Summary
This dam is owned by the local government and falls under the regulatory oversight of the Nevada Department of Water Resources. Completed in 1965, the dam serves multiple purposes including irrigation and other water management functions. With a height of 12 feet and a storage capacity of 150 acre-feet, the dam plays a significant role in managing water resources in the region.
The Elko North Waste Water Ponds Dam is an earth dam primarily constructed with stone core and soil foundation. It spans a length of 1880 feet and covers a surface area of 15 acres, with a drainage area of 0.1 square miles. The dam features two controlled outlets and two slide gates for water discharge. Despite being classified as having a low hazard potential, the dam's condition was assessed as fair during the last inspection in 2017. With a risk assessment rating of 2 (high), there is a need for continued monitoring and risk management measures to ensure the safety and effectiveness of this essential water infrastructure.
In the event of an emergency, the dam's emergency action plan (EAP) status and readiness remain unclear, highlighting the importance of regular updates and adherence to safety guidelines. With the Humboldt River nearby, the Elko North Waste Water Ponds Dam plays a crucial role in water management and irrigation activities in the region. As climate change impacts water resources, maintaining the integrity and functionality of dams like this one is essential for sustainable water management and climate resilience in Elko, Nevada.

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.
