About this dam

Mescalero Reservoir Dam

Mescalero Reservoir Dam, located in Torrance County, New Mexico, was completed in 1961 with the primary purpose of flood risk reduction along the Arroyo Ortiz-TR. This earth dam stands at 20 feet in height and spans 553 feet in length, with a storage capacity of 186 acre-feet. Despite its crucial role in mitigating flood hazards, the dam's condition assessment is rated as poor, indicating a high hazard potential that calls for immediate attention.

The dam's location in an unincorporated residence area underscores the importance of its structural integrity for the safety of nearby communities. With a moderate risk rating and a high hazard potential, regular inspections and maintenance are essential to ensure the dam's continued effectiveness in flood risk reduction. The Office of the State Engineer in New Mexico oversees the regulation, permitting, inspection, and enforcement of this dam, highlighting the collaborative effort required to manage water resources in a changing climate and safeguard against potential disasters.

As climate change poses increasing challenges to water resource management, the Mescalero Reservoir Dam serves as a critical infrastructure for flood protection in the region. With a history of poor condition assessment and a high hazard potential, it is crucial for stakeholders to prioritize maintenance and risk management measures to uphold the dam's functionality and safeguard the surrounding communities from potential disasters. Addressing the dam's structural concerns and implementing necessary improvements will be essential in ensuring its continued efficacy in flood risk reduction and resilience against the impacts of a changing climate.

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 Mescalero Reservoir Dam

Where does the data for Mescalero Reservoir 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.
