Summary

Built in 1968 for hydroelectric purposes, this dam stands at 15 feet high and stretches 3000 feet in length, with a storage capacity of 48,225 acre-feet. The dam is primarily constructed with buttress and stone core types on a rock foundation, making it a significant water resource infrastructure in the area.

Managed by the Federal Energy Regulatory Commission, Rim Dike 1 is classified as a high hazard potential structure with limited condition assessment data available. Despite its age, the dam continues to play a crucial role in water management and power generation in the region. With its strategic location and purpose, Rim Dike 1 serves as a key component in Oklahoma's water resource infrastructure, ensuring the safety and reliability of water supply for both agricultural and urban needs.

Although lacking detailed risk assessment and emergency preparedness information, Rim Dike 1 remains an essential structure for water and climate enthusiasts to study and monitor. Its historical significance, engineering design, and operational impact make it a fascinating subject for those interested in water resource management and climate resilience efforts in the Oklahoma region.

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.
