Summary

Constructed in 1993 by the USDA NRCS, this earth dam spans 298 feet in length and reaches a height of 27 feet, providing a storage capacity of 34 acre-feet. The primary purpose of the dam is to create a Fish and Wildlife Pond, showcasing its commitment to environmental stewardship and habitat preservation along the TR- Savannah River.

Managed by a private entity, Marvin Mckie Dam is subject to state regulations and inspections by the South Carolina Department of Health and Environmental Control. With a low hazard potential and fair condition assessment, the dam ensures public safety while contributing to the local ecosystem. Despite its uncontrolled spillway and outlet gates, the dam's risk assessment remains moderate, emphasizing the need for ongoing monitoring and potential risk management measures in the future.

As a vital component of water resource management in the region, Marvin Mckie Dam serves as a testament to the collaborative efforts between private owners and government agencies in balancing the needs of wildlife conservation and recreational use. With its strategic location along the TR- Savannah River and its significant impact on the surrounding landscape, this dam exemplifies the intersection of human ingenuity and environmental sustainability in the face of climate change challenges.

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.
