The Pewaukee dam, located in Waukesha, Wisconsin, serves as a critical water resource for the community. Built in 1842 for recreational purposes, the gravity dam stands at a height of 14 feet and has a storage capacity of 36,900 acre-feet. The dam is situated on the Pewaukee River and covers a drainage area of 27.6 square miles, providing essential flood control measures for the region.
Despite its age, the Pewaukee dam remains in satisfactory condition, with a high hazard potential due to its location and storage capacity. Regular inspections ensure the structural integrity of the dam, with the last assessment conducted in November 2019. The dam's spillway, controlled by a spillway type structure, can handle a maximum discharge of 120 cubic feet per second, reducing the risk of flooding in the area. Overall, the Pewaukee dam plays a crucial role in protecting the community and managing water resources in the region.
