Summary
Situated on Eight Mile Creek, this earth dam stands at a height of 10 feet with a length of 750 feet, providing a storage capacity of 116 acre-feet. With a normal storage level of 92 acre-feet and a surface area of 32 acres, Manning Dam plays a crucial role in irrigation and recreation activities in the region.
Managed by the Mobile District of the US Army Corps of Engineers, Manning Dam has a low hazard potential and has not been rated for its current condition. Although the last inspection was conducted in May 1994, the dam remains in compliance with state regulations for inspection, permitting, and enforcement. While the dam has not undergone any modifications in recent years, it continues to serve its intended purposes effectively, showcasing the importance of water resource management and climate resilience in the area.
Despite its age, Manning Dam stands as a testament to the engineering expertise of its time, with its structure designed to withstand the challenges posed by the surrounding environment. As a key component in the water infrastructure of Walton County, Florida, Manning Dam remains a valuable resource for the community, highlighting the vital role that sustainable water management practices play in ensuring the long-term resilience of our water resources in the face of a changing climate.

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.
