Summary
Completed in 1971, this earth dam stands at a height of 33 feet and spans 650 feet in length. It holds a maximum storage capacity of 167 acre-feet, with a normal storage level of 124 acre-feet. The dam is situated on Mill Creek and is under the jurisdiction of the Mississippi Department of Environmental Quality.
Despite its primary purpose of recreation, Brinkley Lake Dam poses a high hazard potential with an unsatisfactory condition assessment as of September 2019. The dam's spillway, categorized as uncontrolled, has a maximum discharge capacity of 1200 cubic feet per second. In the face of these risks, the dam undergoes inspections every five years to ensure its structural integrity and safety. The dam is owned privately and is not associated with any federal agencies.
As water resource and climate enthusiasts, it is crucial to monitor the condition and management of dams like Brinkley Lake Dam to prevent potential hazards and ensure the safety of surrounding communities. With its scenic location and significant storage capacity, Brinkley Lake Dam remains a valuable asset for recreation in the region while also requiring diligent oversight to mitigate any risks associated with its operation.

Dam Data Reference
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.
