Summary

This earth dam stands at 36 feet high and has a length of 600 feet, with a storage capacity of 80 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2017 was rated as poor, indicating a need for maintenance and potential upgrades to ensure its continued safety and functionality.

Managed by the South Carolina Department of Health and Environmental Control, J E Mcdaniel Dam 1 is regulated, permitted, inspected, and enforced by state authorities. The dam's primary source agency is the state of South Carolina, with no federal funding or agency involvement in its operations. The risk assessment for the dam is moderate, highlighting the need for proactive risk management measures and potentially the development of an Emergency Action Plan to ensure the safety of downstream communities in case of a dam failure.

Surrounded by the picturesque landscape of the TR-HORN CREEK, J E Mcdaniel Dam 1 serves not only as an essential water resource for irrigation but also offers recreational opportunities. With a modest surface area of 7 acres and uncontrolled spillway and outlet gates, the dam presents both challenges and opportunities for enhancing its functionality and safety. Climate and water resource enthusiasts may find J E Mcdaniel Dam 1 a fascinating case study in the intersection of infrastructure, environmental stewardship, and risk management in the context of changing climate conditions.

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.
