Summary

Built in 1970, the Earth-type dam stands at a height of 185 feet and has a storage capacity of 38,720 acre-feet, serving the primary purpose of irrigation. The dam underwent modifications in 1996 to enhance its hydraulic, structural, and operational aspects.

Managed by the Bureau of Reclamation, Meeks Cabin has a high hazard potential and a moderate risk assessment rating. The dam features uncontrolled spillways and a combination of outlet gates for water release. Despite its condition assessment being listed as not available, the dam is inspected annually, with the last inspection conducted in July 2020 to ensure its safety and functionality.

Situated in Uinta County, Wyoming, Meeks Cabin plays a crucial role in water resource management in the region, providing irrigation water for agricultural activities. With its strategic location and significant storage capacity, the dam serves as a vital infrastructure for maintaining water availability and supporting the local ecosystem amidst changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
