Summary
Completed in 1925, this Earth dam stands at 30 feet high and spans 472 feet in length, with a storage capacity of 347 acre-feet. The dam is regulated and inspected by the Wyoming State Engineer's Office, ensuring its safe operation for irrigation purposes.
Despite its age, Orchard dam is rated as having a low hazard potential and fair condition assessment. The spillway, with a width of 5 feet, is uncontrolled, and the dam is equipped with a single valve outlet gate. The risk assessment for Orchard dam is moderate, indicating potential risks that are being managed through appropriate measures. With its historical significance and ongoing maintenance, Orchard continues to play a crucial role in the water resource management of Washakie County, Wyoming.
Water resource and climate enthusiasts will appreciate Orchard's unique design and operational features, as well as its connection to the local environment and agricultural activities. As a key infrastructure for irrigation in the region, Orchard dam serves as a reminder of the importance of sustainable water management practices and the need to continually assess and address potential risks associated with aging dams. With the proper regulatory oversight and maintenance, Orchard stands as a testament to the resilience and adaptability of water resource systems in the face of changing climates and environmental challenges.

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.
