Summary
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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
