Summary

The dam, completed in 1995, stands at a height of 28 feet with a hydraulic height of 26 feet and a structural height of 30 feet. It serves primarily for flood risk reduction and is classified as an earth dam with a rockfill core and soil foundation.

With a storage capacity of 35.5 acre-feet, the dam has a low hazard potential and is in fair condition as of the last assessment in October 2021. Despite its moderate risk assessment rating, the dam has not had any modifications over the years and does not currently have any Emergency Action Plan (EAP) in place. The dam's spillway, an uncontrolled type with a width of 8 feet, has a maximum discharge capacity of 70 cubic feet per second.

Although the dam is not under the jurisdiction of the US Army Corps of Engineers, it is subject to state regulation, inspection, and enforcement by the Nevada Department of Water Resources. The dam poses a minimal risk to downstream communities and has not experienced any major incidents or breaches to date. It remains an essential structure for managing stormwater events and protecting the surrounding area from potential flooding.

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.
