Summary

2, also known as Enl of 2600r, is a privately owned earth dam located in Hulett, Wyoming, on Bone Pile Creek. Built in 1916, this Stone core dam stands at a height of 29 feet and has a hydraulic height of 26 feet. With a length of 1209 feet and a storage capacity of 2501 acre-feet, Stone No. 2 serves primarily for irrigation purposes in the area. Despite being regulated by the state and inspected regularly, the dam's hazard potential is classified as low, with a fair condition assessment as of the last inspection in August 2018.

While Stone No. 2 has a moderate risk rating, with no emergency action plan (EAP) in place, it is crucial to ensure that proper risk management measures are implemented to mitigate any potential hazards. The dam's spillway type is uncontrolled, with a width of 100 feet, and it is equipped with one valve outlet gate. The surrounding area of Campbell County, Wyoming, relies on this dam for water storage and irrigation needs, making it essential to monitor and maintain its structural integrity to prevent any risks or emergencies. With Liz Cheney (R) representing the Congressional District 00, Wyoming, where Stone No. 2 is located, it is vital for stakeholders and authorities to work together to ensure the safety and sustainability of this crucial water resource infrastructure.

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.
