​The Walnut Creek Watershed Council is a voluntary, non-regulatory stakeholder group that supports a healthy and sustainable
​Walnut Creek Watershed.

We are working to protect and improve over 300 miles of creeks!

​The Walnut Creek Watershed is the largest watershed in Contra Costa County totaling 146 square miles, or 96,000 acres, in size. The Walnut Creek Watershed has 309 miles of creek channels accounting for almost a quarter of all mapped creek channels in Contra Costa County. The watershed extends from San Ramon to the south, Martinez to the north, Moraga and Orinda to the west, and Concord to the east. From protected natural lands (Mt. Diablo State Park, East Bay Regional Park District lands, and Walnut Creek Open Space) and grazed lands to suburbs and urban creeks, our watershed has a bit of almost everything.
