Summary
Smith is a Federal-owned dam located in Cokeville, Wyoming, along the South Fork Twin Creek. Built in 1922, this earth dam serves multiple purposes, including fire protection, stock watering, and small fish pond management. With a height of 20 feet and a length of 805 feet, the dam has a storage capacity of 122 acre-feet and a surface area of 18 acres.
Despite its low hazard potential, C.H. Smith is currently in poor condition as of the last inspection in October 2019. The dam has an uncontrolled spillway and one other controlled outlet gate. While the risk assessment indicates a moderate level of risk, there are no specific risk management measures mentioned in the data. It is essential for water resource and climate enthusiasts to keep a close eye on the maintenance and condition of C.H. Smith to ensure its continued safety and functionality for the surrounding community.
Overall, C.H. Smith represents a vital piece of infrastructure for the area, providing essential services for fire protection, agriculture, and wildlife management. As part of the Federal system, it falls under the jurisdiction of the State of Wyoming and is subject to state regulations and inspections. With a rich history dating back to the early 20th century, C.H. Smith stands as a testament to the importance of water resource management and the ongoing need for monitoring and maintenance to ensure its continued efficacy and safety.

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.
