Summary
This earth-type dam, completed in 2011, serves a primary purpose of regulating water resources in the area through its 260-acre-feet storage capacity. With a structural height of 51 feet and a hydraulic height of 47 feet, this dam plays a crucial role in water management for the Muddy River-TR watershed.
Despite its fair condition assessment as of April 2019, the Rgs Mesa Evaporation Pond M5 Dam poses a significant hazard potential, emphasizing the need for regular inspections and maintenance. The dam, with a surface area of 12.9 acres, holds a normal storage capacity of 219.9 acre-feet, supporting the local ecosystem and water supply needs. With the Nevada Department of Water Resources as the state regulatory agency overseeing its operations, the dam is subject to state permitting, inspection, and enforcement, ensuring its functionality and safety.
With a risk assessment rating of "High (2)" and a hazard potential that cannot be ignored, the Rgs Mesa Evaporation Pond M5 Dam serves as a critical infrastructure in water resource management for the region. As climate change continues to impact water availability and quality, maintaining and monitoring such structures becomes increasingly vital for ensuring the resilience of communities and ecosystems in the face of evolving environmental challenges.

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.
