Soldier Annex Dam dam
Soldier Annex Dam
Soldier Annex Dam, located in Coconino, Arizona, is a federally owned structure managed by the USDA Forest Service. Built in 1935, this Earth-type dam stands at a height of 30 feet with a hydraulic height of 27 feet, serving primarily for irrigation purposes. The dam has a storage capacity of 1886 acre-feet and covers a surface area of 106 acres, with a drainage area of 3 square miles along the Jacks Canyon Tributary.
Despite its low hazard potential, Soldier Annex Dam plays a crucial role in providing water resources for irrigation, fire protection, stock watering, and wildlife habitat enhancement in the region. With a moderate risk assessment rating, the dam has been inspected periodically, the last being in August 2017, to ensure its structural integrity and safety. Although not currently rated for condition assessment, the dam continues to support the surrounding ecosystem and community through its water management capabilities.
Soldier Annex Dam's presence in the Two Guns area contributes significantly to water resource management in Arizona. As a key component in the local water infrastructure, the dam serves as a vital resource for both agricultural and ecological purposes. With its historical significance and ongoing maintenance efforts by the Forest Service, the dam stands as a testament to sustainable water resource management in the region, catering to the diverse needs of the community while preserving the natural environment.

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 Soldier Annex Dam
Where does the data for Soldier Annex 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 Low 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.
