Summary
This earth dam, with a height of 8 feet and a hydraulic height of 35 feet, holds a storage capacity of 112 acre-feet. Situated along the Humboldt River, the dam serves to regulate water flow and store water for agricultural use in the region.
Owned and regulated by the Nevada Department of Water Resources, Elko Percolation Pond 2a Dam has a low hazard potential and has not been rated for its condition assessment as of the last inspection in 2017. It features controlled outlet gates and a spillway type of "None", indicating its design for specific water management needs. Despite the high risk assessment due to its location and associated factors, the dam plays a critical role in water resource management in the area.
With its strategic positioning and purposeful design, Elko Percolation Pond 2a Dam stands as a vital component in the water infrastructure of Elko County. As climate change impacts water availability, this dam serves as a key asset for sustainable water management practices in the region, highlighting the importance of maintaining and monitoring such structures for the resilience of water resources in the face of changing environmental conditions.

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.
