Summary
Constructed in 1962, this earth dam stands at 20 feet high with a length of 800 feet, providing a storage capacity of 269 acre-feet. Despite being classified as having a low hazard potential, Gardner is subject to state regulation, inspection, and enforcement to ensure its structural integrity and safety.
The dam's spillway, with a width of 78 feet, is uncontrolled, and the overall condition assessment as of August 2018 was deemed fair. While the risk assessment for Gardner is moderate, with a DSAC assigned date unspecified, the dam meets regulatory guidelines and has emergency action plans in place. Managed by the Omaha District of the US Army Corps of Engineers, Gardner plays a crucial role in managing water resources in the region and mitigating potential risks associated with its operation.
With Liz Cheney (R) representing Congressional District 00, Wyoming, where Gardner is situated, the dam continues to be a vital infrastructure asset for the local community. Its presence on Spring Creek not only supports agricultural activities through irrigation but also contributes to the overall water management efforts in the area. As climate change impacts continue to pose challenges to water resources, the proper maintenance and regulation of dams like Gardner are essential to ensuring water security and resilience in the face of a changing climate.

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.
