Summary
The dam stands at a height of 32 feet, with a hydraulic height of 27 feet and a structural height of 32 feet. It spans 191 feet in length and has a storage capacity of 32 acre-feet, with a normal storage level of 19 acre-feet. The dam is situated on the East Fork Pugsley Draw and is regulated by the State of Wyoming, with permitting, inspection, and enforcement conducted by the State Engineer's Office.
Despite its low hazard potential and fair condition assessment, Murk Stock poses a moderate risk, ranking a 3 on the risk assessment scale. The dam features an uncontrolled spillway with a width of 40 feet and has no outlet gates. The last inspection was conducted in April 2017, with a scheduled inspection frequency of every 5 years. The dam's emergency action plan status, inundation maps, and risk management measures are currently unspecified, highlighting areas for potential improvement in emergency preparedness.
In the heart of Wyoming's picturesque landscape, Murk Stock serves as a vital resource for fire protection and stock water supply. With its unique blend of functionality and natural beauty, this earth dam stands as a testament to sustainable water resource management in the region, while also underscoring the importance of ongoing monitoring and maintenance to ensure the safety and security of the surrounding community and ecosystem.

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.
