Summary
This earth dam, completed in 1980, stands at a height of 9 feet and has a maximum storage capacity of 24 acre-feet. The dam primarily functions to store and supply water for various purposes, with a surface area of 4.6 acres and a drainage area of 0.1 square miles.
Managed by the Nevada Department of Water Resources, the dam is inspected regularly to ensure its structural integrity and safety. Despite its fair condition assessment in 2019, the dam poses a significant hazard potential, indicating the importance of proper risk management and emergency preparedness measures. With the Muddy River-OS flowing nearby, the dam plays a crucial role in water resource management and climate resilience efforts in the region.
As a key component of the local water supply system, Rgs Units 1-3 Raw Water Pond A Dam underscores the intersection of infrastructure, water resource management, and climate adaptation. With its strategic location and vital role in ensuring water security for Arrowhead and surrounding areas, the dam exemplifies the ongoing efforts to balance water supply needs with environmental conservation and risk mitigation in the face of changing climate patterns.

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.
