Caption: The Chart shows pool quantity by reach according to a habitat typing survey conducted in Upper Sonoma Creek in 1996. Blue bands show pool habitat length, green show non-pool habitat, and yellow shows dry habitat. Most of the pool habitat was found in Reach 2, which was also the longest surveyed reach. Reach 2 was comprised of 18% pool habitat. Pools comprised 14-20% of the habitat in each reach. Surveys followed CDFG methods and data provided in Southern Sonoma County RCD report.
