Summary
Built in 1922, this dam stands at a height of 10 feet and has a length of 1000 feet, providing a storage capacity of 537 acre-feet for irrigation purposes. Despite its importance for water resource management, the dam is currently assessed to be in poor condition, with a low hazard potential.
Managed by the Wyoming State Engineer's Office, Rainey is subject to state regulation, permitting, inspection, and enforcement. The dam has a history of periodic inspections, with the last assessment conducted in July 2017. With a designated inspection frequency of 5 years, it is crucial to ensure that necessary maintenance and repairs are carried out to mitigate any potential risks associated with its deteriorating condition.
Although Rainey has not been modified in recent years and is not classified as a US Army Corps of Engineers structure, its significance in supporting agricultural activities in the region underscores the importance of continued monitoring and maintenance to safeguard water resources and ensure the safety of downstream communities. Climate enthusiasts and water resource stakeholders should closely follow developments related to the condition and management of Rainey to support sustainable water management practices in the area.

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.
