Impounding Basin No 2 dam
Impounding Basin No 2
Impounding Basin No 2, also known as S.B. 2 and 3, is a privately owned water supply structure located in Sarepta, Louisiana along the Bodcau River. Built in 1938 by International Paper, this earth dam stands at a height of 25 feet with a hydraulic height of 23 feet and a structural height of 25 feet. With a capacity of 3956 acre-feet, the basin covers a surface area of 516 acres and serves as a vital water resource for the region.
Despite its historical significance, Impounding Basin No 2 is currently rated as having a poor condition assessment and a very high risk level (1). The dam's last inspection in November 2020 revealed maintenance issues, prompting concerns about its structural integrity. The Louisiana Department of Transportation and Development regulates the site and conducts regular inspections, emphasizing the importance of ongoing monitoring and risk management measures to ensure public safety and the preservation of this essential water supply infrastructure.
As water resource and climate enthusiasts, it is crucial to recognize the significance of structures like Impounding Basin No 2 in maintaining the stability of our water supply systems. By staying informed about the condition of such dams and advocating for necessary repairs and upgrades, we can contribute to the sustainable management of our water resources and mitigate potential risks associated with aging infrastructure. Let us work together to protect and preserve vital assets like Impounding Basin No 2 for future generations.

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 Impounding Basin No 2
Where does the data for Impounding Basin No 2 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 Low 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.
