Brilliant Lake Dam Reservoir Report
Last Updated: December 5, 2025
Brilliant Lake Dam is a privately owned structure located in Marion, Alabama, with a significant hazard potential due to its condition being "Not Rated." Although the dam is primarily used for purposes other than water resource management, its exact specifications such as height, volume, and storage capacity are not provided in the data.

Summary
The dam is classified as an Earth type dam, suggesting it is built from earth materials and may not have a concrete or steel structure.
The dam is under the jurisdiction of the state of Alabama and is not regulated by any state agency. It is situated within the Mobile District of the US Army Corps of Engineers, but it is not owned, funded, designed, constructed, or regulated by any federal agency. With no recent inspection or assessment data available, the condition and safety of Brilliant Lake Dam remain uncertain, highlighting the need for further evaluation and potential risk management measures to ensure the safety of the surrounding community and environment. Water resource and climate enthusiasts may find this structure intriguing due to its unique ownership, lack of state regulation, and significant hazard potential.

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.
