G  In terms of geography, the Grand River rises in Jackson County, and runs about 260 miles north and west, emptying into Lake Michigan near Grand Haven. Although in miles it covers the longest distance, it's watershed area is second to the Saginaw River Watershed. It winds through three major Michigan cities, Jackson, Lansing, and Grand Rapids, along with the smaller communities of Eaton Rapids, Diamondale, Grand Ledge, Portland, Lowell, Ada, Grandville and Spring Lake. Its tributary rivers include the Lookingglass River, Maple River, Mud River, the Flat River, and Thornapple River along with several smaller streams and drains. As for the history, culture, and spirit of the Grand River, much remains to be explored.
