SDCWC began as a sub-basin planning team within the Mid-Coast Watershed Council in the late 1990s. In 2003, it became clear to those active on Salmon River and Drift Creek watershed education and restoration efforts that the Salmon and Drift watersheds were sufficiently separate and that there was enough volunteer energy and agency support for the SDCWC to begin work to establish an independent watershed council.
In 2005, the SDCWC was organized as a 501(c)(3) non-profit public corporation with a board of directors and by-laws. Since then, the SDCWC has received grants and donations from a variety of public and private sources for public education and watershed restoration.
Working with a variety of city, county, state, and federal agencies, and private landowners, SDCWC has completed many monitoring and restoration projects in the watersheds that lie within its jurisdiction. SDCWC's jurisdiction extends from the Salmon River to Drift Creek.
SDCWC and its partners have received numerous awards for work on these projects.
