About This Place
Eaton Rapids is a city in Eaton County in the U.S. state of Michigan. The population was 5,214 at the 2010 census.
The city is located in the south of Eaton Rapids Township, on the boundary with Hamlin Township, though it is politically independent of both townships. Its nickname is the Island City since downtown is an island, with a public park, in the Grand River.
The area constituting Eaton Rapids was first settled by pioneers around the year 1835, mainly for the timber and water power in the area. The following year, a sawmill was constructed near Spring Brook in Spicerville that would provide the lumber used to start Eaton Rapids. In 1837, the Old Red Mill was constructed by the mill company and used the power from the stream to grind corn. The mill company later used wood from Spicerville to construct their own sawmill along the Grand River, as well as a wool carding mill.
