Summary
2 is a privately owned Earth dam located in Demopolis, Alabama, along the TR-Big Prairie river. Built in 1987 by the USDA NRCS, this dam serves as a Fish and Wildlife Pond, providing valuable habitat for various species in the area. With a height of 14 feet and a length of 1155 feet, Harry Horn No. 2 has a storage capacity of 207.9 acre-feet and a surface area of 23 acres, making it a significant resource for water management and conservation.
Despite its low hazard potential and moderate risk assessment, Harry Horn No. 2 has not been rated for its condition and has not undergone recent inspections. The dam features an uncontrolled spillway with a width of 60 feet, capable of discharging up to 840 cubic feet per second. While not regulated by the state and lacking in emergency action preparedness, this dam remains a vital component of the local ecosystem and water resource infrastructure. Enthusiasts of water resources and climate will find Harry Horn No. 2 to be a fascinating example of human-made structures contributing to environmental sustainability and wildlife conservation in Alabama.

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.
