Our Mission: The Mill Valley StreamKeepers is a community action group working to restore and protect Mill Valley’s Watersheds.

Our organization seeks to protect the ecological health, and the well-being of Mill Valley’s wildlife inhabitants while working to keep our watersheds and streams healthy and as natural as possible for the enjoyment of current and future residents. The organization was formed by community volunteers in March, 1998, to continue the efforts of the Mill Valley Watershed Project, which began in 1994. We focus on protecting and restoring Mill Valley’s eight-square-mile watershed area, including the city of Mill Valley, Richardson Bay and the unincorporated community of Homestead Valley.

The Mill Valley StreamKeepers strives to reach its goals by direct activities, including restoration projects, monthly meetings, monitoring of creeks and property construction, clean-ups, newsletters, and communications with local and county agencies. An important means to accomplish our direct activities is by the education of the Mill Valley citizenry about Mill Valley’s network of streams, creeks, marshes, lakes and reservoirs, through such events open to the public as periodic creek walks, presentations to neighborhood associations and participation in public gatherings.

We invite you to share the StreamKeepers’ vision, enthusiasm and expertise in this field, to become aware of, and perhaps advocates for, this important aspect of the town’s quality of life, and to join in protecting and improving our environment, for Mill Valley’s current and future citizens, animals and plant life.

Please consider participating in our far-reaching goals. The Mill Valley StreamKeepers welcomes all interested citizens to our organization, to join in monthly meetings, public issues committees, research, grant writing, public outreach, creek monitoring and other foreground and background activities that will help us ensure a healthy Mill Valley environment. If you would like to help or find out additional information before making your decision, please contact us.

Our regular board meetings are held on the second Saturday of each month from 10am to noon in the Community Room of the Sewerage Agency of Southern Marin (SASM), 450 Sycamore Avenue, Mill Valley. The public is welcome to attend and to bring comments and concerns to the meeting. While a good portion of what we do requires our time and effort, financial needs exist too. Contributions for ongoing costs for our post office box, phone service, newsletters and materials, as well as our watershed planning projects, are appreciated by our 100% volunteer organization. Contributions are used solely for the organization’s advocacy and public education uses. To contribute, please send checks to:
