Summary
Standing at a height of 30 feet with a length of 3300 feet, this dam provides essential flood protection to the surrounding area. With a storage capacity of 2707 acre-feet and a surface area of 110 acres, the dam plays a crucial role in managing water resources in the region.
The dam's primary purpose also includes creating a fish and wildlife pond, as well as providing recreational opportunities for the community. While the dam is classified as having a significant hazard potential, its condition assessment in 2020 rated it as fair. Regular inspections and maintenance ensure the structural integrity of the dam, with the last inspection conducted in July 2020. Despite being uncontrolled, the spillway width of 10 feet allows for efficient water discharge during heavy rainfall events.
Overall, Bayou Dupont No 8 serves as a vital infrastructure for water resource management and flood control in the region. Its strategic location and design make it a key component in the overall ecosystem, balancing the needs of flood risk reduction, wildlife habitat preservation, and recreational activities for the local community. As climate change continues to impact water resources, structures like Bayou Dupont No 8 play a crucial role in adapting to changing conditions and ensuring the safety and well-being of the surrounding area.

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.
