Summary

This reservoir, designed for flood risk reduction, sits on Bud Kimball Creek and has a storage capacity of 87.24 acre-feet, with a surface area of 7.08 acres and a drainage area of 1148.9 square miles. The dam, a gravity type with a hydraulic height of 26 feet and a structural height of 32 feet, plays a crucial role in mitigating potential flooding in the region.

Despite its low hazard potential, Crazy Rabbit Reservoir's condition assessment is currently marked as unsatisfactory, prompting a moderate risk rating. The last inspection in August 2016 revealed areas that require attention, emphasizing the importance of regular maintenance and monitoring to ensure the dam's safety. With Liz Cheney (R) as the representative for Congressional District 00, Wyoming, the reservoir's regulatory oversight falls under the State Engineer's Office, highlighting the collaborative effort between federal and state agencies in managing water resources and climate-related risks in the area.

As water resource and climate enthusiasts continue to monitor the evolving landscape of Crazy Rabbit Reservoir, it serves as a reminder of the intricate balance between human infrastructure and natural forces. With a history of federal ownership and ongoing regulatory oversight, this reservoir stands as a testament to the importance of proactive risk management and maintenance practices in safeguarding communities from potential water-related disasters. As climate change poses new challenges, the resilience and adaptability of structures like Crazy Rabbit Reservoir will be essential in ensuring the safety and sustainability of water resources for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
