Summary
Designed by Carol Chadwick and completed in 2006, this dam stands at a height of 26.7 feet with a maximum storage capacity of 42 acre-feet. Its primary purpose is flood risk reduction, serving the surrounding area by controlling water flow and protecting against potential inundation.
With a low hazard potential and fair condition assessment as of August 2017, Jim provides a moderate level of risk management for the community. The dam features an uncontrolled spillway with a width of 20 feet, and no outlet gates are present. Despite its simple design and construction, Jim plays a crucial role in maintaining water resources and climate stability in the region.
Located in a picturesque setting along Highway 59, Jim serves as a vital infrastructure for flood protection in the area. Regularly inspected and maintained, this dam ensures the safety of nearby residents and contributes to the overall water resource management efforts in Wyoming. For water resource and climate enthusiasts, Jim represents a significant piece of engineering that harmonizes with its natural surroundings to safeguard against potential environmental risks.

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.
