Oh, The Places You'll Flow: The Napa Valley Watershed Features Tour

Water is the lifeblood of our valley. Flowing from mountain forests and hilly chaparral to feed our reservoirs, vineyards, pastures, grasslands and marshes, the Napa River runs 55 miles to San Pablo Bay. Fed by multiple tributaries in the Mayacamas Mountains to the west and Howell Mountain and Atlas Peak to the east, the Napa River watershed is home to 95% of Napa County's population. The dynamic ecosystems contained within our watershed help maintain the health of people, animals, and our economy. Join us on a tour that explores fascinating snapshots of our watershed and learn how we can keep it healthy for generations to come.
