Which watershed are you in?
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 smaller watershed areas to aid in analysis. For the purpose of this analysis, the local watershed areas are identified as the Grand River Watershed, the Looking Glass River Watershed, and the Red Cedar River Watershed and are depicted in the below map. The GLRC has developed watershed management plans for each of the urbanized subwatersheds shown here.

Because watersheds cross political boundaries, twenty of the communities that fall within these defined local watersheds are a part of a cooperative effort and have formed the Greater Lansing Regional Committee for Stormwater Management (GLRC) to address water quality in our lakes, rivers, streams, and wetlands.
