Holmes Harbor Reclaimed Water Ponds dam
Holmes Harbor Reclaimed Water Ponds
Holmes Harbor Reclaimed Water Ponds, located in Island, Washington, is a remarkable water resource project that serves as a critical infrastructure for reclaiming water in the region. Owned by a public utility, the ponds are regulated by the Washington Dept of Ecology and have been in operation since 1994. The primary purpose of the ponds is for reclaiming water, with a storage capacity of 50 acre-feet and a surface area of 3.8 acres.
The dams at Holmes Harbor Reclaimed Water Ponds are of Earth type, with a hydraulic height of 50 feet and a structural height of 26 feet. The ponds have a high hazard potential but are currently in satisfactory condition, as assessed in 2014. The facility is subject to regular inspections every 5 years to ensure its safety and effectiveness in reclaiming water for various purposes. The location of the ponds, offstream from any river or stream, highlights their importance in managing water resources in the area.
Overall, Holmes Harbor Reclaimed Water Ponds play a crucial role in water management and conservation efforts in Washington. With its strategic design and operation, the facility contributes to sustainable water use and serves as a model for effective water resource infrastructure. As climate change continues to impact water availability, the ponds provide a valuable resource for reclaiming and reusing water, ensuring a resilient water supply for the community and ecosystem.
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 Holmes Harbor Reclaimed Water Ponds
Where does the data for Holmes Harbor Reclaimed Water Ponds 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 High 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.
