Join the Friends of Lake Sonoma!

The Friends of Lake Sonoma is a non-profit organization made up of people like you who love Lake Sonoma and want to make it even better by providing added educational and recreational opportunities.  We need your unique skills and financial support to continue our existing programs and create new ones to make everyone's Lake Sonoma experience the best it can be.

Our volunteers help us staff the Milt Brandt Visitors Center, maintain trails, host special events -- like our annual Lake Sonoma Steelhead Festival -- and lead fish hatchery tours.  Our membership fees and cash donations allow us to build eductional displays, conduct campfire programs, maintain existing park facilities and build new recreational venues. 

With government cutbacks, park budgets are becoming increasingly stressed and Lake Sonoma is no exception.  This means we must rely on you to help support our mission.  Your tax-deductible membership will help the Friends of Lake Sonoma enhance the visitor experience, as well as provide funding for public education programs, volunteer support, and park projects and services.
