Summary
This multipurpose structure also serves for flood risk reduction, with a height of 20 feet and a capacity of 296 acre-feet. Positioned along Dumbrill Creek, Barton plays a significant role in water resource management in the region, covering a surface area of 5.5 acres and having a spillway width of 30 feet.
Despite its low hazard potential, Barton's condition assessment was rated as poor during its last inspection in June 2019. The dam's poor condition raises concerns for its long-term reliability and ability to withstand potential hydrological events. With the dam located only 39 miles from Hulett and under the jurisdiction of the Wyoming State Engineer's Office, maintaining and improving Barton's structural integrity is crucial for ensuring the safety and sustainability of water resources in the area.
As a vital infrastructure for water storage and flood control, Barton presents challenges in terms of its maintenance and risk management. The dam's poor condition necessitates regular inspections and potential rehabilitation to enhance its safety and functionality. With proper maintenance and investment in risk reduction measures, Barton can continue to serve its purpose effectively while safeguarding the surrounding communities and ecosystems from potential water-related hazards.

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.
