Summary

Built in 1924, this Earth dam stands at a height of 23 feet and has a normal storage capacity of 410 acre-feet. The dam, situated on Eagle Creek offstream, serves the primary purpose of irrigation, providing essential water resources for agricultural activities in the area.

Despite its age, Eagle Canyon Dam has been deemed to have a low hazard potential and is in poor condition as of the last assessment in 2017. However, with regular inspections and maintenance, the dam continues to serve its function effectively. The dam features an uncontrolled spillway with a width of 150 feet and a single valve outlet gate. Additionally, the dam has a moderate risk assessment level, indicating the need for ongoing risk management measures to ensure its safety and stability.

For water resource and climate enthusiasts, Eagle Canyon presents an intriguing case study of a historic irrigation dam in Wyoming. Its location in the picturesque Alcova region, along with its unique design features and operational history, make it a notable site for those interested in water infrastructure and management. As efforts continue to maintain and improve the dam's condition, Eagle Canyon serves as a reminder of the vital role that such structures play in supporting agricultural activities and water resource management in the region.

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.
