General Watershed Information

What is a Watershed?


A watershed is any area of land that drains to a common point. It can also be defined as the area of land that catches rain and snow and drains into a marsh, stream, river, lake, or groundwater.

In the Tri-County region of Clinton, Eaton and Ingham Counties, there are several watershed groups that are working hard to protect, improve, conserve, and promote the water resources of mid-Michigan and ultimately the Great Lakes.

Grand River Watershed


On a large scale, the Greater Lansing area falls within the Grand River Watershed, which eventually drains into Lake Michigan. The urbanized area around the City of Lansing lies within a portion of the Upper Grand River Watershed, which has been broken into three small watershed areas. They are identified as the Grand River Watershed, the Looking Glass River Watershed and the Red Cedar River Watershed and are depicted in the map below.
