 GEOGRAPHIC SETTING: St. Charles soils are on summits and side slopes of loess covered outwash plains, till plains, and stream terraces. Slopes commonly are 0 to 15 percent, but some are as steep as 30 percent. St. Charles soils formed in 102 to 152 cm (40 to 60 inches) of loess and in the underlying loamy stratified outwash or sandy loam till thought to be of Wisconsin Age. The substratum commonly is stratified loamy outwash, but in some pedons is gravelly or sandy outwash or sandy loam till. Mean annual temperature ranges from 7.8 to 12.2 degrees C (46 to 54 degrees F), mean annual precipitation ranges from 762 to 1067 mm (30 to 42 inches), frost-free period ranges from 160 to 180 days, and elevation ranges from 207 to 311 meters (680 to 1020 feet) above mean sea level. 
 
-GEOGRAPHICALLY ASSOCIATED SOILS: These are the Batavia, Camden, Kendall, Kidder, McHenry, Sexton, Starks, and Thorp soils. Batavia soils have a dark-colored surface layer and commonly are upslope from St. Charles soils and farther from the drainageways. Camden soils are nearby on similar landscapes that have a mantle of loess 51 to 102 cm (20 to 40 inches) in thickness. Kendall soils are the somewhat poorly drained member of a hydro-sequence with St. Charles soils. Kidder and McHenry soils formed in sandy loam till on similar topographic positions as some St. Charles soils, but average more than 15 percent fine sand and coarser in the control section. The poorly drained Sexton and somewhat poorly drained Starks soils are on outwash plains and stream terraces nearby, and have chroma of 2 in the upper part of the sola. The nearly level, poorly drained Thorp soils have a thinner mantle of loess and are Argiaquic Argialbolls.

 DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. An apparent water table is at a depth of 107 to 183 cm (3.5 to 6 feet) at some time between February and June, or at depths greater than 183 cm (6 feet). The potential for surface runoff is very low on areas of less than 5 percent slopes and low on areas of 5 to 20 percent slopes. Saturated hydraulic conductivity is moderately high to high (4.23 to 14.11 micrometer per second). The areas of St. Charles series mapped as sandy and gravelly substratum phases have saturated hydraulic conductivity in the substratum as high to very high (42.34 or more micrometers per second). Permeability is moderate in the solum. The permeability is moderate in the 2C horizon of soils with loamy substratum, rapid in the 2C horizon of soils in the sandy substratum phase, and very rapid in the 2C horizon of soils in the gravelly substratum phase. 
 
 USE AND VEGETATION: Many areas are cultivated. The principal crops are corn, soybeans, small grain, and meadow. Some areas are in pasture or woodland. The soils formed under forest vegetation. 
 
 DISTRIBUTION AND EXTENT: Illinois, Indiana, and Wisconsin in MLRAs 95B, 108A, 108B, 110, 111D, and 115C. The extent is large.
