Summary

Bayou Na Banchasse, stands as a testament to the ingenuity and vision of the Father of Scott Gentry, serving as a private recreational haven since its completion in 1964. With a primary purpose of recreation, this Earth dam with a buttress core and soil foundation boasts a height of 9 feet and a length of 672 feet, providing a serene surface area of 18 acres for visitors to enjoy.

Owned privately and regulated by the Louisiana Department of Transportation and Development, Scott Gentry Dam offers a low hazard potential with a fair condition assessment. Despite its moderate risk rating, the dam has undergone inspections every five years, with the most recent assessment conducted in September 2015. With its uncontrolled spillway and maximum storage capacity of 108 acre-feet, this dam not only enhances the natural landscape but also serves as a vital part of the local water resource infrastructure.

As enthusiasts of water resources and climate, the Scott Gentry Dam presents a unique blend of recreational opportunities and environmental stewardship. Nestled in the scenic countryside of Holly, Louisiana, this dam provides a tranquil escape for visitors while ensuring the safety and sustainability of the surrounding ecosystem. With its rich history, modest risk profile, and commitment to regular inspections, Scott Gentry Dam is a shining example of how human innovation can harmonize with nature to create a lasting impact on the community.

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.
