Flood Damage Reduction
When TVA was founded in 1933, flooding was a serious problem in the Tennessee Valley.
Untamed rivers washed away the topsoil, causing severe erosion and limiting farmers’ ability to grow crops; poor farming practices compounded the problem. The potential for flood damage increased as cities and towns were built alongside the rivers. Property was regularly devastated. In many cases, lives were lost.
From the beginning, TVA was charged with coming up with solutions for these problems, and taming the wild waters that were taking such a heavy toll on the land.
Today, TVA has a sophisticated system of dams to control flooding along the Tennessee River watershed, and each year it prevents about $240 million in flood damage in the TVA region and along the Ohio and Mississippi Rivers. To date, the operation of this system has prevented over $5.4 billion in flood losses across the Tennessee Valley, including about $4.9 billion in damage averted at Chattanooga—the Valley’s most flood-prone city. (The system has also prevented about $470 million in flood losses in the lower Ohio and Mississippi River drainage basins.)
