Bonner Dam was built in 1884 (rebuilt in 1886) on the Blackfoot River to hold logs and provide a little energy to the mill. Milltown Dam (aka Clark's Dam), finished in January 1908, was built just passed the confluence of the Blackfoot and Clark Fork rivers by Montana's U.S Senator William A. Clark to supply hydroelectricity to local mills and the city of Missoula. The largest flood ever seen on those rivers occurred six months later, depositing millions of cubic yards of silt laden with heavy metals and arsenic in the Milltown Reservoir from upriver mining sites. As part of a Superfund cleanup site, Bonner Dam was removed in 2005 and Milltown Dam was removed in 2008. The Superfund restoration plan includes a redevelopment effort aimed at economic development and community revitalization.
