Summary
This earth dam stands at a height of 27 feet with a hydraulic height of 16 feet, and a length of 18,770 feet, providing a storage capacity of 1,837 acre-feet. The dam features a slide (sluice gate) outlet with five gates and an uncontrolled spillway width of 3,050 feet.
With a hazard potential rated as high and a fair condition assessment as of May 2021, the Coyote Springs Detention Basin 1-2 Dam plays a crucial role in flood risk reduction in the region. The dam is state-regulated by the Nevada Department of Water Resources, ensuring that it meets necessary inspection, enforcement, and permitting requirements. While the risk assessment for the dam is moderate, it highlights the importance of ongoing monitoring and maintenance to ensure its effectiveness in protecting the surrounding area from potential inundation events.
As an essential infrastructure for water resource management in Clark County, Nevada, the Coyote Springs Detention Basin 1-2 Dam serves as a key component in the overall flood control strategy for the region. Its strategic location along the Pahranagat Wash and its sturdy design make it a vital asset in safeguarding communities and property against the impacts of extreme weather events. Climate enthusiasts and water resource professionals alike can appreciate the role this dam plays in enhancing resilience to climate change and ensuring sustainable water management practices in the area.

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.
