Summary
This Earth-type dam stands at a height of 15 feet with a hydraulic height of 11 feet, spanning a length of 437 feet along Cypress Creek. Despite being classified as low hazard potential and not being state-regulated, this dam provides essential functions for the local community in Conway.
With a storage capacity of 107 acre-feet and a maximum discharge of 1013 cubic feet per second, Gentry Lake Dam plays a crucial role in managing water resources in the area. While its condition assessment is currently not rated, the dam serves as a valuable asset for recreational activities and wildlife conservation. Although not under the jurisdiction of state regulatory agencies, this dam exemplifies the importance of private ownership in maintaining and managing water infrastructure for multiple purposes.
As a significant feature in the Little Rock District, Gentry Lake Dam stands as a testament to the collaboration between private owners and federal agencies in ensuring the safety and sustainability of water resources. While lacking certain regulatory oversight and inspections, this dam showcases the potential for community-driven stewardship in water management. With its historical significance and multifunctional purposes, Gentry Lake Dam continues to be a focal point for water resource and climate enthusiasts in the region.

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.
