Summary

is a privately owned earth dam located in Coyle, Oklahoma, within Logan County. Completed in 1965, this structure stands at a height of 30 feet and has a length of 510 feet, providing a storage capacity of 180 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to regular inspections, with a low hazard potential and a condition assessment that is currently not rated.

The primary purpose of Ran Rick Jr. is categorized as "Other," with a spillway type of "Controlled" and a maximum discharge capacity of 2200 cubic feet per second. The dam is equipped with a valve outlet gate and is located on the TR-Wolf Creek river/stream. Despite its low hazard potential, the risk assessment for Ran Rick Jr. indicates a very high risk level (1), emphasizing the importance of continued monitoring and maintenance to ensure the safety and effectiveness of the structure.

Overall, Ran Rick Jr. serves as an essential water resource management tool in the region, playing a crucial role in flood control and water storage. With its strategic location and design features, this earth dam contributes to the overall resilience of the surrounding area against water-related challenges, making it a significant asset for water resource and climate enthusiasts to study and appreciate.

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.
