Eau Claire Dam
The concrete gravity dam was dedicated on August 12, 1937 as the result of the largest Depression-era Works Progress Administration project in the entire state. Also known as the Eau Claire River 2WP224 Dam or the Augusta Dam (it stands about six miles north of Augusta, Wisconsin), the dam was developed on the site of the previous "Main River Dam" as a 24-foot high, 251-foot long structure impounding the Eau Claire River.
The reservoir it creates, Eau Claire Lake, has a normal surface area of 1.7 square miles, with a maximum capacity of 17,000 acre-feet and normal storage of 7200 acre-feet. Recreation includes fishing (for musky and walleyed pike), boating and swimming. The county operates two units of its Lake Eau Claire County Park north and south of the lake itself.
The dam is one of several in the Eau Claire – Chippewa Falls metropolitan area on the Eau Claire and Chippewa Rivers. As of 2010 the possibility of developing hydroelectric power at this dam was being investigated.
