Canning Lake Dam Wwtp dam
Canning Lake Dam Wwtp
Canning Lake Dam Wwtp, located in Avoyelles, Louisiana, is a privately owned structure regulated by the Louisiana Department of Transportation and Development. Built in 1970 by designer J D Mayeau, this Earth dam stands at 7 feet high with a hydraulic height of 6 feet and a length of 4530 feet. The dam serves a primary purpose other than flood control, with a normal storage capacity of 216 acre-feet and a maximum storage of 252 acre-feet.
Despite its low hazard potential and fair condition assessment, Canning Lake Dam Wwtp poses a high risk due to its location near the TR-Bayou Des Allemands. The dam lacks a spillway and outlet gates, with no associated locks for navigation. Its last inspection was conducted in October 2012, with a scheduled inspection frequency of 5 years. While the dam meets state permitting, inspection, and enforcement requirements, there are no emergency action plans or risk management measures in place.
For water resource and climate enthusiasts, Canning Lake Dam Wwtp provides an intriguing case study of a privately owned Earth dam in Louisiana. With its unique design features and potential risks, this structure offers opportunities for further research and analysis in the realm of dam safety and water resource management. The presence of a high-risk assessment despite a low hazard potential highlights the complexities of balancing infrastructure needs with environmental considerations in a changing climate.

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 Canning Lake Dam Wwtp
Where does the data for Canning Lake Dam Wwtp 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.
