Coyote Reservoir Report
Last Updated: March 24, 2026
Coyote is a privately owned earth dam located in Uinta, Wyoming, with a primary purpose of irrigation.
Summary
Built in 1962, the dam stands at a height of 8 feet and has a hydraulic height of 5 feet, with a structural length of 360 feet. The dam is situated on Coyote Spring, serving as a vital water resource for the surrounding area.
Despite its low hazard potential, Coyote Dam is in poor condition as of the last inspection in November 2017. The dam has a normal storage capacity of 74 acre-feet and a surface area of 14 acres. With an uncontrolled spillway type and one valve outlet gate, the dam poses a moderate risk (rating of 3) in terms of its overall safety. It is crucial for water resource and climate enthusiasts to monitor and address the maintenance and rehabilitation needs of Coyote Dam to ensure its continued functionality and safety for irrigation purposes 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.
