Summary

Standing at a height of 11 feet and with a length of 635 feet, the dam helps manage water resources for agricultural purposes in the area. It has a maximum storage capacity of 59.8 acre-feet and a normal storage of 27.4 acre-feet, covering a surface area of 8 acres and serving a drainage area of 0.07 square miles.

The dam, primarily constructed with earth and stone materials, features uncontrolled outlet gates and a low hazard potential. With a focus on irrigation, this structure plays a crucial role in water management and agricultural sustainability in Screven County, Georgia. Despite its importance, the condition assessment of the dam is currently not available, indicating a need for further evaluation and maintenance to ensure its long-term reliability and safety for water resource enthusiasts and climate advocates in the region.

Managed and funded by the Natural Resources Conservation Service, Don Glisson Dam remains a key water infrastructure in the area, showcasing the collaboration between private owners and federal agencies to support water resource management. As the dam continues to play a vital role in irrigation and water storage, efforts to monitor its condition, conduct inspections, and prepare emergency action plans are essential to safeguarding its functionality and resilience in the face of changing climate conditions and growing water resource demands.

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.
