Summary
This earth dam, completed in 1965, serves multiple purposes including irrigation and other water resource management functions. With a height of 12 feet and a length of 1630 feet, this dam has a storage capacity of 70 acre-feet and covers a surface area of 7 acres.
Located on the Humboldt River, the Elko South Waste Water Pond Dam is regulated by the Nevada Division of Water Resources and undergoes regular inspections to ensure its safety and functionality. With a low hazard potential and fair condition assessment, this dam plays a crucial role in water management in the region. Despite its high risk assessment rating, the dam is equipped with controlled outlet gates and sluice gates for water release, minimizing potential risks associated with high water levels.
Although the Elko South Waste Water Pond Dam has a low hazard potential, its risk management measures and emergency preparedness are continually evaluated to mitigate any potential threats. With its strategic location and role in water resource management, this dam remains a key infrastructure for the local community and contributes to the overall sustainability of water resources in the 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.
