Summary

Built in 1965 for recreational purposes, this earth dam stands at a structural height of 35 feet and has a hydraulic height of 31.2 feet. With a storage capacity of 338 acre-feet and a drainage area of 0.43 square miles, Shoaf plays a crucial role in managing water flow in the Tribskillern Creek.

Despite its age, Shoaf has been regularly inspected and deemed to be in satisfactory condition as of the last assessment in March 2019. The dam poses a significant hazard potential, but risk assessment indicates a moderate level of risk. While currently uncontrolled, the spillway type suggests some level of safety measures in place. The Tennessee Safe Dams Program oversees the state regulation, permitting, inspection, and enforcement of the dam, ensuring its continued safety and functionality.

As an important structure in the region, Shoaf serves as a reminder of the intersection between water resources and climate resilience. Its maintenance and management are crucial for both water supply and recreational activities in the area. With proper oversight and continued assessments, Shoaf will remain a valuable asset for the community and a testament to responsible water resource management practices.

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.
