These nearly level soils are on bottom lands and flood plains of all
the major streams in the survey area . The Aquolls , which have dark
colored surface layers , make up about 65 percent of the mapping unit.
The Aquents , which have lighter colored surface layers , make up about
25 percent . About 10 percent is Aquolls and Aquepts , flooded , and
Bankard sandy loam.
These are deep, poorly drained soils . They formed in recent alluvium.
tTypically they have mottled , mildly to moderately alkaline , loamy or
clayey surface layers and underlying material , and are underlain by f
sand or sand and gravel within 48 inches . They may or may not have a
gleyed layer in the underlying material. .
Most of tlicse soils are subject to flooding. A watcrtablc is at or

near the surface early in the spring and recedes to as deep as 48 j
f
Inches by la`e fall in some years .
These soils are used for rangeland and wildlife habitat . Some small
areas have been reclaimed by major drainage and leveling operations
I
and is farmed to irrigated crops.
The potential native vegetation on these soils is dominated by alkali �
sacaton, switchgrass and western whentgrass . Saltgrass, sedge , rush
and alkali bluegrass are also prominent. Potential production ranges
1 from 3000 pounds per acre in favorable years to 2000 pounds per acre
in unfavorable years . When range condition deteriorates , switchgrass ,
