Webster dam
Webster
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.
Dam data reference
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.
- 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.
- 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.
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, environmental 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.

About Webster
Where does the data for Webster come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
