Trask Lake Dam, located in Mason County, Washington, was completed in 1969 for recreational purposes. The dam, primarily made of earth with a stone core and soil foundation, stands at a hydraulic height of 10 feet and a structural height of 8 feet, impounding Tr-Shumocher Creek to create a surface area of 13.8 acres. The dam has a storage capacity of 140 acre-feet, with a normal storage level of 40 acre-feet, serving as a popular spot for outdoor activities in the area.

Despite its recreational appeal, Trask Lake Dam poses a high hazard potential with a poor condition assessment as of its last inspection in 2018. The dam is regulated by the Washington Department of Ecology and is subject to state permitting, inspection, and enforcement. With a maximum discharge capacity of 95 cubic feet per second, the dam's safety and maintenance are crucial to mitigate any potential risks to downstream communities and the environment.

For water resource and climate enthusiasts, Trask Lake Dam serves as a notable landmark in the region, highlighting the intersection of water management, recreational activities, and dam safety. With its unique design and importance for the local community, the dam's condition and risk assessment are key considerations for ensuring its continued functionality and safety in the face of changing climate conditions and potential hazards.
