Summary
Completed in 1951, this earth dam stands at 32 feet high and has a storage capacity of 577 acre-feet. Despite its age, Boggy has been maintained with regular inspections and enforcement of state regulations to ensure its safety and functionality for agricultural purposes. The dam's spillway width of 125 feet and low hazard potential indicate a moderate risk level, prompting ongoing risk management measures to safeguard the surrounding area.
Situated in Congressional District 00 of Wyoming, Boggy serves as a vital water resource for the local community, particularly during dry spells. Its poor condition assessment in 2017 highlights the need for potential upgrades or repairs to enhance its resilience to climate variability and future water demands. While the dam currently meets state permitting and regulatory requirements, ongoing monitoring and risk assessments are crucial to mitigate any potential hazards and ensure the long-term sustainability of Boggy as a key irrigation infrastructure in the region. For water resource and climate enthusiasts, Boggy presents an intriguing case study of balancing agricultural water needs with dam safety and environmental considerations in a changing climate.

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.
