About this dam

Mclead Flood Control Dam

Located in Hatch, New Mexico, the Mclead Flood Control Dam serves as a vital structure for flood risk reduction along the McLeod & Broadhurst Arroyo. Completed in 1951, this earth dam stands at a height of 17.8 feet with a structural height of 25 feet and a length of 6774 feet. With a storage capacity of 720 acre-feet and a spillway width of 100 feet, the dam plays a crucial role in managing water flow and reducing potential hazards in the region.

Despite its significance in flood control, the Mclead Flood Control Dam is currently assessed as being in poor condition, with a high hazard potential. The dam is regulated and inspected by the Office of the State Engineer in New Mexico, ensuring its compliance with state regulations and enforcement. However, with a risk assessment rating of moderate and an inspection frequency of 5 years, there is a pressing need for improved risk management measures and potential rehabilitation to enhance the dam's effectiveness in safeguarding the surrounding area from flood events.

As a focal point for water resource and climate enthusiasts, the Mclead Flood Control Dam stands as a testament to the ongoing efforts to mitigate flood risks and protect communities in Doña Ana County. With its historical significance and critical role in water management, the dam serves as a reminder of the importance of infrastructure resilience in the face of changing climate patterns and increasing water-related challenges.

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 Mclead Flood Control Dam

Where does the data for Mclead Flood Control 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.
