About this dam

Bayou Dupont No 7

Bayou Dupont No 7, also known as Broadway Pond, is a private water resource located in Sabine, Louisiana, managed by the USDA NRCS. This earth dam, completed in 1961, serves multiple purposes including flood risk reduction, fish and wildlife conservation, and recreation. The dam stands at 36 feet in height, with a storage capacity of 504 acre-feet and a surface area of 23 acres.

Managed by the Louisiana Department of Transportation and Development, Bayou Dupont No 7 has a significant hazard potential and a fair condition assessment as of July 2020. The dam's spillway is uncontrolled with a width of 11 feet, and it has a drainage area of 2.57 square miles with a maximum discharge of 1345 cubic feet per second. With its location in the Fort Worth District, the dam is a vital structure for flood risk management in the region.

Water resource and climate enthusiasts will appreciate the role of Bayou Dupont No 7 in mitigating flood risks in the area while providing opportunities for recreational activities and wildlife conservation. The dam's design by the USDA NRCS and its state-regulated status ensure proper maintenance and inspection to uphold its function effectively. As part of the broader water management system in Louisiana, Bayou Dupont No 7 plays a crucial role in safeguarding the surrounding community and environment from potential flooding events.

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.

FAQ

About Bayou Dupont No 7

Where does the data for Bayou Dupont No 7 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.
