Summary

Completed in 1977, this earth dam stands at a height of 115 feet and has a maximum storage capacity of 24,400 acre-feet. The dam serves multiple purposes, including water supply, with a normal storage capacity of 18,300 acre-feet and a drainage area of 14.4 square miles.

With a hazard potential classified as high, Little Flint Creek Dam is closely regulated by the Arkansas Natural Resources Commission (ANRC). Despite being not rated in terms of condition assessment, the dam receives regular inspections, with the last one conducted in November 2016. The dam has a significant hydraulic height of 92 feet and a structural height of 105 feet, ensuring effective water management for the surrounding area.

As a crucial infrastructure in the region, Little Flint Creek Dam plays a key role in flood control and water supply management. Its location along the Little Flint Creek and proximity to Flint Ridge in Oklahoma make it a strategic asset for the community. With a maximum discharge capacity of 55,000 cubic feet per second, the dam is equipped to handle potential emergencies and ensure the safety of downstream areas.

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.
