The potential for surface runoff is medium on the gentle slopes and rapid on the steeper slopes. Permeability is moderate in the solum and moderately slow in the underlying material. An intermittent perched high water table is at a depth of 2.0 feet to 3.5 feet in most years. Most areas are cultivated, but some are in pasture and woodland. The principal crops are corn, soybeans, small grain, or hay.
Native vegetation is hardwood forest.
McHenry County, Illinois, 1996. Kidami is a coined name that has intermediate properties of Kidder and Miami series. This soil was formerly mapped Miami in McHenry County. Through MLRA update activities these areas were determined to have moderately slow permeability whereas the Miami series has slow or very slow permeability in the underlyng dense basal till. Water table data indicates that this soil has a perched water table at a depth of 1.0 foot to 3.5 feet in late winter and in early spring.
