A watershed is an area of land where all of the rainwater that falls on it drains to the same place. Lexington has seven urban and two rural watersheds.
Watershed monitoring in West Hickman
Watershed monitoring is an important tool to improve Lexington's water quality. Currently, Lexington is performing water quality tests at different stream locations to help determine what pollutants to focus on to improve water quality. This is a multi-year project that will go from watershed to watershed.
