Thunderbird Creek. As a private-owned structure regulated by the Washington Department of Ecology, the dam stands at a hydraulic height of 14.5 feet, with a normal storage capacity of 12.6 acre-feet and a maximum storage of 20 acre-feet. The dam's earth-type structure with stone core and soil foundation spans 1.8 acres, serving a drainage area of 0.16 square miles.
With a high hazard potential and fair condition assessment as of August 2018, Cedar Heights Dam undergoes inspections every five years to ensure its structural integrity and operational efficiency. The emergency action plan (EAP) for the dam was last revised in September 2019, reflecting the ongoing commitment to preparedness for potential risks and emergencies. Despite its private ownership, the dam plays a crucial role in mitigating flood risks in the region, highlighting the importance of maintaining and managing water resources to adapt to changing climate patterns and protect communities downstream.
