Summary
The dam, standing at 27 feet tall with a capacity of 40 acre-feet, primarily serves the purposes of fire protection, stock, and small fish pond. It is situated on Middle Creek, approximately 2.1 miles away from UNNAMED RANCH, and falls under the regulatory jurisdiction of the Wyoming State Engineer's Office.
With a low hazard potential and fair condition assessment, Cook Stock poses a moderate risk level that is managed through regular inspections every five years. The dam features an uncontrolled spillway, 3.69 acres of surface area, and a drainage area of 2.2 square miles. Despite its relatively small size, the structure has a maximum discharge capacity of 1060 cubic feet per second, ensuring efficient water management during peak flow events.
Overall, Cook Stock serves as a vital water resource for the surrounding area, providing essential services while maintaining a manageable risk level. Enthusiasts of water resources and climate will find this dam structure an intriguing example of how private ownership, regulatory oversight, and engineering design come together to support both functional and environmental needs in the region.

Dam Data Reference
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.
