The well drained Occum and the poorly drained Rippowam soils are associated in a drainage sequence. Agawam, Enfield, Haven, Hinckley, Merrimac, and Windsor soils are better drained and are on nearby outwash terraces. Saco soils are silty floodplain associates. Suncook soils are sandy, excessively drained soils on floodplains. Moderately well drained.
Surface runoff is slow.
Permeability is moderate or moderately rapid in the loamy upper layers and rapid or very rapid in the sandy substratum. Most areas of these soils flood for short periods each year. Soils on higher positions flood occasionally. Cleared areas are used for cultivated crops, hay, or pasture. Common trees in wooded areas are white pine, white, yellow, and gray birch, red maple, elm, alder, and hemlock.
