Summary
Constructed in 1971 by the USDA NRCS, the dam serves the primary purpose of creating a fish and wildlife pond, as well as providing recreational opportunities for local residents and visitors. With a dam height of 18 feet and a length of 425 feet, the structure has a storage capacity of 504 acre-feet and a drainage area of 1.54 square miles.
Situated on the TR-Tombigbee River in the Mobile District, Dunlap Dam has an uncontrolled spillway with a width of 80 feet and a maximum discharge capacity of 824 cubic feet per second. Despite being classified as having a low hazard potential, the dam's risk assessment is moderate, with a readiness level of 3. The condition assessment for the structure is currently listed as not rated, with no inspection frequency specified. While the dam meets guidelines for emergency action planning, details such as the last revision date and inundation maps are not available at this time.
For water resource and climate enthusiasts, Dunlap Dam presents an interesting case study in private dam ownership and management. With its focus on enhancing fish and wildlife habitats and supporting recreational activities, the structure serves as a valuable asset for the local community. As efforts continue to assess and mitigate potential risks associated with the dam, ongoing monitoring and maintenance will be essential to ensure the safety and sustainability of Dunlap Dam for years to come.

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.
