Summary
Situated along the Humboldt River, this earth dam stands at a height of 24 feet and has a hydraulic height of 22 feet, with a storage capacity of 42 acre-feet. Its primary purpose is for flood risk reduction and other uses, with a spillway width of 15 feet to control discharge.
Although the dam's hazard potential is considered low and its condition is assessed as fair, it is inspected every five years to ensure its safety and functionality. The dam has an outlet gate for controlled water release and is designed to withstand moderate risks. Despite its relatively small surface area of 5 acres, the Elko Emergency Effluent Storage Dam plays a crucial role in water resource management in the region, serving as a vital infrastructure for water storage and flood control.
As water resource and climate enthusiasts, it is fascinating to consider the intricate design and engineering behind the Elko Emergency Effluent Storage Dam. Its strategic location, purpose, and regulated maintenance highlight the importance of sustainable water management practices in mitigating flood risks and ensuring water security in the Elko County area.

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.
