Summary
Completed in 1923, this concrete gravity dam stands at a height of 27 feet and serves the primary purpose of irrigation along the Wind River. With a storage capacity of 400 acre-feet and a drainage area of 1860 acres, the dam plays a crucial role in supporting agricultural activities in the region.
Managed by the Bureau of Reclamation, the Wind River Diversion has a low hazard potential and is regularly inspected to ensure its structural integrity and safety. While the condition assessment is currently listed as "Not Available," the dam is regulated, permitted, inspected, and enforced by various state agencies, including the State Engineer's Office. Despite its age, the dam continues to provide essential water resources for irrigation, highlighting its importance in sustaining agricultural practices in the area.
With Liz Cheney representing the region in Congress, the Wind River Diversion underscores the intersection of water resource management, climate resilience, and agricultural sustainability. As water resource and climate enthusiasts, understanding the significance of this infrastructure sheds light on the ongoing efforts to balance water allocation for irrigation while mitigating potential risks and ensuring long-term water security for the community.

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.
