Sand Dune Embankment Dam - South dam
Sand Dune Embankment Dam - South
Sand Dune Embankment Dam - South, also known as Boulder Valley Emergency Storm Pond #3, is a privately owned structure located in Eureka, Nevada, specifically in the city of DUNPHY. Completed in 1996, this earth dam stands at a height of 16 feet and has a hydraulic height of 13 feet, serving multiple purposes including Fish and Wildlife Pond, Flood Risk Reduction, and more. It is situated on Boulder Creek and has a drainage area of 48.5 square miles, with a maximum discharge capacity of 2034 cubic feet per second.
With a storage capacity of 2153 acre-feet, this dam covers a surface area of 589 acres and spans a length of 9655 feet. It features an uncontrolled spillway with a width of 30 feet and an outlet gate in the form of a single valve. Despite its low hazard potential, the condition of the dam has not been rated, and the last inspection took place in May 2020. The risk assessment categorizes it as moderate, indicating a certain level of risk management measures in place.
Located in Congressional District 02, Nevada, Sand Dune Embankment Dam - South plays a crucial role in mitigating flood risks and providing essential habitat for wildlife in the area. The Nevada Department of Water Resources regulates and inspects the dam regularly to ensure its safety and functionality. As a significant part of the local water resource infrastructure, this dam contributes to the overall water management efforts in the region and highlights the importance of sustainable water resource practices in the face of changing climate conditions.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Sand Dune Embankment Dam - South
Where does the data for Sand Dune Embankment Dam - South come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
