Roy Farms Irrigation Pond dam
Roy Farms Irrigation Pond
Roy Farms Irrigation Pond, located in Yakima, Washington, is a privately owned water resource designed for irrigation purposes. This earth dam structure stands at a hydraulic height of 15 feet with a structural height of 14 feet, providing a storage capacity of 15 acre-feet and a surface area of 1.6 acres. Completed in 1989, this pond serves as a crucial water source for agricultural activities in the region.
However, despite its importance, the irrigation pond poses a high hazard potential with a poor condition assessment as of the last inspection in July 2018. The dam's emergency action plan (EAP) is outdated, raising concerns about its readiness to handle potential risks. With the Washington Department of Ecology overseeing state regulation, inspection, and enforcement, there is a need for improved risk management measures to ensure the safety and reliability of this vital water resource.
As climate change continues to impact water availability and quality, the maintenance and monitoring of structures like Roy Farms Irrigation Pond become increasingly crucial. With the hazard potential and condition assessment in mind, it is essential for the owners and regulators to prioritize infrastructure upgrades and emergency preparedness to safeguard against potential disasters and ensure sustainable water management 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 Roy Farms Irrigation Pond
Where does the data for Roy Farms Irrigation Pond 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.
