Summary
This privately-owned earth dam stands at a height of 27 feet and has a hydraulic height of 22 feet. Completed in 1961, the dam has a storage capacity of 37 acre-feet and covers a surface area of 3 acres. Despite its low hazard potential, the structure is currently assessed as being in poor condition as of June 2018.
The "Road" dam on Tree Creek in Crook County, Wyoming, is regulated by the State of Wyoming, with inspection, permitting, and enforcement all carried out by the State Regulatory Agency (SEO). The structure has a spillway width of 20 feet and no outlet gates. Although the risk assessment deems the dam to have a moderate risk level, there are no emergency action plans (EAP) in place as of the last inspection date in June 2018. With a distance of 32 miles from Hulett and a drainage area of 0 square miles, this earth dam plays a vital role in the local ecosystem and community.
While the "Road" dam provides essential services such as fire protection and water storage, its current poor condition raises concerns for its long-term functionality and safety. With the dam being primarily used for recreational purposes and supporting local wildlife, it is crucial for stakeholders to collaborate on implementing necessary risk management measures and ensuring the structure's maintenance to prevent potential hazards and preserve the surrounding environment.

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.
