Bayou Dupont No 8 dam
Bayou Dupont No 8
Bayou Dupont No 8, located in Natchitoches, Louisiana, is a privately owned earth dam constructed in 1959 by the USDA NRCS for flood risk reduction along Brushy Creek. 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.

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.
- 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.
- 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.
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, environmental 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.

About Bayou Dupont No 8
Where does the data for Bayou Dupont No 8 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
