Well drained Koronis soils are formed entirely in loamy glacial till and are closely associated on nearby convex positions. Poorly drained Granby soils are sandy to below 40 inch depth and are on plane and slightly concave positions. Very poorly drained Lundlake soils formed entirely in glacial till. Moderately well drained. Surface runoff is moderately low or moderately high.
Permeability is very rapid in the sandy mantle and moderately rapid in the underlying material.
An apparent seasonal high water table is at 2.5 to 4 feet at some time during April to July in most years. Most areas of these soils are cropped to corn and soybeans. A few areas are in pasture and woodland. Native vegetation is Northern hardwoods and tall grass prairie. These soils are of moderate extent.
