Summary
This earth dam stands at 74 feet high and spans 1452 feet in length, with a primary purpose of flood risk reduction along the Eight Mile Creek. The dam has a high hazard potential and fair condition assessment, with a storage capacity of 944 acre-feet and a maximum discharge of 4575 cubic feet per second.
The dam features an uncontrolled spillway with a width of 125 feet and one uncontrolled outlet gate. It is regulated by the Nevada Division of Water Resources and undergoes regular inspections, with the last one conducted in October 2021. Despite its moderate risk assessment rating, the dam meets state permitting and enforcement requirements, ensuring its structural integrity and overall safety for the surrounding community.
Eight Mile Creek Dam serves as a vital infrastructure for managing flood risks in the region and plays a crucial role in protecting the area from potential inundation. With its strategic location and design, the dam provides essential flood control measures and contributes to the overall water resource management efforts in Elko, Nevada. For water resource and climate enthusiasts, this dam represents a significant investment in safeguarding the local environment and enhancing resilience to natural disasters.

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.
