Old Quarry Lake Dam, located in Mason City, Iowa, is a local government-owned structure primarily used for recreation purposes. Built in 1977, the earth dam stands at a height of 13 feet and spans 1,012 feet in length, with a storage capacity of 230 acre-feet. The dam, designed by Wallace Holland Kastler, is situated on the Winnebago River and is regulated by the Iowa Department of Natural Resources.
The dam's condition is assessed as fair, with a significant hazard potential and a moderate risk level. It underwent its last inspection in June 2018, with inspections scheduled every five years. The dam features an uncontrolled spillway and is surrounded by a surface area of 24.4 acres, serving as a recreational hub for the community.
