Summary
The dam, classified as an earth dam with a stone core and soil foundation, stands at a height of 12 feet with a hydraulic height of 8 feet and a structural height of 13 feet. It has a length of 1,411 feet and can store up to 783.7 acre-feet of water, with a normal storage capacity of 600 acre-feet.
The dam features an uncontrolled spillway with a width of 250 feet and outlet gates including two slide (sluice gate) and one uncontrolled gate. Despite its fair condition assessment and low hazard potential, Dacey Dam is subject to periodic inspections every five years to ensure its safety and functionality. The risk assessment for the dam is moderate, with a focus on implementing appropriate risk management measures to mitigate potential hazards and ensure the safety of the surrounding area.
With its scenic location and importance for fish and wildlife, irrigation, and recreation, Dacey Dam serves as a valuable water resource in the region. Managed by the Nevada Department of Water Resources, the dam plays a critical role in water management and conservation efforts in the area, making it a key site of interest for water resource and climate enthusiasts seeking to understand the intersection of infrastructure, natural resources, and environmental stewardship.

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.
