Events at Lake Sonoma


From January through April, guided tours for school children and other groups are available weekdays by appointment.  Self-guided tours are available every day.  The fish hatchery sorts fish daily and does its artificial spawning on Thursday mornings.  To watch the magnificent steelhead push their way up Dry Creek to the fish ladder to spawn the next generation of fish, come out to the park or call 707-431-4533 to make an appointment for a guided group tour! Tours are free.

Want to hold an event at Lake Sonoma?

Lake Sonoma is the perfect venue for all kinds of events, ranging from family reunions to mountain bike racing. Fees for venue rental are set by the U.S. Army Corps of Engineers, but if you're planning an event, you can designate the Friends of Lake Sonoma as an event sponsor and your fees will then be a donation -- with all funds returned directly to the park in support of programs and maintenance.  

To hold an event, contact the USACE at 707-431-4590 and mention to the park ranger that you would like to partner with the Friends of Lake Sonoma.  It's as simple as that!
