The poorly drained Wynoose soils are on flats of the till plains. The Bluford and Wynoose soils form a hydrosequence with Ava soils. In Indiana the Ava soils are also associated with the well drained Cincinnati , moderately well drained Shakamak , and the somewhat poorly drained Vigo soils. Moderately well drained. Runoff is medium or rapid.
Permeability is moderate in the upper part of the solum and very slow in the fragipan.
Depth to an intermittent perched high water table is at 1.5 to 3.5 feet from January through April in most years. Many areas of Ava soils are cultivated. Corn, soybeans, small grain, and pasture are the main crops. Some areas are in woodland. Native vegetation is deciduous trees.
