The Harpeth River Watershed is located in Middle Tennessee and includes parts of Cheatham, Davidson, Dickson, Hickman, Rutherford, and Williamson Counties. The Harpeth River Watershed is approximately 863 square miles and drains to the Cumberland River.
TDEC is currently working through a stakeholder-driven process to study the Harpeth River watershed, explore the data available, and determine the best path forward.
The purpose of this page is to keep all interested parties informed about activities that are going on throughout this development process.
