Support Friends of Lake Sonoma

There are multiple ways YOU can make a difference and support the Friends of Lake Sonoma!

Direct Financial Donations

Donations to Friends of Lake Sonoma are tax deductible.  All money donated goes directly to support park projects, free of Federal intervention.  This helps us keep the Milt Brandt Visitors Center and Congressman Don Clausen Fish Hatchery open to public access, as well as build, maintain and improve new and existing park facilties to enhance the visitor experience. 

Donations should be mailed to Friends of Lake Sonoma, 3288 Skaggs Springs Road, Geyserville, CA  95441.

Weddings, Festivals, Events and Venue Rental Fees

If you are holding an event at Lake Sonoma, you have the option of having your venue rental fees donated to the Friends of Lake Sonoma by naming us as a sponsor of your event. Simply make the request at the time you book your event with the park rangers. 

There are several benefits.  You or your organization can get a tax deduction for the donation, the fees will go directly back to the park to support park maintenance and you will have made an important contribution to keeping Lake Sonoma open!

Volunteer Your Time
