Picacho South Dam dam
Picacho South Dam
Picacho South Dam, also known as Box Canyon Dam, is a local government-owned structure located in Doña Ana, New Mexico. Built in 1954 by the Bureau of Reclamation, this earth dam stands at a height of 28 feet and stretches 1630 feet in length, with a storage capacity of 560 acre-feet along the South Picacho Arroyo. The primary purpose of the dam is flood risk reduction, serving to protect the surrounding area from potential inundation during periods of high discharge.
Despite its vital role in mitigating flood hazards, Picacho South Dam is currently rated as having a high hazard potential and poor condition assessment. The last inspection in December 2019 revealed the dam's structural integrity to be compromised, raising concerns about its ability to effectively manage floodwaters. With its spillway type listed as uncontrolled, there is a pressing need for maintenance and upgrades to ensure the safety and functionality of the dam for the local community.
Given its location and historical significance in flood risk management, Picacho South Dam presents a unique opportunity for water resource and climate enthusiasts to explore the intersection of infrastructure resilience and environmental stewardship. As efforts are made to address the dam's condition and hazard potential, there is a chance to engage in discussions around sustainable water management practices and the importance of investing in critical infrastructure for a changing climate. By highlighting the challenges and opportunities associated with Picacho South Dam, a deeper understanding of the complexities of water resource management and climate adaptation can be achieved.

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 Picacho South Dam
Where does the data for Picacho South 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.
