Built in 1957 by the Washington State Fish & Wildlife, this earth dam stands at a hydraulic height of 22.4 feet and serves primarily for recreational purposes. With a storage capacity of 540 acre-feet, the dam covers a surface area of 40 acres and drains a watershed of 48 square miles.
The dam's condition assessment in 2015 rated it as 'fair' with a high hazard potential. While it is state-regulated and subjected to inspections every five years, its emergency action plan was last revised in 1994. Despite its age, Hog Lake Dam continues to provide essential recreational opportunities to the local community. The dam's association with the Seattle District of the US Army Corps of Engineers ensures ongoing monitoring and management to mitigate any potential risks associated with its operation.
Hog Lake Dam's presence not only offers recreational benefits but also highlights the importance of maintaining and managing water resources in an efficient and safe manner. As a significant component of the water infrastructure in Spokane County, this dam plays a crucial role in flood control, water supply management, and wildlife habitat preservation. Its strategic location and design demonstrate the collaborative efforts between state agencies and local communities to ensure the sustainable utilization of natural resources amidst changing climate conditions.
