The very poorly drained Adrian and Houghton soils formed in organic material and are in deeper depressions. The excessively drained Chelsea and Plainfield soils, the somewhat excessively drained Coloma soils, and the well drained and moderately well drained Oakville soils are on higher lying swells and dunes. The somewhat poorly drained Morocco and Watseka soils are on swells on outwash plains. Poorly drained and very poorly drained. The potential for surface runoff is negligible.
Permeability is rapid.
An intermittent apparent high water is 2 feet above the surface to 1 foot below the surface in most years. Mostly used to grow corn, soybeans, and wheat. Many areas that are drained are irrigated. Native vegetation is marsh grasses, reeds, sedges, and water-tolerant trees. In Northern Indiana, southern Michigan, southern Wisconsin and northeastern Illinois.
