Summary
Owned by the local government, this pond serves the primary purpose of flood risk reduction along the Airport Draw river. Completed in 1993, this earth dam stands at a height of 17 feet and has a hydraulic height of 14 feet, providing a storage capacity of 31 acre-feet to mitigate flood risks in the area.
With a significant hazard potential and fair condition assessment, the Basin No.2 Flood Detention Pond plays a crucial role in managing water flow and reducing flooding risks in Natrona County. This uncontrolled spillway structure boasts a width of 22 feet and has an outlet gate for controlled water release. The pond covers a surface area of 6 acres and has a drainage area of 0.3 square miles, ensuring effective water retention and discharge during peak flow events.
Despite its fair condition, regular inspections and maintenance ensure the functionality and reliability of Basin No.2 Flood Detention Pond. With a moderate risk assessment level, this structure continues to play a key role in water resource management and climate resilience efforts in the region. As a vital component of flood risk reduction strategies, this pond stands as a testament to effective water infrastructure design and operation in Wyoming.

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.
