About this dam

La Luz-Fresnal East Reservoir

Located in the picturesque Fresnal Canyon in New Mexico, the La Luz-Fresnal East Reservoir is a vital water supply structure owned and regulated by the local government. Completed in 1993, this earth dam has a height of 37 feet and a length of 2755 feet, providing a storage capacity of 374 acre-feet. The reservoir serves as a crucial source of water for the city of La Luz, with a normal storage capacity of 309 acre-feet and a surface area of 14 acres.

Despite its importance for water supply, the La Luz-Fresnal East Reservoir poses a high hazard potential due to its poor condition assessment as of January 2018. With a moderate risk rating, it is crucial for authorities to closely monitor and implement risk management measures to ensure the safety and functionality of this key water infrastructure. The presence of an uncontrolled spillway with a width of 8 feet underscores the need for regular inspections and maintenance to mitigate any potential risks associated with high water discharge events.

In light of its significance for the local community and its environmental impact on the surrounding area, the La Luz-Fresnal East Reservoir stands as a symbol of the delicate balance between water resource management and climate resilience. As climate change continues to impact water availability and infrastructure stability, it becomes increasingly important to prioritize the maintenance and regulation of such essential reservoirs to safeguard water security for future generations.

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 La Luz-Fresnal East Reservoir

Where does the data for La Luz-Fresnal East Reservoir 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.
