Summary
The facility, designed by Dustin Rougeau, features an earth dam with a height of 24 feet and a storage capacity of 140 acre-feet. Completed in 2020, this project serves multiple purposes and is regulated by the Wyoming State Engineer's Office, with state permitting, inspection, and enforcement in place to ensure compliance and safety.
With a low hazard potential and satisfactory condition assessment, Nighthawk Facility is deemed to have a high risk level, prompting the need for risk management measures. Although the dam does not have a spillway or outlet gates, its design includes stone core and soil foundation to support its structural integrity. The facility has a surface area of 11.3 acres and a maximum storage capacity of 140 acre-feet, catering to the water needs of the area while maintaining a safe and reliable water resource infrastructure.
Situated in a picturesque location in Wyoming, Nighthawk Facility - Phase 2 (Pit3) & Phase 3 (Pit 4) represents a vital component of the state's water resource management efforts. With its modern design, efficient operation, and adherence to regulatory standards, this private facility serves as a testament to the importance of sustainable water infrastructure development in the face of changing climate conditions.

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.
