Slopes range from 0 to 1 percent. Mean annual temperature ranges from about 47 to 56 degrees F, and mean annual precipitation ranges from 26 to 32 inches. These are the competing Blencoe , Calco , Colo , Luton , and Solomon soils and less frequent associates are the Cooper and McPaul soils. Cooper soils are in slightly higher, better drained parts of the landscapes. McPaul soils are light colored, silty soils of low clay content.
Natural drainage is poor and very poor.
Runoff is very slow. They are moderately slowly permeable in about the upper 2 feet and very slowly permeable below. Some flood hazard exists from tributary water that flow across areas of these soils to the main stream. Usually these are manmade ditches. Most areas of these soils are used for cultivated crops.
