Dams and reservoirs

There are two major dams on the river. Griggs Dam in Columbus was built in 1904–1908 to impound a water supply for the city. Farther upstream, at Shawnee Hills, the O'Shaughnessy Dam was built in 1922–1925 creating a larger reservoir which was billed at the time as "the finest inland waterway in the United States." Both dams are operated by the city of Columbus. The removal of the Main Street Dam in downtown Columbus, which was built in 1921, began in November 2013. The $35.5 million removal project was initially proposed in the 2010 Strategic Plan for downtown Columbus and was funded by a coalition of public and private entities. Prior to its demolition, the Main Street Dam impounded roughly of the Scioto River, artificially enlarging its width to an average of in downtown Columbus. Once completed, the Scioto Greenways project will reduce the width by nearly half, and expose of land which will be reclaimed as parkland by the city. Riffles and pools will be restored to the river channel, returning it to its natural riparian state. Experts believe the restoration project will result in a healthier river and better habitat for native plant, fish, and mussel species.
