Summary
Built in 1966, this privately owned Earth dam serves the primary purpose of recreation, with additional benefits for water supply. The dam has a hydraulic height of 12 feet and a structural height of 13 feet, providing a storage capacity of 125 acre-feet and a normal storage level of 114 acre-feet.
Situated on the TR-POWCREEK OFFSTREAM, Bethea offers a tranquil setting for outdoor enthusiasts to enjoy water activities and wildlife observation. The dam has a low hazard potential and is currently not rated for its condition assessment. While it is not regulated by the state and does not have a designated emergency action plan, Bethea remains an important part of the local ecosystem and a popular recreational spot for the community.
Despite its modest dimensions, Bethea plays a crucial role in providing recreational opportunities and supporting water supply in the area. With its picturesque surroundings and peaceful atmosphere, this dam serves as a valuable asset for residents and visitors alike, highlighting the importance of sustainable water resource management and climate-conscious recreational development in the region.

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.
