Summary
Completed in 2008, this earth dam stands at a height of 27 feet and has a hydraulic height of 20 feet, with a structural height of 35 feet. The dam stretches 380 feet in length and has a storage capacity of 268 acre-feet.
Managed by local government authorities and regulated by the Nevada Department of Water Resources, the dam is designed to control debris and mitigate flood risks in the region. With a spillway width of 380 feet and a maximum discharge capacity of 25,000 cubic feet per second, the dam plays a vital role in safeguarding the surrounding area during heavy rainfall events. Despite its high hazard potential, the dam's current condition is assessed as fair, with regular inspections ensuring its operational readiness.
With its strategic location and design, Abbott Wash Detention Basin Dam stands as a testament to effective flood risk management and water resource conservation in the region. As climate change continues to impact weather patterns and water availability, the dam's role in protecting communities and infrastructure from potential flooding events becomes increasingly essential. Through ongoing monitoring and maintenance efforts, this dam remains a crucial asset in ensuring the safety and resilience of the local area in the face of changing environmental conditions.

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.
