Summary
Completed in 1910, this irrigation dam stands at a height of 11 feet and has a hydraulic height of 8 feet, with a length of 877 feet. The dam has a storage capacity of 204 acre-feet, with a normal storage level of 142 acre-feet and a surface area of 30 acres.
Despite being classified as having a low hazard potential, Greyhound is considered to be in fair condition as of its last inspection in September 2020. The dam is equipped with an uncontrolled spillway and one other controlled outlet gate. The risk assessment for this dam is moderate, with a risk level of 3 out of 5. Although no emergency action plan is currently in place, the dam is regularly inspected by state authorities, with enforcement and permitting also being handled at the state level.
Overall, Greyhound serves as a vital irrigation structure in the region, providing water resources for agricultural purposes. With its historic significance and continued functionality, this dam stands as a testament to the importance of water management in sustaining the local ecosystem and supporting the agricultural community in Carbon County, 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.
