Summary

6, located in Harris, Georgia, is a state-owned earth dam designed by the Natural Resources Conservation Service in 1960 for the primary purpose of flood risk reduction along Palmetto Creek. Standing at a height of 38.7 feet and stretching 650 feet in length, this structure has a storage capacity of 596.9 acre-feet and serves a drainage area of 1450 acres. Despite being classified as low hazard potential, it is still subject to regular state inspections to ensure its structural integrity and effectiveness in flood control.

The dam features an uncontrolled spillway and outlet gates, with a normal storage volume of 49.5 acre-feet and a surface area of 11 acres. Although not currently rated for condition assessment, its risk potential is considered moderate. The last inspection in February 2020 reaffirmed its operational status, with a 5-year inspection frequency in place to monitor any changes in its performance. With the dam's strategic location in Pine Mountain Valley and its vital role in mitigating flood risks, water resource and climate enthusiasts can appreciate the significance of Palmetto Creek Watershed Structure No. 6 in safeguarding the local community from potential water-related disasters.

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.
