watersheds are determined by the slope of the land surface, and the general fall ("gradient") of the drainage-way, whether it be a river, creek or stream, or drainage ditch. Glacial activity in the region influenced where the boundaries lie and how the natural drainage-ways will flow.
The Indiana portion of the St. Joseph River Basin consists of all or portions of seven counties: DeKalb, Elkhart, Kosciusko, LaGrange, Noble, St. Joseph and Steuben.
The chart below pictures the percentage of the River Basin contributed by each county.
