Summary
This earth dam, primarily designed for irrigation purposes, stands at a height of 18 feet with a hydraulic height of 35 feet and a structural height of 38 feet. The dam has a storage capacity of 200 acre-feet and covers a surface area of 20 acres, serving the surrounding area with water from the Humboldt River.
Despite its low hazard potential, this dam is regulated and inspected by the Nevada Division of Water Resources, ensuring its safety and compliance with state regulations. The dam boasts a controlled outlet mechanism with two gates, enhancing its functionality for water management. With a drainage area of 0.1 square miles, Elko Percolation Pond 1b Dam plays a vital role in the local water infrastructure, contributing to irrigation and other water-related activities in the region.
Although the dam's condition assessment is currently listed as "Not Rated," its risk assessment is classified as high, signaling the importance of proper risk management measures. As a key component of the water resource system in Elko, this dam underscores the significance of sustainable water management practices and the need for continued monitoring and maintenance to ensure the safety and reliability of this essential infrastructure.

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.
