About Us

Friends of Sonoita Creek (FOSC) was founded in 2004.  Its mission is to educate and protect the Sonoita Creek watershed. We inform residents and visitors about its importance to life forms and relationship to the geography through hands-on activities, presentations, hikes, and financial support to kindred organizations.


Support comes from around the country and even from British Columbia, CA.  The majority of members live nearby in Nogales, Rio Rico, Green Valley, Tubac, Tucson, Marana, Oro Valley, Sierra Vista, Tempe and Flagstaff as well.  Other members hail from California, Colorado, Massachusetts, Montana, Oregon, Pennsylvania, and South Dakota.      Thank you everyone!
