Summary

Built in 1939, this earth dam stands at a towering height of 66 feet and stretches 1750 feet in length. With a maximum storage capacity of 395 acre-feet and a normal storage level of 353 acre-feet, the dam serves as a crucial source of water for the residents of Little Rock and surrounding areas.

Regulated by the Arkansas Natural Resources Commission (ANRC), the Jackson Reservoir Dam is equipped with state-of-the-art inspection, enforcement, and permitting protocols to ensure its safety and functionality. Despite being classified as having a high hazard potential, the dam's condition assessment is listed as "Not Rated," indicating the need for further evaluation. The dam's emergency action plan (EAP) status and risk management measures are currently unreported, raising questions about its readiness in the face of potential emergencies.

Climate and water resource enthusiasts will find the Jackson Reservoir Dam an intriguing subject for study, given its historical significance, high hazard potential, and state-regulated status. As discussions surrounding water security and dam safety continue to gain importance in the face of climate change, understanding the intricacies of dams like Jackson Reservoir becomes increasingly crucial for ensuring the resilience of water supply systems in the 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.
