Summary
Built in 1959, this Earth-type dam stands at 33 feet tall with a hydraulic height of 28 feet and a structural height of 32 feet. It serves multiple purposes, including fire protection, stock, and serving as a small fish pond. With a storage capacity of 88 acre-feet, Bob covers a surface area of 6 acres and has a spillway width of 40 feet.
Despite its low hazard potential, Bob has been assessed to be in poor condition as of September 2020. The dam has a moderate risk level, with a risk assessment rating of 3. It is regularly inspected every 5 years, with the last inspection conducted in September 2020. While there are no emergency action plans currently in place for Bob, the dam is regulated and permitted by the State of Wyoming, ensuring compliance with safety standards and enforcement measures.
Located in Johnson County, Bob's condition and risk level highlight the importance of ongoing maintenance and monitoring to ensure the safety and integrity of this vital water resource. For water resource and climate enthusiasts, Bob serves as a case study in the complex management and regulation of private dams in Wyoming, showcasing the intersection of environmental stewardship and public safety in the face of changing climate conditions.

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.
