Nashville (AP) -- The Tennessee Transportation and Environment departments are working together to post watershed signs along highways.
The signs are intended to increase awareness of the value of Tennessee's rivers, streams, wetlands, lakes and groundwater.
A watershed is the entire land area that drains into a stream or lake.
Transportation Commissioner Gerald Nicely says officials hope to inspire people to keep the areas free of pollution.
Environment and Conservation Commissioner Jim Fyke says protecting water resources is a bigger job than government can do alone and requires the help of all citizens.
The signage program will begin with placement of 187 signs along interstate highways and state routes.
Each watershed may have between two and ten signs, depending on how many major highways enter it.
