King Reservoir (West Dam) dam
King Reservoir (West Dam)
King Reservoir (West Dam) in Idaho is a privately owned water resource managed for irrigation purposes by the USDA NRCS. The dam, completed in 1969, stands at a height of 29.8 feet and has a storage capacity of 300 acre-feet, serving the surrounding area through an unnamed stream and Little McBride Creek. The reservoir covers a surface area of 28 acres and has a drainage area of 1.1 square miles, making it a vital water source for agricultural activities in the region.
Despite being a privately owned structure, King Reservoir is regulated and inspected by the Idaho Department of Water Resources, ensuring its safety and compliance with state regulations. The dam is classified as an earth dam with stone core types and is primarily made of rock and soil foundations. Its condition is assessed as fair, with a significant hazard potential and a high risk rating. The last inspection in June 2018 revealed that the dam meets guidelines and has emergency action plans in place, reflecting a commitment to maintaining safety and preparedness in the face of potential risks.
With its strategic location in Owyhee County, Idaho, King Reservoir plays a crucial role in irrigating agricultural lands and supporting the local economy. The dam's construction by the Natural Resources Conservation Service underscores the importance of sustainable water management practices in the region. As a significant water resource for the community, King Reservoir exemplifies the balance between harnessing natural resources for human use while ensuring the safety and integrity of the infrastructure for future generations.

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 King Reservoir (West Dam)
Where does the data for King Reservoir (West 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 Significant 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.
