Runoff is low on slopes less than 1 percent, medium on 1 to 3 percent slopes, and high on 3 to 5 percent slopes. The overwash and depressional phases are somewhat poorly drained. The soil floods rarely or commonly, except where protected. Mainly used as cropland for production of cotton, sorghum, corn, and soybeans. Some areas are used for improved pasture of bermudagrass, dallisgrass, and white clover.
Native vegetation is pecan, elm, hackberry, oak, and ash trees and mid and tall grasses.
The series is of large extent. Classification change from mixed to smectitic based laboratory data from Colorado County and Washington County.
