St. Cloud Dam
The St. Cloud Dam (also known locally as the Tenth Street Dam) is a dam across the Mississippi River in St. Cloud, Minnesota, in the United States. The dam is 23.3 feet high and features a three foot flip up gate on its top to raise the water level and dragon's teeth at the bottom which are used to disperse energy. The dam also has two, 4.5 MW turbines which generate electricity that is fed into the Xcel Energy power grid.[1]
The dam is used by various hydrology classes at the nearby St. Cloud State University to demonstrate hydrodynamic properties and to show how power is converted into electricity.
During reconstruction of the dam in 1970, a cofferdam was built upstream from the construction site to hold back Mississippi River waters. Due to a structural inadequacy, the cofferdam washed out on October 31, 1970. The energy of the impounded water caused extensive damage to the construction site and downstream areas.[2]
