Summary
The primary purpose of this dam is flood risk reduction along the TR-Bayou Dupont, with a hydraulic height of 20 feet and a structural height of 23 feet. It has a maximum storage capacity of 265 acre-feet and a normal storage capacity of 230 acre-feet, serving to protect the surrounding area from potential flooding events.
This low hazard potential dam spans 1650 feet in length and features an uncontrolled spillway with a width of 135 feet. While it has not been rated for condition assessment since a 2010 inspection, it is regulated, inspected, and enforced by the Louisiana Department of Transportation and Development. With a moderate risk assessment of (3), this dam plays a crucial role in managing the water resources in the region and protecting against the impacts of climate change on flooding events.
Overall, Bayou Dupont No 13 serves as an important infrastructure for flood risk reduction in the Fort Worth District, providing a buffer against potential inundation in the area. Its strategic location and design by the USDA NRCS underscore its significance in water resource management, highlighting the collaborative efforts between private owners and state regulatory agencies to safeguard against natural disasters. For enthusiasts of water resources and climate resilience, this dam represents a key component in the broader network of infrastructure aimed at mitigating the impact of extreme weather events on local communities.

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.
