The moderately well drained Catlin, Dana, and Saybrook soils, the somewhat poorly drained Flanagan, Lisbon, and Raub soils, and the well drained Sidell soils formed in loess and in the underlying loamy till. In drained conditions, an apparent seasonal high water table is 0.5 foot above the surface to 1.0 foot below the surface at some time between January and May in most years. In undrained conditions, an apparent seasonal high water table is 0.5 foot above the surface to 0.5 foot below the surface at some time between November and June in most years. The potential for surface runoff is negligible or very low. Water ponds on these soils for brief periods during the spring.
Permeability is moderate.
Most areas are cropped. Corn and soybeans are the principal crops. Some areas are used for growing small grain or meadow. Native vegetation is hydrophytic grasses, reeds, and sedges. Northern and central Illinois, northwestern Indiana, southwestern Ohio and southeastern Wisconsin.
