Summary
Completed in 1989, this dam serves multiple purposes including recreation, tailings containment, and water supply. With a storage capacity of 200 acre-feet and a surface area of 11 acres, the dam sits on Willow Creek and has a drainage area of 6 square miles.
Managed by the Nevada Department of Water Resources, Bmg Mine Willow Creek Dam has a spillway width of 40 feet and an uncontrolled spillway type. The dam's condition assessment is rated as fair, with a significant hazard potential and a moderate risk assessment score of 3. The last inspection was conducted in May 2020, with inspections occurring every 3 years. The dam is equipped with a slide (sluice gate) outlet gate for water release in case of emergencies.
Despite its modest size, Bmg Mine Willow Creek Dam plays a crucial role in the local ecosystem and water management. Its strategic location on Willow Creek ensures a stable water supply for surrounding areas while also providing recreational opportunities for residents and visitors alike. As climate change continues to impact water resources, the maintenance and monitoring of dams like Bmg Mine Willow Creek Dam will be essential to ensure their safety and functionality in the face of evolving environmental conditions.

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.
