Located in Manson, Washington, the Wapato Lake Dam is a public utility structure that regulates the flow of the Tr-Lake Chelan river. Built in 1912, this earth dam stands at a hydraulic height of 40 feet and serves primarily for recreation purposes, with a normal storage capacity of 2000 acre-feet. The dam's hazard potential is rated as high, although its condition is currently assessed as fair.

With a surface area of 220 acres and a drainage area of 15.3 square miles, Wapato Lake Dam plays a vital role in managing water resources in the region. The dam has state jurisdiction, with regulatory oversight from the Washington Department of Ecology. Despite its age, the dam undergoes regular inspections every 5 years to ensure its structural integrity and safety. In case of emergencies, an Emergency Action Plan (EAP) is in place, with the last revision made in November 2019 to meet safety guidelines. For water resource and climate enthusiasts, Wapato Lake Dam stands as both a historical landmark and a crucial infrastructure piece for sustainable water management in Chelan, Washington.
