Upper Weir Lake Dam dam
Upper Weir Lake Dam
Upper Weir Lake Dam, located in East Baton Rouge, Louisiana, is a privately owned structure that serves as a fish and wildlife pond for recreational purposes. Completed in 1985, this earth dam stands at a height of 10 feet with a hydraulic height of 6 feet, providing a normal storage capacity of 120 acre-feet. The dam spans 260 feet in length and has a spillway width of 45 feet, making it a significant contributor to the local water resource management system.
Managed by the Louisiana Department of Transportation and Development, Upper Weir Lake Dam has been deemed to have a fair condition assessment as of the last inspection in February 2019. With a hazard potential rated as significant and a moderate risk level, the dam presents challenges that require diligent monitoring and risk management measures. Despite its relatively small size, the dam plays a crucial role in maintaining the ecological balance of the area and providing a source of recreation for the community.
As a vital component of the Tr-Amite River watershed, Upper Weir Lake Dam serves as a reminder of the importance of sustainable water resource management in the face of changing climate patterns. With its strategic location and function, the dam stands as a beacon for water and climate enthusiasts, showcasing the delicate balance between human development and environmental conservation in the ever-evolving landscape of Louisiana's water infrastructure.

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 Upper Weir Lake Dam
Where does the data for Upper Weir Lake 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 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.
