Welcome to Lake Sonoma


Many of you are making plans for the upcoming 4th of July holiday and want to know what the status of Lake Sonoma's campgrounds are. At this time, we are in alignment with the County Health Order stating that recreation campgrounds must remain closed (Section 16, C., v., #4).
* Campground closures have been scheduled through June 30th with refunds already issued.
* No new reservations are being accepted on for the month of July. This is to prevent additional cancellations in the event we need to extend the closure past June 30th.
* Even if there is a change in the County Health Order, we anticipate the closure extending through at least the 15th of July. The camping reservation system is still recovering from COVID and is understaffed with reduced operating hours of 1000-1830 EST Mon-Sat and closed on Sundays. Visitors are encouraged to use the online system rather than calling 1-877-444-6777. If campers choose to initiate a request for refund, they will be charged a service fee, if the campground initiates a closure/refund they will receive a full refund.

In accordance with the latest update to the Sonoma County Health Order, Lake Sonoma will start opening parts of the park for public use. The plan is to open the Public Boat Ramp and Marina for lake surface use on Saturday, May 16, 9 AM. The Visitor Center Parking lot will be open for vessel inspections only. At this time, all other recreation areas will remain closed. Visitors are advised that all social distancing requirements in the health order must be observed in using Lake Sonoma. The opening of other areas will be done in phases and in consideration of the volume of visitors as a result of opening. Lake Sonoma reserves the right, in accordance with Sections 13 and 16 of the Order to re-close or not open areas if visitor use presents an unacceptable risk. Please follow the Health Order:
* Maintain a minimum six-foot distance from persons who are not part of the same household or living unit.
* Carry facial coverings at all times and wear them in all circumstances required by the Health Officer’s Order No. C19-07, including specifically if or when unable to maintain a six-foot distance from others (such as when passing on a trail).
* Do NOT use any facilities or equipment that are closed.
* Do NOT engage in sports or other activities that involve the use of shared equipment with individuals or groups outside of the person’s household.

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.
