Summary
Built in 1954, this dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a height of 23 feet and a length of 367 feet, the dam has a storage capacity of 81 acre-feet and covers a surface area of 8 acres.
Despite being classified as having a low hazard potential and fair condition assessment, Fivemile No.1 undergoes regular inspections every five years to ensure its structural integrity and safety. The dam features an uncontrolled spillway with a width of 200 feet and has no outlet gates. The risk assessment for this dam is moderate, indicating a moderate level of risk associated with its operation and maintenance.
Located within the jurisdiction of the State of Wyoming, Fivemile No.1 is regulated, permitted, inspected, and enforced by the State Engineer's Office. With Liz Cheney (R) as the Congressional representative for the area, this dam plays a crucial role in managing water resources for fire protection and agricultural purposes in the region. Enthusiasts of water resources and climate management will find Fivemile No.1 to be a fascinating example of a multi-purpose dam in the picturesque landscape of Wyoming.

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.
