Summary
1 is a privately owned Earth dam located in Torrington, Wyoming, along the Mule Creek. Built in 1942 for irrigation purposes, this structure stands at 29 feet high with a hydraulic height of 25 feet and a length of 185 feet. The dam has a storage capacity of 94 acre-feet, providing essential water resources for the surrounding area. Despite its age, Clay No. 1 is in fair condition and poses a low hazard potential, with a moderate risk assessment rating.
Maintained by the Wyoming State Engineer's Office, this dam is regularly inspected and meets state regulatory standards for operation and enforcement. With a spillway width of 300 feet and a single valve outlet gate, the structure is designed to handle controlled water discharge efficiently. In case of emergencies, the dam has a designated inspection frequency of 5 years, ensuring that any potential risks are promptly addressed.
Situated within the Congressional District 00 of Wyoming, Clay No. 1 plays a crucial role in providing water for irrigation, fire protection, stock, and small fish ponds in the region. With its stone core and soil foundation, this dam exemplifies a blend of traditional construction methods and modern engineering practices, safeguarding water resources for the community while maintaining a sustainable and environmentally conscious approach to water management.

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.
