Welcome to Lake Sonoma



EFFECTIVE IMMEDIATELY:  All boat-in campsites at Lake Sonoma have been closed while the U.S. Army Corps of Engineers searches for a new vendor to service water-borne sewage restrooms.   Lake Sonoma supplies drinking water to more than 600,000 residents of Sonoma and Marin Counties. For health and sanitary reasons, the Corps was required to shut down camping at the sites, which are normally accessed by boat, until a new vendor can be found.  The Corps is currently working to find a vendor to manage the floating and boat-in restroom service contract as soon as possible.

Alternate drive-in camping is still available at Liberty Glen Campground (877-444-6777) or the Lake Sonoma Marina Campground (707-433-2200).



Nestled in the beautiful coastal foothills of Sonoma County, California, Lake Sonoma is surrounded by world famous vineyards and land that is rich in history. Created by the construction of Warm Springs Dam in 1983, the lake provides for flood control, irrigation and recreation. When full, the lake has a surface area of more than 2,700 acres and 50 miles of shoreline, forming the perfect setting for a wealth of recreational activities. We invite you to hike, swim, ride, boat, camp, fish, or hunt at our beautiful lake.

The Warm Springs Cultural Resources Study was one of the first large projects conducted under federal historic preservation laws and regulations enacted in the 1960s. From 1974 to 1984, before the filling of Lake Sonoma behind Warm Springs Dam, the area was intensively studied by a team of archaeologists, cultural anthropologists, architectural historians, ethnobotanists, historians, and Native American traditional scholars. Before Warm Springs Dam was the last of many reports produced by that team, synthesizing the material for a general audience.

Unfortunately, by the time the report was completed in 1985, the U.S. Army Corps of Engineers had insufficient funds to distribute it as widely as intended. Funds for the envisioned future publication of the volume never materialized. A few years ago, the Anthropological Studies Center requested permission from the Corps to publish the volume elsewhere. This was granted and thus began the task of recreating a volume whose text resided on obsolete “elephant disks.” Rose White scanned the text from the original provided by the Corps. The authors proofread the text for the myriad minute errors that sneak into scanned text. Maria Ribeiro formatted the report, inserted the graphics, and made the final edits. Scotty Thompson and Richard Stradford helped us find elusive photographs.

Much as we were tempted to update the volume and revise sections we now know to be inaccurate or outdated, we agreed that such an effort would put the volume’s publication back another 15 years. So except for very minor technical edits, this is the Before Warm Springs Dam: A History of the Lake Sonoma Area as it was submitted to the U.S. Army Corps of Engineers in 1985.
