Summary
This private earth dam stands at a height of 10 feet and has a length of 610 feet, with a storage capacity of 135 acre-feet. The dam overlooks the TR-LONG BRANCH river/stream and is owned and regulated by the South Carolina Department of Health and Environmental Control (SC DHEC).
Despite its low hazard potential, the dam's condition has been assessed as poor as of November 2017. With a moderate risk rating, it is subjected to inspections every five years to ensure public safety. The dam lacks necessary emergency action plans and inundation maps, highlighting the need for improved risk management measures in case of any unforeseen events. The dam's spilway is uncontrolled, and it has no outlet gates or associated structures.
For water resource and climate enthusiasts, Blake Plant Pond Dam 1 serves as an example of a recreational dam in need of attention and maintenance to mitigate potential risks. Its historical significance and role in water storage make it a focal point for discussions on dam safety and regulatory oversight. As efforts to improve its condition and emergency preparedness continue, the dam remains a crucial asset in the region's water management infrastructure.

Dam Data Reference
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.
