Big Sulphur Creek is a westward-flowing stream in northern Sonoma County, California, U.S.A. which springs from The Geysers in the Mayacamas Mountains and runs convert|20|mi|km|0|lk=on to empty into the Russian River.

Course

The creek originates on Pine Mountain in the Geysers area, near the Lake County line. It descends to the west, passing north of Sheepskin Rock. North of Mercuryville, it meets Geysers Road, which it parallels the rest of the way to the City of Cloverdale. After Hot Springs Creek and Cobb Creek enter from the right, Big Sulphur Creek passes Geysers Resort and Eagle Rock. Then Truitt Creek enters from the left, Squaw Creek and Frasier Creek enter from the right, and Little Sulphur Creek enters from the left. Big Sulphur Creek emerges into the northern end of Alexander Valley and empties into the Russian River convert|2|mi|km|0 north of Cloverdale.

Watershed

The creek's drainage basin covers about convert|60|sqmi|km2|-1 in the Mayacamas Mountains in northern Sonoma County.

Habitat and pollution

When surveyed in 1973, Big Sulphur Creek supported snakes, salamanders, frogs, many kinds of fish (both steelhead and rainbow trout, Sacramento squawfish, suckers and roach), flies (trichoptera, diptera, hemiptera, plecoptera and odonata), and aquatic plants (sedges, cattails, and algae).

As of 2000, the creek and two of its tributaries (Little Sulphur Creek and Squaw Creek) still supported steelhead trout.
