Webster is a privately-owned dam located in Roane, Tennessee, along Post Oak Creek. 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.
