Summary
The dam stands at a height of 17 feet with a hydraulic height of 14 feet, and a length of 390 feet. It has a storage capacity of 84 acre-feet, with a normal storage level of 63 acre-feet and a surface area of 11 acres. Despite its low hazard potential and moderate risk assessment rating, the dam's condition assessment remains unrated, with no recent inspection data available.
Situated within the Mobile District of the US Army Corps of Engineers, Dumas Lake Dam features an uncontrolled spillway and outlet gates. The dam has not undergone any recent modifications, and its associated structures are listed as none. While the dam's risk management measures, emergency action plan, and inundation maps status remain unknown, it is essential for water resource and climate enthusiasts to monitor the condition of Dumas Lake Dam due to its location in a region susceptible to extreme weather events and potential impacts on the surrounding area.
As a key recreation feature in the area, Dumas Lake Dam serves as a valuable asset for outdoor enthusiasts. With its picturesque setting and potential for water-based activities, it is crucial for the private owners to prioritize regular inspections and maintenance to ensure the safety and sustainability of the dam for both recreational users and the surrounding environment. Keeping a keen eye on the updates and maintenance of Dumas Lake Dam can help in preserving this important water resource for future generations.

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.
