Summary
This earth dam stands at a height of 25 feet with a hydraulic height of 21 feet, serving as a key component for controlling water levels in the Muddy River-TR. With a storage capacity of 264 acre-feet and a surface area of 13 acres, this dam plays a crucial role in managing water flow and storage in the region.
Owned and regulated by the Nevada Department of Water Resources, the Rgs Mesa Evaporation Pond M7 Dam is subject to regular inspections to ensure its structural integrity. The dam's hazard potential is considered significant, but its current condition is assessed as satisfactory. In the event of an emergency, the dam is equipped with outlet gates for controlled water release. With a high-risk assessment rating, measures for risk management and emergency preparedness are in place to mitigate any potential threats to the surrounding area.
As a public utility structure, the Rgs Mesa Evaporation Pond M7 Dam serves a critical purpose in water resource management, contributing to the overall sustainability of the region's water supply. With its strategic location and design features, this dam plays a pivotal role in maintaining water levels, controlling flow, and ensuring the safety and security of the surrounding community in Clark County, Nevada.

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.
