Summary
Built in 1958 by the USDA NRCS, this dam serves multiple purposes including flood risk reduction, fish and wildlife pond creation, and recreational opportunities. With a height of 26 feet and a length of 1687 feet, it has a storage capacity of 1735 acre-feet and covers a surface area of 98 acres.
Managed by the Louisiana DOTD, Bayou Dupont No 10 is regulated, inspected, and enforced by state authorities to ensure its structural integrity and functionality. The dam has an uncontrolled spillway with a width of 10 feet, and a significant hazard potential has been identified, although its condition assessment is currently rated as fair. Despite being in operation for over six decades, the dam continues to play a crucial role in managing water resources in the region and mitigating flood risks along Bayou Pedro.
With a moderate risk assessment rating, Bayou Dupont No 10 remains a key piece of infrastructure for the surrounding area, providing both environmental and recreational benefits to the community. As water resource and climate enthusiasts, tracking the ongoing maintenance and management of this dam can offer valuable insights into sustainable water management practices and the importance of infrastructure resilience in the face of changing climate conditions.

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.
