Summary
Operated by a public utility, the dam is regulated by the Nevada Department of Water Resources and inspected by the Federal Energy Regulatory Commission. With a height of 78 feet and a storage capacity of 171,000 acre-feet, Rye Patch plays a crucial role in water management and energy production in the region.
Despite its importance, Rye Patch poses a high hazard potential, with a very high risk assessment rating. The dam features a controlled spillway and five Tainter (radial) outlet gates, ensuring controlled water release in case of emergencies. Although condition assessment data is not currently available, the dam is subject to regular inspections and emergency action plans to mitigate potential risks and ensure public safety.
Managed by the Sacramento District of the US Army Corps of Engineers, Rye Patch represents a significant infrastructure project in the region. The dam's location and design make it a key player in water resource management and climate resilience efforts in Nevada. As water resource and climate enthusiasts, understanding the critical role of structures like Rye Patch in sustainable development and risk management is essential for safeguarding our environment and communities.

Dam Data Reference
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.
