Summary

2, located in Torrington, Wyoming, is a privately owned earth dam built in 1968 for flood risk reduction along the Ashenhurst Draw. With a structural height of 35 feet and a hydraulic height of 29 feet, this dam serves a critical purpose in protecting the surrounding area from potential flooding events. The dam has a normal storage capacity of 28 acre-feet and a maximum storage capacity of 48 acre-feet, covering a surface area of 2.92 acres.

Despite its low hazard potential and fair condition assessment as of the last inspection in 2017, Hal No. 2 poses a moderate risk level, emphasizing the importance of continued monitoring and maintenance. The dam features an uncontrolled spillway type with a width of 35 feet and one other controlled outlet gate for water discharge. With state regulation, inspection, and enforcement in place, along with a designated emergency action plan, the dam is equipped to respond effectively to any potential risks or emergencies. Overall, Hal No. 2 stands as a vital infrastructure contributing to water resource management in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
