Summary
Completed in 1967, this Earth type dam stands at a height of 55 feet with a hydraulic height of 46 feet, serving as a crucial water resource for the region. With a storage capacity of 1100 acre-feet and a normal storage of 500 acre-feet, the dam plays a vital role in providing water for irrigation, fire protection, stock, and small fish ponds.
Managed by the Nevada DWR, Round Mountain Reservoir Dam has a low hazard potential and is currently assessed to be in fair condition as of June 2018. With a moderate risk rating, the dam is inspected every five years to ensure its structural integrity and safety. The dam's spillway type is uncontrolled, with a width of 12 feet, and an outlet gate consisting of a single valve. Despite its low hazard potential, the dam remains a critical infrastructure for water management in the area, supporting the local ecosystem and agricultural activities.
In the Congressional District 02 of Nevada, Round Mountain Reservoir Dam is a notable feature along Spring Creek, with a surface area of 53.5 acres and a drainage area of 3.7 square miles. The dam has a maximum discharge capacity of 950 cubic feet per second and is subject to state regulations and inspections to maintain its operational efficiency. As a key component of the region's water management system, the dam continues to play a significant role in ensuring water security and resource sustainability for the community.

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.
