Summary
1 is a privately owned irrigation dam located in Niobrara, Wyoming, along the Wildcat Draw river. Built in 1953, this earth dam stands at a height of 40 feet and has a storage capacity of 327 acre-feet, serving the primary purpose of irrigation. Despite being regulated and inspected by the Wyoming State Engineer's Office, the dam is rated with a low hazard potential and fair condition assessment, with a moderate risk level.
This uncontrolled spillway dam features a spillway width of 200 feet and an outlet gate in the form of a slide (sluice gate). With a drainage area of zero and a surface area of 19 acres, Wildcat No. 1 has been deemed to have a moderate risk level, indicating the need for careful risk management measures. Located in a congressional district represented by Liz Cheney (R), this dam plays a crucial role in water resource management in the region, highlighting the intersection of water resources and climate issues in the area.
Despite its low hazard potential, Wildcat No. 1 serves as a vital infrastructure for irrigation in the region, showcasing the importance of maintaining and monitoring such water resource structures. With a focus on risk assessment and management, this dam underscores the need for proactive measures to ensure the safety and sustainability of water resources in the face of changing climate 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.
