Summary
Shacks Lake, is a captivating earth dam located in Clarke, Alabama, along the Tombigbee River. Owned privately, this dam was designed by the USDA NRCS and completed in 1983 with a primary purpose of serving as a Fish and Wildlife Pond. With a dam height of 16 feet and a length of 480 feet, it has a storage capacity of 123 acre-feet and a normal storage of 55 acre-feet, making it a vital resource for the local ecosystem.
Despite being privately owned, Dunlap-Shackleford Dam has a low hazard potential and a moderate risk assessment rating. With a spillway width of 56 feet and a maximum discharge capacity of 300 cubic feet per second, this dam ensures the safety of the surrounding area while managing water flow efficiently. While its condition is not currently rated, the dam continues to serve as a recreational area for enthusiasts and a vital habitat for fish and wildlife in the region.
Located in Congressional District 07 of Alabama, Dunlap-Shackleford Dam stands as a testament to the importance of water resource management and climate stewardship. With its strategic location along the Tombigbee River, this earth dam plays a crucial role in maintaining ecological balance and providing recreational opportunities for the local community. As a key feature in the landscape of Clarke, Alabama, this dam serves as a reminder of the interconnectedness between water resources, climate, and wildlife conservation.

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.
