Summary

Situated in the Altamont Community, the dam spans across Stacy Creek TRIB and is part of the Nashville District. With a hydraulic height of 9.6 feet and a structural height of 12.6 feet, the dam holds a normal storage capacity of 3 acre-feet and a maximum storage of 7 acre-feet.

Although the dam was last inspected in April 2011 and deemed to be in satisfactory condition, it is classified as having a significant hazard potential. Despite not being state-regulated or permitted, the Calloway Dam plays a vital role in providing recreational opportunities for water resource and climate enthusiasts in the area. As an Earth-type structure, the dam serves as a popular spot for outdoor activities and scenic views, attracting visitors from across the region.

As climate change continues to impact water resources and the environment, understanding and monitoring dams like Calloway Dam becomes increasingly important. With its unique location and features, the dam serves as a reminder of the delicate balance between human recreation and natural ecosystems, making it a significant site for both leisure and conservation efforts.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
