Lower Weir Lake Dam dam
Lower Weir Lake Dam
Lower Weir Lake Dam, located in East Baton Rouge, Louisiana, is a private dam primarily used for fish and wildlife pond purposes. Constructed in 1985, this earth-type dam stands at 15 feet in height and spans 630 feet in length, with a normal storage capacity of 200 acre-feet. The dam sits on the Amite River and is regulated by the Louisiana Department of Transportation and Development, with state permitting, inspection, and enforcement in place to ensure its safety.
Despite its low hazard potential, Lower Weir Lake Dam has been assessed as being in poor condition as of February 2019. With an inspection frequency of 5 years, the dam poses a moderate risk according to a risk assessment rating of 3. The spillway of the dam is uncontrolled and has a width of 60 feet, allowing for the release of excess water. While the dam does not have a designated emergency action plan prepared, it serves as a vital resource for the surrounding wildlife and recreation in the area.
Enthusiasts of water resources and climate will find Lower Weir Lake Dam to be a fascinating structure that plays a crucial role in supporting local fish and wildlife populations. Its presence on the Amite River, coupled with its regulatory oversight and risk assessment, highlights the importance of maintaining and monitoring dams to ensure the safety of both the environment and surrounding communities.

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 Lower Weir Lake Dam
Where does the data for Lower 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 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.
