Sea Horse Ranch Dike, located in Grays Harbor, Washington, is a private structure designed to protect the surrounding area from flooding.
Completed in 1961, this Earth-type dam stands at a height of 15 feet and stretches 165 feet in length. With a storage capacity of 75 acre-feet, the dike plays a crucial role in managing water resources along Tr-Gillis Slough, with a drainage area of 0.3 square miles.
Managed by the Washington Department of Ecology, Sea Horse Ranch Dike is regulated, inspected, and enforced by the state to ensure its structural integrity and safety. Despite its low hazard potential, the dam has not been rated for its condition assessment, indicating a need for further evaluation. With a primary purpose categorized as "Other," the dike serves as a vital component in the region's water resource infrastructure, showcasing the importance of private entities in managing water-related challenges.
Located in Congressional District 06, Washington, Sea Horse Ranch Dike stands as a testament to the collaborative efforts between private owners and state agencies in safeguarding communities against the impacts of climate change. While not under the jurisdiction of federal agencies, the dike's role in flood protection highlights the need for continuous monitoring and maintenance to ensure its effectiveness in mitigating potential risks. As water resource enthusiasts and climate advocates, understanding the significance of structures like Sea Horse Ranch Dike is crucial in promoting sustainable water management practices for the future.
