Summary
Standing at a height of 23 feet and with a length of 369 feet, this earth dam holds a storage capacity of 83 acre-feet of water from the UNT of Goodwater Creek. The dam features an uncontrolled spillway and has a surface area of 8 acres, serving as a popular spot for outdoor enthusiasts in the area.
Managed by the Mississippi Department of Environmental Quality, Carroll Horn Dam is subject to state regulations, inspections, and enforcement to ensure its safety and compliance with environmental standards. While the dam's hazard potential is currently listed as undetermined and its condition assessment is not rated, it falls under a moderate risk category according to the available data. Although the exact year of completion and last inspection date are not provided, the dam continues to offer recreational opportunities and contribute to the local ecosystem in the region.
With its strategic location and essential role in water management for the area, Carroll Horn Dam stands as a vital infrastructure piece in the Vicksburg District. As water resource and climate enthusiasts explore the significance of dams in the region, this earth dam serves as a tangible example of human efforts to harness and utilize natural water resources for recreational and environmental purposes. As its risk management measures are developed and assessed, Carroll Horn Dam remains a focal point for understanding the intersection of water conservation and public safety in Mississippi.

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.
