Canisteo, Webster, and Harps soils are higher in sand content, lower in clay content, and have thinner dark surface layers. They are on concave slopes above the Okoboji soil. In many places, Harps soils form a convex shoreline rim around the Okoboji soils. Palms and Wacousta soils are in landlocked depressions. Palms soils formed in sapric material.
Wacousta soils have a thinner A horizon.
Very poorly drained. Runoff is negligible. Permeability is moderately slow. Where drained they are cultivated to corn, soybeans, and small grain. Native vegetation is water tolerant grasses and sedges.
