Summary
Terry Lock and Dam, also known as Pool 6, is a federal water resource structure located in Pine Bluff, Arkansas. Completed in 1968 by the US Army Corps of Engineers, this concrete gravity dam on the Arkansas River serves primarily for navigation purposes, with a single lock facilitating vessel passage. With a height of 51 feet and a length of 8,700 feet, the dam also offers recreational opportunities in its 4,710-acre surface area.
The dam's risk assessment indicates a very high potential for hazard, prompting the USACE to implement rigorous risk management measures. Continuous monitoring, prioritized maintenance activities, and collaboration with local emergency managers and the public are integral to mitigating flood risks associated with the dam. The emergency action plan is regularly updated, and the USACE remains committed to ensuring the structural integrity and functionality of the David D. Terry Lock and Dam to safeguard against potential emergencies.

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.
