Prattville Lake dam
Prattville Lake
Prattville Lake, located in Autauga, Alabama, is a man-made reservoir built in 1920 primarily for recreational purposes. The dam, with a hydraulic height of 27 feet and a length of 310 feet, serves as a significant water resource for the surrounding community. The lake has a normal storage capacity of 86 acre-feet and a maximum discharge of 5400 cubic feet per second, making it an essential resource for water enthusiasts and climate advocates in the area.
Despite not being regulated by the state, Prattville Lake has been deemed to have a significant hazard potential. The condition of the dam is currently not rated, with no recent inspection or assessment data available. The emergency action plan (EAP) status and risk assessment for the lake are also unknown, raising concerns about the preparedness and management measures in place for potential emergencies. The lack of information on the dam's maintenance and safety procedures highlights the need for increased monitoring and oversight to ensure the protection of the lake and surrounding areas.
As a vital water resource in the region, Prattville Lake's condition and safety are crucial for both recreational activities and environmental sustainability. With its historical significance and potential risks, there is a growing need for updated inspections, risk assessments, and emergency action plans to safeguard this valuable resource for future generations. Water resource and climate enthusiasts should advocate for increased monitoring and maintenance efforts to ensure the continued health and safety of Prattville Lake.

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 Prattville Lake
Where does the data for Prattville Lake 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.
