Wynoochee, a gravity dam located in Grays Harbor, Washington, is a key water resource and climate infrastructure owned by the local government. Built in 1972 by the U.S. Army Corps of Engineers, this dam serves multiple important purposes including water supply, flood risk reduction, hydroelectric power generation, recreation, and fish and wildlife habitat enhancement. With a maximum storage capacity of 76,000 acre-feet and a normal storage capacity of 69,405 acre-feet, Wynoochee plays a crucial role in managing water resources in the region.

The dam, standing at a height of 175 feet and stretching 1,700 feet in length, has a controlled spillway with a width of 64 feet. The structure is designed to withstand high hazard potential and is regularly inspected by the Federal Energy Regulatory Commission to ensure its safety and functionality. Despite its age, Wynoochee remains a vital component of the local water supply infrastructure, providing essential services to the surrounding community while also supporting ecological and recreational activities along the Wynoochee River.

As climate change continues to impact water resources and infrastructure across the country, the role of dams like Wynoochee in managing water supply, flood risks, and ecosystem health becomes increasingly critical. With its strategic location and multifaceted benefits, Wynoochee stands as a testament to the importance of sustainable water resource management in the face of a changing climate.
