Summary
Completed in 2005, this earth dam stands at a height of 18.3 meters and has a hydraulic height of 17.3 meters, providing a storage capacity of 122 acre-feet. With a moderate risk assessment and low hazard potential, the dam is classified as uncontrolled spillway type, ensuring safety and protection for the surrounding area along the UNT of Caney Creek.
Managed by the Mississippi Department of Environmental Quality, Lake Dorothy Dam is subject to state regulation, inspection, and enforcement to ensure its structural integrity and compliance with safety standards. While the dam has not been rated for condition assessment, its risk management measures and emergency action plan readiness contribute to its overall risk mitigation strategy. Situated within the Mobile District of the USACE, the dam serves as a vital resource for water recreation enthusiasts in the region, offering a surface area of 5.3 acres for outdoor activities.
Overall, Lake Dorothy Dam represents a well-maintained and crucial infrastructure for water resource management and climate enthusiasts alike. Its strategic location, low hazard potential, and recreational focus make it a valuable asset for the local community while also highlighting the importance of effective dam management and safety protocols in safeguarding surrounding areas from potential risks and hazards.

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.
