Completed in 1949, this earth dam is 24 feet in hydraulic and structural height, with a length of 300 feet and a storage capacity of 78 acre-feet. The primary purpose of the dam is to serve as a fish and wildlife pond, supporting recreation activities for enthusiasts in the area.
With a drainage area of 0.53 square miles and a maximum discharge of 308 cubic feet per second, Swano Lake Dam plays a crucial role in managing water resources in the region. However, recent inspections have shown that the dam is in poor condition, with a high hazard potential. The last assessment conducted in 2019 highlighted the need for improvements to ensure the safety and integrity of the structure.
As water resource and climate enthusiasts monitor developments around Swano Lake Dam, attention is being drawn to the need for maintenance and potential risk management measures. With the Washington Department of Ecology overseeing regulation, inspection, and enforcement, stakeholders are keeping a close eye on the dam's condition to safeguard the surrounding environment and communities from any potential hazards.
