Summary
Built in 1989 by the USDA NRCS, this dam stands at a height of 16.3 feet and has a length of 740 feet, with a storage capacity of 82 acre-feet. The primary purpose of this structure is for Fish and Wildlife Pond, catering to the conservation of natural habitats in the area.
Situated on Cobbs Branch, a river/stream in the Mobile District of Alabama, Marc Mclellan No.3 spans over a surface area of 9 acres, serving as a vital resource for the local ecosystem. With a low hazard potential and a moderate risk assessment rating, this dam plays a crucial role in managing water resources in the region. Although it is not state-regulated, this structure exemplifies the collaboration between private owners and federal agencies in promoting environmental sustainability.
Despite not having a recent condition assessment, Marc Mclellan No.3 remains a key component in the conservation efforts of the area, with a primary focus on fish and wildlife preservation. With its uncontrolled spillway and moderate risk management measures, this dam serves as a beacon of environmental stewardship and underscores the importance of private-public partnerships in safeguarding water resources and mitigating climate risks in Alabama.

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.
