Summary
Built in 1970 by the local government, this earth dam serves a primary purpose of water storage with a height of 8 feet and a length of 1220 feet. With a normal storage capacity of 8 acre-feet and a maximum capacity of 61 acre-feet, the dam plays a crucial role in regulating water flow in the Humboldt River-OS.
Despite its age, Winnemucca Lagoon #6 Dam remains in fair condition with a low hazard potential. The dam is state-regulated by the Nevada Department of Water Resources, ensuring regular inspections and enforcement of safety measures. With one controlled outlet gate and no spillway, the dam is designed to withstand potential risk factors and ensure the safety of surrounding areas. The risk assessment for the dam is classified as high (2), prompting the need for continued monitoring and management to mitigate any potential threats.
As a key infrastructure in the region, Winnemucca Lagoon #6 Dam serves as a valuable resource for water management and climate resilience. With its strategic location and sound construction, the dam plays a critical role in supporting the water needs of the community while also addressing potential risks and hazards. As water enthusiasts and climate advocates continue to focus on sustainable resource management, this dam stands as a symbol of effective governance and proactive measures in safeguarding water resources for future generations.

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.
