Summary
Built in 1956 across the Loosahatchie River, this earth dam stands at a hydraulic height of 23.5 feet and a structural height of 29.5 feet. It provides a storage capacity of 168 acre-feet, with a normal storage level of 123 acre-feet.
Despite its relatively small size, Beaver poses a high hazard potential due to its location and design. The dam is currently classified as not rated in terms of condition assessment, with a moderate risk level. Even though it is not under federal jurisdiction, the Tennessee Safe Dams Program regulates, permits, inspects, and enforces the operations of Beaver, ensuring its safety and compliance with state regulations.
Water resource and climate enthusiasts may find Beaver an interesting case study in dam management and risk assessment. Its location in a populated area and high hazard potential highlight the importance of ongoing monitoring and maintenance to prevent potential disasters. The moderate risk level and lack of a current condition assessment also underscore the need for continued vigilance and investment in dam infrastructure to ensure the safety and security of surrounding communities.

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.
