This soil formed in loamy and sandy glaciofluvial deposits. The Wasepi soils are the somewhat poorly drained member of a drainage sequence that includes the well drained Boyer, moderately well drained Perrin, and poorly drained Gilford soils. Brady, Oshtemo, and Sebewa soils are closely associated on outwash plains. Somewhat poorly drained. Surface runoff is slow.
Permeability is moderately rapid in the solum and rapid in underlying sand and gravel.
Soils are cultivated in most areas. Corn, soybeans, small grain, and grass-legume hay are principal crops. Soils are used for permanent pasture or forest in a few areas. The native vegetation was hardwoods, principally American elm, white ash, hickory, and swamp white oak. The series is of large extent.
