Summary
Built in 1910, this earth dam stands at 11 feet tall and spans 650 feet in length along Porcupine Creek. With a normal storage capacity of 96 acre-feet and a maximum storage of 166 acre-feet, the Reno Dam plays a crucial role in supplying water for agricultural needs in the region.
Despite its age, the Reno Dam remains in fair condition with a low hazard potential. It is equipped with two slide (sluice gate) outlet gates and an uncontrolled spillway measuring 50 feet in width. The dam has been inspected as recently as April 2020, with a frequency of inspections set at every five years. With a moderate risk assessment rating of 3, the Reno Dam is subject to state regulation, inspection, and enforcement to ensure its continued functionality and safety for the surrounding community.
In the event of an emergency, the Reno Dam has protocols in place to address potential risks, although specific details on emergency action plans and inundation maps are not readily available. With Liz Cheney serving as the Congressional representative for the area, the Reno Dam serves as a vital piece of infrastructure in maintaining water resources and supporting the local economy through irrigation and water supply.

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.
