Summary
With a storage capacity of 654 acre-feet, this dam stands at a height of 13 feet and serves as a vital water resource for the surrounding area. While the primary purpose of Long Lake is not specified, its construction was completed at an unknown date, reflecting its historical significance in water management.
Despite its undetermined hazard potential and lack of condition assessment data, Long Lake remains an essential component of the region's water infrastructure. The reservoir's emergency action plan status, risk assessment, and management measures are also currently unavailable, highlighting the need for further evaluation and potential updates to ensure the safety and sustainability of this water resource. As climate change continues to impact water availability and quality, the importance of managing and maintaining reservoirs like Long Lake becomes increasingly crucial for ensuring long-term water security in the region.
With its location in the Albuquerque District and under the ownership of the Bureau of Indian Affairs, Long Lake plays a crucial role in water storage and management in New Mexico. As water resource and climate enthusiasts focus on the challenges of sustainable water management, Long Lake serves as a reminder of the ongoing efforts needed to protect and preserve our valuable water resources for future generations.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
