Summary
This flood risk reduction structure stands at a height of 35 feet with a hydraulic height of 31 feet and a structural height of 36 feet. With a dam length of 530 feet and a storage capacity of 694 acre-feet, it serves as a vital asset for managing floodwaters in the area, particularly during peak flow events.
Despite its critical role in flood risk reduction, Barrel Floodwater Detention is currently assessed as being in poor condition, with a low hazard potential. The dam features an uncontrolled spillway with a width of 150 feet and a valve outlet gate. The structure is state-regulated and inspected regularly by the Wyoming State Engineer's Office, ensuring its functionality and safety for the surrounding community. With a moderate risk assessment rating, there is a need for ongoing risk management measures to maintain the dam's effectiveness in mitigating flood impacts in the region.
As water resource and climate enthusiasts, the Barrel Floodwater Detention presents an intriguing case study in the intersection of infrastructure, water management, and climate resilience. By understanding the design, condition, and regulatory framework of this flood control structure, stakeholders can work towards enhancing its performance and ensuring its continued ability to protect lives and property from flood hazards. With a commitment to regular inspections, maintenance, and risk assessment, Barrel Floodwater Detention serves as a valuable resource in mitigating flood risks in Weston, Wyoming, and beyond.

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.
