Built in 1946, this earth dam stands at a hydraulic height of 10 feet and a structural height of 8 feet, with a length of 1000 feet. The dam has a storage capacity of 56 acre-feet and covers a surface area of 7 acres, with a drainage area of 0.2 square miles.
Managed by the Washington Dept of Ecology, the Three Rivers Mill Pond Dam is state regulated, inspected, and enforced to ensure its safety and compliance with regulations. Despite its low hazard potential, the dam's condition assessment is currently not rated, indicating a need for further evaluation. While the dam does not have a spillway or outlet gates, it remains an important structure in the region for water resource management and environmental conservation efforts.
With its strategic location along the Sauk River-Offstream and its contribution to local water storage and management, the Three Rivers Mill Pond Dam underscores the importance of maintaining and monitoring dams for both human and ecological well-being. As water resource and climate enthusiasts, it is essential to recognize the role of such structures in balancing water supply, flood control, and habitat preservation, while also ensuring their safety and compliance with regulatory standards to mitigate potential risks and ensure sustainable water management practices in the region.
