PAtJMIA AREA, CULURAUU

come by the use of proper design and construction
methods.
This soil is in capability subclass Vlls, nonirrigated.
35-Fluvaquenta, flooded. The somewhat poorly
drained end poorly drained soils in this broadly defined
unit are in low, concave areas and on nearly level to
moderately slopiny flood plains of narrow, winding val-
leys. Slopes range from 0 to 10 percent. These soils
vary widely in texture, degree of mottling, and depth to
the water table.
The surface layer ranges from tine sandy loam to clay
loam. The underlying layers generally aro loam or heavy
clay loam and are stratified with sand, gravel, and cob-
bles, In some areas gravel and cobbles are near the
surface.
The depth to the water table ranges from 2 to 4 feet
and is near the surface during part of the year. These
soils are subject to rare or occasional flooding.
The native vegetation consists mainly of willow and
cottonwood and water-tolerant grasses, sedges, and
rushes.
In some areas these soils are artificially drained and
are used for crops. If drained, these soils are suited to
hay, small grains, pasture, orchard crops, and some row
crops. In some areas these soils are used for grazing of
livestock and wildlife and for recreational purposes.
Because annual precipitation is low and has poor sea-
sonal distribution, these soils are unsuited to nonirrigated
crops. However, nonirrigated pasture grasses can be
planted late in summer and in tall to protect the soil from
erosion and to provide grazing for livestock, if good pas-
ture management is practiced.
Areas of this map unit provide habitat for many kinds
01 wildlife. They provide cover for ring-necked pheasant
that feed in adjacent farmland. Mourning dove nest in
the cottonwoods and tamarisk that grow in these areas.
Restricting grazing of livestock helps to maintain the
quality of wildlife habitat in areas of these soils. Where
these soils are suitable for crops, establishment of food
plots, tree and shrub plantings, and nesting cover help to
improve habitat for upland wildlife. Where the water table
is high, open water areas can be developed to create
habits! for watertowl and shorebirds.
If these soils are used for urban development, the
main limitations are the high water table and hazard of
flooding. These limitations can be overcome by the use
of proper design and construction methods.
These soils are in capability subclass Vlw, nonirrigat-
ed.
36-Fluvents, flooded. The soils in this broadly de-
fined unit are in narrow, winding valleys, on small fans,
and on toe slopes of mountains. Slopes range from 0 to
6 percent. These soils are scattered throughout the
survey area. They are mainly well drained and consist of
an accumulation of valley-filling sediment derived from a
variety of rocks and upland soils. Some of the sediment
has been carried only a short distance by fast-moving

water, and sorting of soil particles and rock fragments is
slight. Some of the sediment has been carried a consid-
erable distance, and sorting and stratification are more
pronounced.
The surface layer generally is loamy but ranges from
moderately coarse textured to moderately fine textured.
Tho underlying layers are stratified end ere calcareous in
most plates.
Some areas of these soils are subject to flooding and
to further deposition of Sediment. In most areas the
development of soil horizons is slight. In some areas,
however, these soils have a dark colored surface layer
and a blocky subsoil. Gullies form where the soils ere
not protected by a vegetative cover. Available water ca-
pacity is moderate to high.
The native vegetation commonly consists of adapted
shrubs and grasses. These soils are used for range,
recreational purposes, and wildlife habitat.
Because annual precipitation is low and has poor sea-
sonal distribution, these soils are not suited to nonin•igat-
ed crops. Where native grasses have been depleted or
destroyed, however, a high degree of success ten be
expected from pasture plantings of nonirrigated grasses
in spring, late in summer, and in fall to protect the soils
from erosion and to provide grazing for livestock. Good
management must be practiced to maintain the grasses.
Pubescent wheatgrass, tall wheatgrass, end crested
wheatgrass are adapted species.
Arees of these soils provide habitat for many kinds of
wildlife. They provide cover for ring-necked pheasant
that feed in adjacent farmland and nesting sites for
mourning dove. Restricting grazing of livestock helps to
maintain the quality of wildlife habitat in these areas.
Where these soils are suitable for crops, lood plots,
trees and shrubs, and nesting cover can be established
to improve habitat for upland wildlife.
If these soils are used for urban development, the
main limitation is the hazard of flooding. This limitation
can be overcome by the use of proper design and con-
struction methods.
These soils are in Capability subclass Vlw, rtoninigat-
ed.
37-Fughea loam, 5 to 15 percent slopes. This is a
deep, well drained soil. It formed in old alluvial fan and
landslide deposits derived from sedimentary rock and is
on alluvial fans, valley side slopes, and uplands. Eleva-
iion ranges from 6,500 to 8,500 feet. Average annual
precipitation is about 18 inches, average annual air tem-
perature is about 42 degrees F, and the average frost-
free season is about 100 days.
Typically the surface layer is very dark grayish brown
loam about 5 inches thick. Tha subsoil is dark grayish
brown clay loam that grades to reddish brown light clay
and is shout 39 inches thick. The substratum, to a depth
of 60 inches, is light reddish brown clay loam.
Permeability is slow, and available water capacity is
high. Effective rooting depth is 60 inches or more. Sur-
