Brush Creek or Rincon Creek is a tributary of Santa Rosa Creek in Sonoma County, California. Brush Creek rises in the southern slopes of the Mayacamas Mountains within Sonoma County. The lower reach of the creek is a suburban medium density residential area in the city of Santa Rosa, and that reach of Brush Creek has been restored during the 1990s under a U.S. Environmental Protection Agency grant to promote steelhead migration and spawning. Further restoration and incorporation into citywide park planning is currently underway as of 2006. The location of the confluence with Santa Rosa Creek is particularly noteworthy, since it was a locus of prehistoric life as a village of the Pomo people and a scenic geologic feature of massive flat boulder outcrops within the stream channel. Brush Creek is a watercourse of approximately three miles in length that drains the area known as Rincon Valley in north Santa Rosa and the outlying unincorporated areas. The stream is shown on U.S. Geological Survey topographic maps as Rincon Creek. On current maps, Rincon Creek is a tributary that forms a confluence with Brush Creek approximately four kilometers upstream from the mouth of Brush Creek (near Montecito Boulevard). Thus today's nomenclature makes Rincon Creek essentially the west fork of upper Brush Creek.

Lake Ilsanjo is a man-made lake located in Annadel State Park east of Santa Rosa in Sonoma County, California, United States. It is a place for fishing and swimming, especially in the summer months. Entrepreneur Joe Coney originally owned the land that is now Annadel State Park and named the lake after his wife Ilsa and himself. Thus it came to be called Lake Ilsanjo. It drains into Spring Creek. The lake is formed by a dam constructed in the 1950s. Originally the overflow drained to a gully during the winter months, but in 2003, the state spent almost $400,000 building a spillway and release valve to reduce downstream erosion. During the winter of 2007–08, park officials accidentally left the release valve open, causing the lake level to drop far below normal, exposing mudflats that would normally be underwater.

Trione-Annadel State Park is a state park of California in the United States. It is situated at the northern edge of Sonoma Valley and is adjacent to Spring Lake Regional Park in Santa Rosa. It offers many recreational activities within its 5,092-acre (2,061 ha) property. The rock formations of Trione-Annadel have played a central role in its history: its volcanic origins, the Native American use of obsidian, the early 1900s mining of cobblestones, and modern hikers' appreciation of its volcanic rock outcrops. These lands were occupied by the Wappo and Pomo people in prehistoric times, who would have primarily inhabited the riparian zones and the marsh perimeter. Annadel includes what some biologists consider the best example of undisturbed northern oak woodlands in existence. Visitors can enjoy the park's diverse wildlife and scenery during any time of the year but are perhaps most rewarded from April through June when most wildflowers are in bloom. The park has gone through two Wildfires in its history, the 2017 Nuns fire that burned the majority of the park and the most recent Glass fire in 2020.

At 04:56 and 06:19 UTC on October 2, 1969 (21:56 and 23:19 PDT October 1), a pair of earthquakes of magnitude 5.6 and 5.7, respectively, struck the city of Santa Rosa, California, killing one person and damaging buildings.

The $8.35 million cost of the earthquakes went mostly to replace buildings damaged beyond repair. There were at least 200 aftershocks after the initial pair of earthquakes. At the time they were the largest earthquakes to affect the northern San Francisco Bay Area since the 1906 San Francisco earthquake.
