Summary
8, also known as Lampbright Reservoir No. 8, is a privately owned structure located in Grant, New Mexico. Completed in 1974, this earth dam stands at a height of 45 feet with a hydraulic height of 40 feet and a structural height of 50 feet. The dam's primary purpose is listed as "Other," with key features including a spillway width of 50 feet and a drainage area of 0.4 square miles. The reservoir has a storage capacity of 44.3 acre-feet, with a normal storage level of 30 acre-feet.
Managed by the Office of the State Engineer in New Mexico, Chino Mines Dam No. 8 has a low hazard potential and is currently in satisfactory condition, according to the latest inspection conducted in June 2020. The dam has a moderate risk assessment rating of 3, indicating a need for ongoing monitoring and management measures to ensure its safety and stability. With a history of state regulation, inspection, and enforcement, this dam plays a vital role in water resource management and climate resilience efforts in the region.
Situated on the Lampbright Draw river, Chino Mines Dam No. 8 serves as a key infrastructure for water storage and flood control in the area. With a surface area of 2 acres and a maximum discharge capacity of 1450 cubic feet per second, this dam plays a crucial role in managing water resources and mitigating potential risks associated with extreme weather events. As a significant component of the state's water infrastructure, Chino Mines Dam No. 8 underscores the importance of proactive monitoring and maintenance to ensure the safety and reliability of water resources in New Mexico.

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.
