Soldiers Meadow dam
Soldiers Meadow
Soldiers Meadow is a Federal-owned irrigation infrastructure located in Sweetwater, Idaho, along Webb Creek. Completed in 1921, this earth dam stands at a height of 69 feet and has a storage capacity of 3,195 acre-feet, serving primarily for irrigation purposes in the area. With a maximum discharge of 7,040 cubic feet per second and a spillway width of 141 feet, the dam plays a crucial role in water management and supply within the region.
Managed by the Bureau of Reclamation, Soldiers Meadow has a high hazard potential and is regulated by the state of Idaho through the Idaho Department of Water Resources. Despite being modified in 1987 for hydraulic and structural improvements, the dam's condition assessment is currently marked as not available. The risk assessment for the infrastructure is rated as moderate (3), highlighting the importance of ongoing monitoring and maintenance to ensure its safety and functionality for the surrounding community.
In the event of an emergency, the dam site has an emergency action plan (EAP) in place, last revised in December 2019. While the risk management measures and inundation maps are not explicitly stated in the data, it is evident that continuous oversight and adherence to regulatory guidelines are essential for the safe operation of Soldiers Meadow. As a vital component of the local water resource infrastructure, the dam serves as a critical asset for irrigation and water supply in Nez Perce County, Idaho.

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 Soldiers Meadow
Where does the data for Soldiers Meadow 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.
