College Hill Reservoir, located in Hoquiam, Washington, is a historic water supply reservoir completed in 1899. Managed by the Washington Department of Ecology, this reservoir serves as a crucial offstream source from the Little Hoquiam River for the local community. With a storage capacity of 25 acre-feet and a surface area of 1.46 acres, the reservoir plays a vital role in ensuring water availability for the region.

Despite its age, College Hill Reservoir is facing challenges in terms of its condition assessment, as it has been rated as poor with a high hazard potential. The last inspection in 2018 highlighted the need for improvement and regular maintenance to ensure the safety and reliability of the structure. Additionally, the reservoir lacks certain key features such as a spillway and outlet gates, which are essential for managing water levels and ensuring proper functioning.

As a significant water resource in Grays Harbor County, College Hill Reservoir is closely monitored and regulated by state authorities. Its strategic location and historical importance make it a valuable asset for water supply purposes in the region. However, efforts must be made to address the current condition assessment and implement necessary risk management measures to safeguard the reservoir's long-term functionality and resilience in the face of changing climate conditions.
