A watershed is a land area that channels rainfall and snowmelt to creeks, streams, and rivers, and eventually to outflow points such as reservoirs, bays, and the ocean. While some watersheds are relatively small, others encompass thousands of square miles and may contain streams, rivers, lakes, reservoirs, and underlying groundwater that are hundreds of miles inland.

- The Community Riparian Restoration Program (CRRP) for Tennessee, a program developed in partnership with the UT Institute of Agriculture and Tennessee Division of Forestry, aims to raise awareness and understanding of riparian buffer systems and their role in our communities through education and applied research. These objectives will be achieved by developing a model and support curriculum to equip Tennessee communities to complete priority forested riparian projects to meet municipal planning, human health, equality, environmental health, recreation, education, and other management objectives.
- Water Quality Forum (Knox County area)—The Water Quality Forum is a coalition of diverse partners including municipalities, utilities, non-profit organizations, and businesses working together to keep our waters in East Tennessee clean.
