Summary
The dam, completed in 1960, stands at a height of 8 feet and has a structural height of 10 feet, with a length of 1940 feet. Designed primarily for earth materials with a stone core and soil foundation, the dam has a storage capacity of 58 acre-feet, with normal storage levels reaching 36 acre-feet.
Managed by the local government and regulated by the Nevada Division of Water Resources, Carlin Wwtp Treatment Lagoon Cell 2 Dam plays a vital role in maintaining water quality and ensuring the safe operation of the treatment lagoon. With a low hazard potential but a high risk assessment rating due to its age and condition assessment not rated, the dam undergoes regular inspections every 5 years to monitor its structural integrity and overall performance. While no spillway is present, the dam is equipped with a single valve outlet gate for controlled water release.
Despite its age and risk assessment, Carlin Wwtp Treatment Lagoon Cell 2 Dam continues to provide essential wastewater treatment services for the community of Carlin and plays a significant role in water resource management in the region. With its strategic location along the Humboldt River, the dam serves as a critical infrastructure asset for safeguarding water quality and ensuring the sustainable use of water resources in Elko County.

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.
