The flood plain soils do not have argillic horizons. Freeburg, Twomile and Okaw soils are somewhat poorly or poorly drained. Permeability is moderate. Runoff potential is negligible to low. In undisturbed areas the upper depth of an apparent water table is at 3.5 to 5 feet during November to April in most years.
Flooding is none, rare, or occasional.
Most areas are used for growing row crops, hayland or pasture. Native vegetation is hardwood forest. The series is of moderate extent. Audrain County, Missouri, 1991.
