Appendix F: Williams Creek Watershed--Soil Units Appendix F relates to the “General Soil Map” as seen in Josephine County Soil Survey. This map is show at the end of these soil unit descriptions. Takilma-Foehlin-Kerby (Map Unit 2) This soil unit is mainly found on low stream terraces and alluvial fans in the Williams Creek Watershed. These soils formed in alluvium derived from altered sedimentary and extrusive igneous rock. Characteristics: Deep, well-drained cobbly loam, gravelly loam, and loam Slopes: 0-12 % Depth to bedrock: 40 inches or more Elevation: 800-3,000 feet Average annual precipitation: 30 to 60 inches Frost-free season: 140-170 days Erosion hazard: slight Pollard-Abegg (Map Unit 4) This soil unit is mainly found on high stream terraces and hill sides in the Williams Creek Watershed. These soils formed in alluvium and colluvium derived from altered sedimentary and extrusive igneous rock. Characteristics: Deep, well-drained loam and gravelly loam Slopes: 2-20 % Depth to bedrock: 40 inches or more Elevation: 800-3,000 feet Average annual precipitation: 30-60 inches Frost-free season: 140-170 days Erosion hazard: slight Holland-Barron-Siskiyou (Map Unit 6) This soil unit is mainly on hill sides, toe slopes and alluvial fans. These soils are formed in alluvium, colluvium, and residuum derived from granitic rock. Characteristics: Deep and moderately deep, well drained and somewhat xcessively drained sandy loam, coarse sandy loam, and gravelly sandy loam. Slopes: 2-35 % Depth to bedrock: 40-60 inches Elevation: 800-3,000 feet Average annual precipitation: 30-40 inches Frost-free season: 120-170 days Erosion hazard: high Williams Creek Watershed Assessment 22
