Summary

The dam, completed in 1960, is an earth structure with a height of 16 feet and a length of 695 feet, providing a maximum storage capacity of 110 acre-feet. The lake is situated on a tributary of the Little River and is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.

Despite its low hazard potential, Reynolds Lake is considered to have a very high risk due to its surrounding area and the potential impact of a dam failure. The reservoir is equipped with a controlled spillway and a valve outlet gate for water management. The last inspection of the dam took place in February 2001, with a scheduled inspection frequency of 5 years. While the condition assessment is currently not rated, the risk management measures and emergency action plans for the reservoir are not specified in the available data.

Overall, Reynolds Lake serves as a vital water resource for the local community, offering recreational opportunities and environmental benefits. Its management and regulation by state authorities ensure safe operation and maintenance of the dam, contributing to water conservation efforts and climate resilience in the region. Enthusiasts of water resources and climate conservation can appreciate the importance of Reynolds Lake in balancing the needs of recreation with the preservation of natural resources.

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.
