Summary
The dam stands at a height of 13 feet, with a hydraulic height of 8 feet and a length of 760 feet, providing a storage capacity of 278 acre-feet. Despite being categorized as having a low hazard potential, the dam's condition assessment is poor, indicating a need for maintenance and repairs.
With a spillway width of 200 feet and an uncontrolled spillway type, Wales has a moderate risk level (3) associated with its operation. The dam is inspected every five years, with the last assessment conducted in March 2020. Although the dam has not been significantly modified over the years, its poor condition raises concerns about its long-term sustainability and ability to withstand potential climate-related challenges.
Given its importance for irrigation in the region, stakeholders and authorities need to address the dam's maintenance needs promptly to ensure its safety and functionality. With the potential for climate change to impact water resources in the area, proactive risk management measures should be implemented to mitigate any potential hazards associated with Wales and other critical water infrastructure in Wyoming.

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.
