Sanders Pond Dam, also known as Robert Connelly Dam 1, is a private-owned structure located in Allendale, South Carolina.
Summary
Completed in 1925, this Earth-type dam stands at 8 feet tall and stretches 925 feet in length, creating a reservoir with a normal storage capacity of 104 acre-feet and a maximum storage of 178.2 acre-feet. The primary purpose of Sanders Pond Dam is for recreation, providing a serene setting for water activities in the surrounding area.
Managed by the South Carolina Department of Health and Environmental Control (DHEC), Sanders Pond Dam is state-regulated and undergoes regular inspections with a low hazard potential. Although its condition assessment is currently marked as "Not Rated," the dam remains structurally sound for its recreational function. The inspection frequency is set at 5 years, with the last assessment conducted in August 2017. Despite its age, Sanders Pond Dam continues to offer a safe and enjoyable environment for water resource and climate enthusiasts to appreciate and explore.
Situated along Duck Branch in the Savannah District, Sanders Pond Dam is a historic landmark that adds to the natural beauty of the region. With its modest surface area of 37 acres, this dam provides a tranquil escape for visitors seeking outdoor recreation opportunities. As a vital part of the local landscape, Sanders Pond Dam exemplifies the importance of responsible dam management and conservation practices in sustaining water resources for future generations to enjoy.

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.
