Summary
Completed in 1967, this earth dam stands at 18 feet in height and spans a length of 1893 feet, with a storage capacity of 1120 acre-feet. The dam's primary purpose as a fish and wildlife pond is complemented by its role in providing irrigation water and recreational opportunities in the region.
Managed by the Nevada Department of Water Resources, Hay Meadow Dam boasts a low hazard potential and fair condition assessment, ensuring the safety and functionality of the structure. The dam is equipped with an uncontrolled spillway, with a width of 400 feet, and an outlet gate for controlled water release. Regular inspections, conducted every 5 years, help to maintain the dam's integrity and safeguard against potential risks, with the most recent assessment taking place in April 2021.
With its strategic location along the White River, Hay Meadow Dam plays a crucial role in water resource management and ecological preservation in the area. As a key component of the local infrastructure, the dam exemplifies the intersection of human engineering and environmental conservation, highlighting the importance of sustainable water management in the context of climate change and evolving hydrological dynamics.

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.
