Summary
The primary purpose of this earth dam is for recreation, providing a storage capacity of 102 acre-feet and a surface area of 25.6 acres. Despite its low hazard potential, the dam has not been rated for its condition as of the last inspection in 2009.
Situated on Post Oak Creek-TR, the dam offers a tranquil setting for water resource and climate enthusiasts to enjoy various recreational activities. With a normal storage capacity of 83 acre-feet and a drainage area of 0.16 square miles, Lake Isabelle Dam serves as a haven for outdoor enthusiasts seeking to immerse themselves in nature. Although not regulated by the state, the dam's location in Rector, Arkansas, ensures easy access for visitors looking to explore the surrounding area.
Managed by a private owner, Lake Isabelle Dam poses little risk to the surrounding community, as indicated by its low hazard potential. While not currently rated for its condition, the dam provides a safe and enjoyable environment for individuals looking to engage in water-based activities. With its serene surroundings and ample storage capacity, the dam offers a unique opportunity for water resource and climate enthusiasts to appreciate the beauty of the Arkansas landscape.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
