Summary
This dam plays a crucial role in managing water resources in the region, with a normal storage capacity of 138 acre-feet and a surface area of 5.8 acres. While the dam's primary purpose and design details are not specified, its importance in regulating water flow and storage cannot be understated.
Despite its importance, the dam's hazard potential is listed as 'Undetermined,' and its condition assessment is marked as 'Not Rated.' This suggests that there may be uncertainties regarding the safety and structural integrity of the dam, raising concerns for potential risks and the need for further evaluation and monitoring. The lack of recent inspection data and assessment updates also indicate a need for enhanced oversight and maintenance to ensure the dam's continued functionality and safety for the surrounding communities.
As water resource and climate enthusiasts, the John D Montgomery Dam presents an intriguing case study in the intersection of infrastructure management, environmental protection, and community safety. Its location within the Nashville, Savannah, and Wilmington Districts highlights its regional importance, while the unresolved issues surrounding its hazard potential and condition assessment underscore the complexities and challenges of maintaining critical water infrastructure. Continued attention and investment in monitoring, maintenance, and risk mitigation efforts will be essential to safeguarding the dam's long-term functionality and resilience in the face of changing climate conditions and water resource demands.

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.
