Summary
3 is a crucial federal irrigation structure located in Fremont, Wyoming, along the South Fork Little Wind River. Completed in 1935, this earth dam stands at 30 feet high with a structural height of 32 feet and a length of 724 feet. It serves the primary purpose of irrigation, providing essential water supply for agricultural activities in the region. With a storage capacity of 10,300 acre-feet and a normal storage capacity of 7,940 acre-feet, the dam plays a key role in managing water resources in the area.
The dam has a high hazard potential and is regulated by the State of Wyoming, with inspections conducted regularly to ensure its safety and effectiveness. Despite being designed primarily for irrigation purposes, Washakie Dike No. 3 also serves as a water supply source for the surrounding area. The dam's location in a scenic landscape adds to its significance, attracting water resource and climate enthusiasts who appreciate the importance of sustainable water management practices in the region.
Managed by the Sacramento District of the US Army Corps of Engineers, Washakie Dike No. 3 represents a vital piece of infrastructure that supports the agricultural community and helps regulate water flow in the area. Its role in preserving water resources and maintaining a sustainable environment underscores the importance of such structures in addressing the challenges posed by climate change and increasing water demand. As a critical component of the region's water infrastructure, Washakie Dike No. 3 continues to play a pivotal role in ensuring water security and environmental sustainability for future generations.

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.
