These are the Assumption, Atlas, Keller, and Ogle soils. The well drained or moderately well drained Assumption soils are upslope or at higher elevations than Coatsburg soils. The somewhat poorly drained Atlas and Keller soils, and the well drained Ogle soils are on similar slopes nearby. Atlas soils are the forested member of a biosequence with Coatsburg soils. Coatsburg soils are poorly drained.
Permeability is very slow.
Surface runoff potential is medium or rapid. At undisturbed sites there is a perched water table at depths of 0 to 1.0 feet during the spring in most years. These soils are seasonally wet and seepy. Most areas are used for pasture or for forages that are cut for hay. Cultivated crops are on some of the less sloping areas.
