Bayou Dupont No 11 dam
Bayou Dupont No 11
Bayou Dupont No 11, also known as Nichols Pond, is a private-owned structure located in Sabine, Louisiana, specifically in the city of Robeline Village. Built in 1959 by the USDA NRCS, this earth dam stands at a height of 31 feet and serves multiple purposes including flood risk reduction, fish and wildlife habitat, and recreation. With a storage capacity of 1046 acre-feet and a drainage area of 1.6 square miles, Bayou Dupont No 11 plays a vital role in managing water resources in the region.
The dam, situated on Bayou Pedro, has a spillway width of 10 feet and a maximum discharge capacity of 1355 cubic feet per second, making it a significant structure with a fair condition assessment. It is regulated and inspected by the Louisiana Department of Transportation and Development, ensuring its safety and integrity. The hazard potential is classified as significant, with a moderate risk level, which indicates the importance of ongoing management and maintenance efforts to mitigate potential risks.
Overall, Bayou Dupont No 11 is a crucial asset for flood risk reduction and water management in the area, highlighting the importance of sustainable infrastructure development in the face of changing climate conditions. Its role in providing essential services while also supporting wildlife and recreational activities underscores the interconnected relationship between water resources and climate resilience in Louisiana.

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 11
Where does the data for Bayou Dupont No 11 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.
