Summary

Built in 1962 by USDA SCS, this earth dam stands at 21 feet high with a hydraulic height of 14 feet and a structural height of 22 feet. With a length of 2425 feet and a storage capacity of 640 acre-feet, the dam plays a crucial role in managing water flow and protecting the surrounding area from potential hazards.

Managed by the Nevada Department of Water Resources, Hollinger Debris Dam is regulated, inspected, and enforced to ensure its optimal performance. Despite being categorized as having a low hazard potential, the dam's condition assessment in 2018 was rated as fair, with a moderate risk level assigned. The dam features an uncontrolled spillway with a width of 69 feet and one uncontrolled outlet gate, providing essential emergency water release capabilities.

For water resource and climate enthusiasts, Hollinger Debris Dam stands as a testament to effective flood risk management and debris control in the region. With its strategic location and design, the dam continues to play a crucial role in safeguarding the local community and environment from potential water-related disasters. Through regular inspections and maintenance, the dam remains a reliable asset in the state's water infrastructure, showcasing the importance of proactive risk management and emergency preparedness in safeguarding water resources.

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. 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

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, 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.
