Summary
This private earth dam, with a height of 74 feet and a hydraulic height of 70 feet, spans a length of 1850 feet and has a storage capacity of 1810 acre-feet. Situated on the North Fork Humboldt River, this structure is state-regulated and inspected by the Nevada Division of Water Resources to ensure its safe operation.
With a low hazard potential and fair condition assessment, this dam is designed to manage a maximum discharge of 150 cubic feet per second through an uncontrolled spillway with a width of 40 feet. The surrounding surface area covers 65 acres, with a drainage area of 2.2 square miles. Despite facing moderate risk, the Jerritt Canyon Evaporation Pond Dam demonstrates a commitment to risk management through regular inspections and a 5-year inspection frequency. For enthusiasts of water resources and climate, this structure exemplifies the importance of infrastructure in mitigating flood risks and managing water resources in arid regions like Nevada.

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.
