Summary
Built in 1963, this earth dam stands at a height of 26 feet and has a storage capacity of 167 acre-feet. With a surface area of 15 acres and a drainage area of 0, Jessie primarily regulates water from the Prarie Creek to ensure adequate water supply for its intended uses.
Despite its low hazard potential and fair condition assessment, Jessie is subject to state regulation and inspection to ensure its safety and functionality. The dam features an uncontrolled spillway with a width of 96 feet and is equipped with outlet gates for water release. Its last inspection in July 2018 deemed it to have moderate risk, prompting the need for regular monitoring and potential risk management measures to mitigate any potential issues.
Situated in the Omaha District of Wyoming, Jessie serves as a crucial water resource for the local community and wildlife. Its location on the Prarie Creek, along with its role in fire protection and stock watering, highlights its significance in the region's water management and climate resilience efforts. Enthusiasts of water resources and climate will find Jessie's design and purpose intriguing, showcasing the intricate balance between human needs and environmental conservation.

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.
