About
The race
Lake Sonoma was created in 1983 by the construction of the Warm Springs Dam. At capacity, the lake covers 2,700 acres and offers 50 miles of coastline. Managed by the US Army Corps of Engineers, over 17,000 acres of lake and surrounding recreation area offer a wide variety of activities, including hiking, mountain bike and horseback riding, boating, camping, fishing and hunting. More than 40 miles of hiking, biking and equestrian trails meander around the two main arms of the lake, taking in rolling coastal foothills of redwood groves, oak woodlands, mixed forests, grassy slopes and steep hills. The lake features some of the best bass fishing in the state, along with steelhead, trout, catfish and perch. Lake Sonoma has 109 primitive campsites and two group-use campsites that are accessible by boat and/or trail only. One drive-in campground is also available.
