SOIL SURVEY
floodwaters are shallow, and the floods are of brief dura-
tion.
Typically, the surface layer is a moderately alkaline,
dark grayish brown loam 21 inches thick. To a depth of
32 inches, the soil is moderately alkaline, dark grayish
brown clay loam, and there are thin strata of brown
sandy loam. To a depth of 53 inches, the soil is moder-
ately alkaline, grayish brown sandy clay loam, and there
are thin strata of fine sand. To a depth of 80 inches, the
soil is mottled, dark gray and dark yellowish brown, mod-
erately alkaline sandy clay.
Permeability is moderate, and the available water ca-
pacity is high. Runoff is slow, and the hazard of erosion
is slight.
Included in mapping are small areas of Frio and Trinity
soils. The included soils make up less than 15 percent of
any one mapped area.
This soil is used mainly as pasture, for which it has
high potential. It is well suited to improved bermuda-
grass. This soil has high potential for crops. If this soil is
used for crops, leaving crop residue on the surface will
help to conserve moisture and maintain tilth and produc-
tivity.
This soil has low potential for urban uses because of
the hazard of flooding and the corrosivity of the soil to
uncoated steel. The flooding is a limitation that is difficult
to overcome. Limitations to recreation uses are the
clayey surface texture and the hazard of flooding.
This soil is in capability subclass IIw and in the Loamy
Bottomland range site.
40-Gowen loam, frequently flooded. This a a deep,
well drained, nearly level soil on flood plains. The areas
are long and narrow and range from 15 to 40 acres. This
soil generally is flooded one or more times each year.
The floodwaters are shallow, and the floods are of brief
duration.
Typically, the surface layer is neutral, brown clay loam
4 inches thick. To a depth of 35 inches, the soil is
moderately alkaline, dark grayish brown loam and there
are a few thin strata of brown clay loam. To a depth of
53 inches, the soil is moderately alkaline, grayish brown
sandy clay loam, and there are common thin strata of
fine sand. To a depth of 80 inches, the soil is moderately
alkaline, dark gray and dark yellowish brown sandy clay.
Permeability is moderate, and the available water ca-
pacity is high. Runoff is slow, and the hazard of erosion
is slight.
Included in mapping are small areas of Frio and Trinity
soils. The included soils make up less than 20 percent of
any one mapped area.
This soil is used as pasture, for which it has high
potential. The yield of forage is high. This soil is well
suited to improved bermudagrass. This soil has low po-
tential for crops, mainly because of the hazard of flood-
ing.
This soil has very low potential for urban and recrea-
tion uses. The hazard of flooding and the corrosivity of
the soil are the main limitations.This soil is in capability subclass Vw and in the Loamy
Bottomland range site.
41-Helden clay, 1 to 3 percent slopes. This is a
deep, well drained, gently sloping soil on uplands. The
areas are oblong and range from 15 to about 200 acres.
Typically, the surface layer is moderately alkaline, dark
gray clay 6 inches thick. To a depth of 37 inches, the
soil is moderately alkaline, very dark grayish brown clay.
To a depth of 56 inches, it is moderately alkaline, grayish
brown clay that has gray and yellowish brown mottles.
The underlying material, to a depth of 78 inches, is shaly
clay mottled in shades of gray and yellow.
Permeability is very slow, and the available water ca-
pacity is high. Runoff is medium, and the hazard of
erosion is moderate.
Included in mapping are small areas of Normangee,
Houston Black, and Wilson soils. The included soils
make up less than 10 percent of any one mapped area.
This soil is used mainly as cropland and pasture. It has
high potential for these uses. The yield of forage and
crops is high if the soil is properly managed. Crop resi-
due should be left on the surface to help control runoff
and erosion and to maintain tilth and productivity. If this
soil is used for row crops, terraces and contour farming
are needed. This soil is well suited to improved bermuda-
grass. This soil is well suited to use as rangeland. The
climax plant community consists of tall and mid grasses.
This soil has low potential for urban uses. The very
high shrink-swell potential, corrosivity, and low strength
of the soil are limitations. In addition, the walls of cuts
and excavations tend to cave in or slough. These limita-
tions can be overcome through good design and careful
installation. This soil has low potential for recreation
uses. The clayey surface texture is the main limitation.
This soil is in capability subclass lie and in the Black-
land range site.
42-Helden clay, 2 to 5 percent slopes, eroded.
This is a deep, well drained, gently sloping soil on up-
lands. The areas are mainly oblong to long and narrow
and range from 15 to about 100 acres. In most areas,
erosion has removed about 50 percent of the surface
layer. Shallow gullies are common and are 20 to 60 feet
apart. There are deep gullies in some mapped areas.
Typically, the surface layer is moderately alkaline, dark
gray clay 6 inches thick. To a depth of 37 inches, the
soil is moderately alkaline, dark grayish brown clay. To a
depth of 56 inches, it is moderately alkaline, grayish
brown clay. The underlying material, to a depth of 78
inches, is shaly clay that has gray and yellow mottles.
Permeability is very slow, and the available water ca-
pacity is high. Runoff is rapid, and the hazard of erosion
is severe.
Included in mapping are small areas of Ferris soils.
The included soils make up less than 20 percent of any
one mapped area.
This soil is used mainly as pasture, for which it has
medium potential. It is well suited to improved bermuda-26
