Summary
7 Dam, also known as Whitewater Reservoir No. Dam, is a privately owned structure located in Grant, New Mexico. Built by Kennecott Copper Company and completed in 1959, this Earth-type dam stands at a height of 107 feet and has a hydraulic height of 102 feet. The dam's primary purpose is flood risk reduction, and it sits along Whitewater Creek in the Santa Rita Mine Pit area.
With a storage capacity of 499 acre-feet, Chino Mines Reservoir No. 7 Dam plays a crucial role in managing water resources in the region. The dam's spillway type is uncontrolled with a width of 50 feet, and it has a low hazard potential with a satisfactory condition assessment. The dam has a moderate risk level and undergoes inspections every 5 years to ensure its structural integrity and safety for the surrounding community.
Overall, Chino Mines Reservoir No. 7 Dam is a significant piece of infrastructure that serves as a vital component in flood risk reduction and water management in the area. With its rock foundation and Earth-type structure, the dam continues to play a crucial role in safeguarding the region against potential flooding events while also providing essential water resources for the community.

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.
