Lower Grand River Organization of Watersheds (LGROW)
The Lower Grand River Watershed covers the lower portion of the Grand River that drains into Lake Michigan from Ionia County. There are many subwatersheds within the Lower Grand River Watershed (see map). You can find your watershed using the Find My Watershed tool. The Grand River is the longest river in Michigan, spanning 252 miles, and was named O-wash-ta-nong, meaning Far-Away-Water, by Native Americans who lived there prior to settlement.
