According to the 1879 book, History of Genesee County, Michigan: With Illustrations and Biographical Sketches, a dam has been located in the vicinity of the current Hamilton Dam since the mid- to late-1800s, and was likely originally associated with the 1848 Hamilton & McGregor mill.
Current Conditions - The current Hamilton Dam was built in 1920 and is a reinforced concrete gravity dam. The dam currently has six steel spillway gates, although three of the gate bays have been permanently closed. Immediately downstream of the dam is the upstream limit of the Flint River Flood Control Project, constructed by the Detroit District, Corps of Engineers in 1979. According to the Hamilton Dam Condition Survey Flint River, Flint Michigan (U.S. Army Corps of Engineers Detroit District, April 2002), the dam is in poor condition and is classified as a high hazard dam. The City of Flint has been under a state mandate since 2008 to lower the water level until repairs can be made to the dam. More information on the current conditions of the dam can also be found in the following August 3 2012 MLive article.
Proposed Reconstruction - The Genesee County Parks and Recreation Commission (County) is coordinating the improvement of the Hamilton Dam. Consumers Energy is working closely with the County, City of Flint, Michigan Department of Natural Resources, Michigan Department of Environmental Quality and others to make sure the East Boulevard former MGP site remediation work and the Hamilton Dam improvements are sequenced to protect human health and the environment.
