Summary
Montgomery III No.1 is a private-owned earth dam located in Demopolis, Alabama, designed by the USDA NRCS and completed in 1987. Its primary purpose is to serve as a Fish and Wildlife Pond, with a storage capacity of 75 acre-feet and a surface area of 8.2 acres. The dam stands at 15 feet in height and spans 900 feet in length, creating a habitat for aquatic life and supporting recreational activities in the area.
Situated on the TR-Wilkes Creek in Greene County, Alabama, J.H. Montgomery III No.1 has a low hazard potential and a moderate risk assessment rating. With a maximum discharge capacity of 310 cubic feet per second and an uncontrolled spillway width of 40 feet, the dam's design ensures effective water management and flood control. While the dam's condition assessment is currently listed as "Not Rated," its construction and purpose highlight its significance in supporting local ecosystems and enhancing water resources in the region.
Overall, J.H. Montgomery III No.1 serves as a vital infrastructure for promoting biodiversity and wildlife conservation in Alabama. Its strategic location and design play a crucial role in maintaining water quality, supporting fish and wildlife habitats, and providing recreational opportunities for the community. As a testament to the collaboration between private ownership and federal agencies like the USDA NRCS, this dam symbolizes the importance of sustainable water resource management and climate resilience efforts in the face of environmental challenges.

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.
