Anthony Arroyo Dam No. 1 dam
Anthony Arroyo Dam No. 1
Located in Anthony, New Mexico, the Anthony Arroyo Dam No. 1 serves as a crucial flood risk reduction structure along the Anthony Arroyo. Built in 1974 by the USDA NRCS, this earth dam stands at a height of 35 feet with a structural height of 43 feet, offering a maximum storage capacity of 1,012 acre-feet. Despite its importance in mitigating flood risks for the surrounding area, the dam's condition assessment is currently rated as poor, with a high hazard potential, highlighting the need for maintenance and upgrades to ensure its long-term functionality.
Managed by the Office of the State Engineer, this dam is subject to state regulations, permitting, inspections, and enforcement to guarantee its safety and effectiveness. The dam features an uncontrolled spillway with a width of 50 feet and a maximum discharge capacity of 12,900 cubic feet per second. With a drainage area of 5 square miles, the dam plays a crucial role in protecting the local community from potential flooding events. However, its poor condition and high hazard potential underscore the importance of ongoing risk assessment and management measures to safeguard the surrounding area.
As water resource and climate enthusiasts, understanding the critical role that structures like the Anthony Arroyo Dam No. 1 play in flood risk reduction is essential. With its moderate risk rating and high hazard potential, efforts to improve the dam's condition and resilience are paramount to ensuring the safety and security of the residents of Anthony, New Mexico. Collaboration between local government agencies, state regulators, and the dam's owners and designers will be crucial in implementing necessary upgrades and maintenance to enhance the dam's effectiveness in the face of changing climate patterns and increasing flood risks.

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 Anthony Arroyo Dam No. 1
Where does the data for Anthony Arroyo Dam No. 1 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.
