Summary
2 is a significant earth dam located in Fremont, Wyoming, along the South Fork Little Wind River. Completed in 1935, this Federal-owned structure serves primarily for irrigation purposes, with a maximum storage capacity of 10,300 acre-feet. The dam stands at a height of 23 feet, with a structural height of 25 feet and a hydraulic height of 18 feet, safeguarding a drainage area of 92 square miles.
With a high hazard potential, Washakie Dike No. 2 is subject to state regulation, inspection, and enforcement by the Wyoming State Engineer's Office. The dam's condition assessment remains unrated, highlighting the need for continued monitoring and maintenance. The last inspection in 2017 underscored the importance of regular assessments to ensure the safety and integrity of the structure.
As a crucial water resource in the region, Washakie Dike No. 2 plays a vital role in supporting irrigation and water supply needs. With its historical significance and essential function, the dam represents a key piece of infrastructure in managing water resources and climate impacts in the area. Ongoing efforts to maintain and assess the dam's condition are essential to safeguarding its role in water management and environmental stewardship.

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.
