Partridge Ranch Dam dam
Partridge Ranch Dam
Partridge Ranch Dam, located in Grant County, Washington, is a privately owned earth dam constructed in 2010 by JUB Engineers for the primary purpose of irrigation. With a hydraulic height of 12 feet and a storage capacity of 24 acre-feet, the dam plays a crucial role in water resource management in the region. However, despite its importance, the dam is classified as having a high hazard potential and poor condition, highlighting the need for regular inspections and potential maintenance.
The Washington Department of Ecology regulates Partridge Ranch Dam, ensuring compliance with state permitting, inspection, and enforcement requirements. The dam is situated offstream, serving as a key component of the local irrigation infrastructure. In the event of an emergency, the dam's Emergency Action Plan (EAP) is crucial for ensuring public safety and mitigating risks associated with potential dam failures. As climate change continues to impact water resources and infrastructure resilience, the maintenance and management of dams like Partridge Ranch Dam become increasingly vital for sustainable water management practices in the region.
Despite its critical role in irrigation and water storage, Partridge Ranch Dam faces challenges related to its hazard potential and condition assessment. With a history of poor maintenance and a high hazard classification, ongoing risk assessment and management measures are essential to ensure the safety and functionality of the dam. As water resource and climate enthusiasts, it is imperative to advocate for sustainable dam management practices and investment in infrastructure resilience to address the growing threats posed by climate change and ensure the long-term viability of water resources in the region.

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 Partridge Ranch Dam
Where does the data for Partridge Ranch Dam 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.
