Bo Chevallier Dam dam
Bo Chevallier Dam
Bo Chevallier Dam, located in Many, Louisiana, is a privately owned structure that was completed in 1991 for the primary purpose of recreation. This earth dam, designed by USDA NRCS, stands at a height of 20 feet with a hydraulic height of 16 feet and a structural height of 23 feet. The dam spans 590 feet in length and has a storage capacity of 156 acre-feet, with a normal storage level of 125 acre-feet.
The dam, situated on the SAN JOSE CREEK in Sabine County, Louisiana, is regulated by the Louisiana Department of Transportation and Development. With a spillway width of 110 feet and a maximum discharge capacity of 2922 cubic feet per second, the dam has been assessed to have a low hazard potential and fair condition as of the last inspection in July 2019. Despite its moderate risk rating, the dam has not been assigned a Dam Safety Action Classification (DSAC) date, indicating a need for ongoing monitoring and risk assessment.
For water resource and climate enthusiasts, the Bo Chevallier Dam serves as an important recreational structure in the region, providing opportunities for outdoor activities and water-based recreation. The dam's construction and maintenance are overseen by private entities, with a focus on ensuring public safety and proper regulation by state agencies. As climate change continues to impact water resources, monitoring and assessing the condition of dams like Bo Chevallier become increasingly crucial for sustainable water management and climate resilience in the future.

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 Bo Chevallier Dam
Where does the data for Bo Chevallier Dam 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.
