About this dam

Las Cruces Dam

Las Cruces Dam, located in Doña Ana, New Mexico, is a crucial structure designed by the US Army Corps of Engineers for flood risk reduction along the Alameda & Las Cruces Arroyos. Completed in 1975, this earth dam stands at a height of 67 feet with a structural height of 85 feet and a length of 15,570 feet. With a storage capacity of 13,200 acre-feet and a surface area of 550 acres, the dam plays a vital role in protecting the surrounding areas from potential flooding events.

Managed by the local government and regulated by the Office of the State Engineer, Las Cruces Dam is subject to regular inspections to ensure its structural integrity and safety. The dam has a high hazard potential but is currently assessed as being in satisfactory condition. With a maximum discharge capacity of 30,400 cubic feet per second, the dam is equipped with an uncontrolled spillway that is 400 feet wide. Despite its moderate risk level, Las Cruces Dam remains a key component of the region's water resource and climate management infrastructure, safeguarding the community against the impacts of extreme weather events.

Named after the city of Las Cruces, this vital flood risk reduction structure plays a crucial role in mitigating the potential impacts of flooding in the area. With a history of effective operation and maintenance, Las Cruces Dam continues to serve as a reliable defense against the threat of inundation, highlighting the importance of proactive water resource management in the face of changing climate conditions.

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.

FAQ

About Las Cruces Dam

Where does the data for Las Cruces 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.
