Completed in 1935, this rockfill dam stands at a hydraulic height of 30 feet and a structural height of 22 feet, with a capacity to store 14 acre-feet of water. As the primary purpose of the reservoir is water supply, it plays a crucial role in meeting the water needs of the local community.
Despite its importance, the Beacon Hill Reservoir is facing challenges as it has been classified with a high hazard potential and poor condition assessment. With the last inspection conducted in March 2018, the structure requires regular monitoring and maintenance to ensure its safety and functionality. The Washington Department of Ecology oversees the regulation, inspection, and enforcement of the reservoir, highlighting the significance of proper management and risk assessment for this critical water resource.
As climate change continues to impact water resources, the Beacon Hill Reservoir serves as a reminder of the need for sustainable infrastructure and proactive measures to address potential risks. With a focus on water supply and the surrounding environment, it is essential to prioritize the maintenance and improvement of this reservoir to safeguard its long-term resilience and ensure a reliable water source for the community.
