“It is within the systems of the watershed that a farmer learns how to grow winegrapes in a way that degrades neither the land nor the people. The most important concept to understand about sustainable agriculture is that farming takes place in an area much greater than legal property lines—winegrowers farm in a watershed”
—Vineyards in the Watershed, 2002.

RCDs work collaboratively with grapegrowers to achieve management goals and conserve local agricultural and natural resources.
