Summary

This earth dam stands at a height of 37 feet and spans 420 feet, providing a storage capacity of 376 acre-feet to control water levels in the TR-Broad Mouth Creek. Despite its fair condition assessment in 2017, this dam has a low hazard potential and is regularly inspected every five years to ensure its safety and functionality.

Managed by the local government, Broadmouth Creek WCD Dam-Minor 4 is regulated by the South Carolina Department of Health and Environmental Control (SC DHEC) and is subject to state permitting, inspection, and enforcement. The dam's spillway, which is controlled, helps manage water flow during high levels, while the uncontrolled outlet gates provide additional control mechanisms. With a normal storage capacity of 56 acre-feet and a surface area of 13 acres, this dam plays a crucial role in protecting the surrounding area from potential flooding events, making it a key asset for water resource and climate enthusiasts to monitor and appreciate.

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.
