Summary
Constructed in 1970 on North White Oak Creek, this earth dam stands at a structural height of 44 feet and has a hydraulic height of 28.2 feet. With a storage capacity of 2140 acre-feet, the reservoir covers a surface area of 66 acres and serves as a vital source of water for the surrounding community.
Maintained by the Tennessee Safe Dams Program, Jamestown Reservoir has a high hazard potential but is currently assessed as satisfactory in condition. The dam, equipped with an uncontrolled spillway, underwent its last inspection in October 2020 and is subject to regular state oversight, including permitting, inspection, and enforcement. Despite its moderate risk assessment, the reservoir plays a crucial role in water management within the region, ensuring a reliable water supply for residents and supporting various activities dependent on its resources.
As climate change continues to impact water resources, the significance of structures like Jamestown Reservoir becomes increasingly apparent. With its regulated status and state jurisdiction, the reservoir stands as a testament to the importance of proactive dam management in mitigating risks and securing water supplies for communities. Climate enthusiasts and water resource advocates alike can appreciate the vital role that Jamestown Reservoir plays in maintaining the water security of Fentress, Tennessee, and the surrounding areas.

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.
