Summary
Completed in 1996, this earth dam stands at a height of 14 feet and has a hydraulic height of 10 feet, serving purposes such as Fish and Wildlife Pond, Flood Risk Reduction, and others. The dam has a storage capacity of 1045 acre-feet and covers a surface area of 361 acres, with a drainage area of 48 square miles.
Situated on BOULDER CREEK in Eureka County, Nevada, this dam plays a crucial role in managing water resources and mitigating flood risks in the area. It features an uncontrolled spillway with a width of 40 feet and is equipped with a slide (sluice gate) outlet gate. Despite being rated as having a low hazard potential, the dam's condition assessment remains unrated as of the last inspection in May 2020. With moderate risk associated with its operations, the Sand Dune Embankment Dam - Center is monitored and regulated by the Nevada Department of Water Resources to ensure its safety and compliance with state standards.
Overall, the Sand Dune Embankment Dam - Center serves as a vital infrastructure for water management and flood control in the region, providing essential benefits for wildlife, water storage, and risk reduction. Its strategic location and design contribute to the overall water resource management efforts in Nevada, highlighting the importance of maintaining and monitoring such critical structures for long-term sustainability and resilience to climate challenges.

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.
