Fawn River is located in the northwestern portion of the county. It is the second largest watershed in the county, accounting for 103 square miles of the county’s drainage.
The main channel of Crooked Creek begins at the outlet of Jimmerson Lake and flows west northwest, passing north of Orland and into LaGrange County. Fawn River makes up part of the headwaters which flow into the St. Joe River, near Elkhart, Indiana, eventually out letting into Lake Michigan.
The Fawn River watershed contains the majority of lakes in the county including: Lake George, Snow Lake, Lake James, Jimmerson Lake, Crooked Lake, and Lake Gage. The water quality of these lakes and the others in the watershed are important not only to the residents of Steuben County, but downstream as well.
