Summary
Built in 1961, this earth dam stands at a structural height of 40 feet and has a storage capacity of 32 acre-feet. With a primary purpose of recreation, the dam also serves for fire protection, stock, and small fish pond activities. Its low hazard potential and moderate risk assessment make it a relatively stable structure within the Nashville District.
Although not state-regulated, Webster has undergone inspections every five years, with the last one recorded in January 2019. The dam's condition is currently not rated, and no emergency action plan (EAP) has been prepared. Despite its uncontrolled spillway type, Webster poses a low risk of failure. Its location in a scenic area with a surface area of 1.8 acres makes it an ideal spot for recreational activities. While the dam's primary source agency is the state of Tennessee, it does not fall under state jurisdiction for regulation, permitting, inspection, or enforcement.
For water resource and climate enthusiasts, Webster serves as an intriguing case study of a privately-owned dam with multiple purposes beyond recreation. Its design and construction in the early 1960s reflect the era's approach to water management for various uses. As an unregulated structure with a low hazard potential, it offers insights into risk assessment and management practices for similar dams in the region. The dam's association with Post Oak Creek highlights the importance of sustainable water resource management in the face of changing climate patterns.

Dam Data Reference
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.
