Figure 1: The Ottawa-Stony (North) watershed begins in Washtenaw County and flows through Wayne and Monroe counties before emptying into the Western Lake Erie Basin.
The Ottawa-Stony North (OSN) is the northern half of the Ottawa-Stony Watershed. The Ottawa-Stony is actually cut in half thanks to the Raisin River. While its southern boundaries contain most of Monroe County and extends into Ohio, its northern border includes Monroe, Washtenaw, and Wayne County (Figure 1).
In 2020, the WCCD applied for a grant through Michigan’s Department of Environment, Great Lakes and Energy (EGLE) Non-point Source Program to develop the first state-approved watershed management plan for the OSN. In 2021, WCCD was awarded grant to undertake the project in partnership with the Monroe Conservation District and local governments.
In November of 2024, the Ottawa-Stony North Watershed Management Plan was approved by Michigan’s Environment, Great Lakes, and Energy (EGLE) and the Environmental Protection Agency (EPA). This plan has been four years in the making, and we are happy to share it with all of you!
