Summary
Built in 1989 by the USDA NRCS, this earth dam stands at a height of 14 feet and has a length of 816 feet, providing a storage capacity of 82 acre-feet. The primary purpose of this structure is to support fish and wildlife habitats, with a low hazard potential and moderate risk assessment.
Situated on Cobb's Branch, a tributary in the Mobile District, Marc Mclellan No.2 covers an area of 10.5 acres and has a drainage area of 0.14 square miles. The spillway, which is uncontrolled, has a width of 35 feet and can handle a maximum discharge of 275 cubic feet per second. Despite its age, the dam's condition is currently listed as "Not Rated", with no recent inspections reported since 1989.
For water resource and climate enthusiasts, Marc Mclellan No.2 offers a fascinating case study of a privately-owned structure designed to enhance local ecosystems. With its unique design and purpose, this dam showcases the intersection of conservation efforts and water management in rural Alabama. As discussions around sustainable water practices continue, the role of structures like Marc Mclellan No.2 in supporting biodiversity and environmental resilience becomes increasingly relevant.

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.
