Davison, Harps, and Wakonda soils have a calcic horizon within depths of 16 inches and are at edges of depressions. Worthing soils do not have E horizons and are in the lower, more poorly drained positions. These soils are ponded after heavy rains and melt waters from snow. Surface drainage is ponded. These soils typically are wet except in late summer and fall unless they have been drained.
Permeability is slow.
Water tables range from 1 foot above the surface to 4 feet below the surface in the spring of most years. Largely cropped when drained. Small grain, tame grasses, corn, and sorghum are the most common crops. Native vegetation is mainly prairie cordgrass, western wheatgrass, sedges, reedgrasses, bluegrasses, and forbs. Central and southeastern South Dakota east of the Missouri River.
