l 34 U- Aquolls and Aquepts , flooded
These nearly level soils are on smooth plains in depressions and along
the bottoms of natural drainageways throughout the survey area. The
Aquolls , which have dark colored surface layers , make up about 55
percent of the mapping unit . The Aquepts , which have lighter colored
surface layers , make up about 25 percent. About 20 percent is made

I
up of soils which are well drained and soils which have sandstone or i
' shale within 48 inches of the surface .
These are deep , poorly drained soils . They formed in recent alluvium.
Typically they have mottled , mildly to moderately alkaline , loamy or
I
clayey surface layers and underlying materials which extend to a depth I
of 60 inches or more . They may or may not have a gleyed layer in the
underlying material.
Most of these soils are subject to excessive runoff. A watertable is
at or near the surface in the spring and luring the peak of the irri- ,

gation season.
These soils are used for rangeland and wildlife liabitat . Some small
areas are used for irrigated pasture.

The potential native vegetation on these soils is dominated by switch
grass , prairie cordgrass , saltgrass , alkali sacaton , big bluestem,

Indiangrass , western wheatgrass , slender whcatgrass , sedge and rush.
Cattails and bullrush occur on swampy spots associated with this site.
