Summary
Completed in 1991, this Earth-type dam stands at 25 feet in height and spans 1000 feet in length. With a normal storage capacity of 350 acre-feet and a maximum storage of 738 acre-feet, the dam serves as a vital resource for water management in the area.
Managed by the Mississippi Department of Environmental Quality, Harrel Dam is regulated, inspected, and enforced by the state to ensure its safe operation. The dam's spillway, classified as uncontrolled, has a maximum discharge capacity of 1500 cubic feet per second. Despite being labeled as having an undetermined hazard potential and a moderate risk assessment, the dam's condition remains unrated, and emergency preparedness measures are not specified.
Water resource and climate enthusiasts will find Harrel Dam to be a fascinating structure that not only provides recreational opportunities but also plays a crucial role in water storage and management in the region. With its history of construction and its current state of operation, this dam serves as a key component in the overall water infrastructure of the area, highlighting the importance of sustainable water resource management in the face of changing climate conditions.

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.
