Summary
This private earth dam stands at a height of 30 feet and stretches 1232 feet in length, with a storage capacity of 751 acre-feet and a drainage area of 1.3 square miles. The dam's spillway, which is uncontrolled and 11 feet wide, helps manage a maximum discharge of 1160 cubic feet per second.
Despite being in fair condition as of the last assessment in July 2020, Bayou Dupont No 20 poses a significant hazard potential, prompting a moderate risk assessment rating. The dam is regulated by the Louisiana Department of Transportation and Development, which conducts inspections every three years to ensure its structural integrity and safety. With its primary purpose being flood risk reduction, this water infrastructure also serves as a fish and wildlife pond, as well as a recreational area for locals and visitors to enjoy. As climate change continues to impact water resources, monitoring and maintaining structures like Bayou Dupont No 20 are crucial for sustainable water management 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.
