Sea Horse Ranch Dike dam
Sea Horse Ranch Dike
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.
Dam data reference
Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Sea Horse Ranch Dike
Where does the data for Sea Horse Ranch Dike come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
