Summary

This earth dam, primarily used for recreation purposes, has a normal storage capacity of 156 acre-feet and a maximum storage capacity of 201.9 acre-feet. The dam spans 655 feet in length and has a surface area of 12 acres, providing a picturesque setting for water resource and climate enthusiasts to explore.

Managed by a private owner, Lake Milt-Ann Dam is situated on Gin Creek and falls under the jurisdiction of the state of Georgia. The dam's hazard potential is rated as low, with a moderate risk assessment rating of 3. While the condition assessment is not rated, the dam is inspected every five years to ensure its structural integrity and safety. With its uncontrolled spillway and outlet gates, Lake Milt-Ann Dam offers a tranquil environment for outdoor activities and serves as a vital resource for the surrounding community.

Despite its low hazard potential, Lake Milt-Ann Dam remains a key recreational attraction in the Shiloh Environs area, drawing visitors to its serene waters and scenic surroundings. The dam's historical significance, coupled with its functional design by SCS (Hollis Billings), underscores its importance as a valuable water resource and climate asset in Harris County, Georgia. Whether for leisurely boating, fishing, or simply enjoying nature, Lake Milt-Ann Dam provides a peaceful retreat for enthusiasts seeking to connect with the beauty of the great outdoors.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
