slow, and the erosion hazard is slight. These soils are used almost entirely as irrigated cropland,
though some small areas are used for grazing. Wind breaks and environmental plantings are
generally well suited to these soils. These soils are important for wildlife because of their
intensive use for cropland and their proximity to the South Platte River. Their primary value for
wildlife species is in the food they produce under irrigation and the utilization of crop residues
following harvest.

The Lebsack silty clay loam soils are deep, moderately well drained, nearly level soils found on
terraces. The permeability is slow. Available water capacity is high, surface runoff is slow, and
the erosion hazard is slight. Nearly all of this loam is used for irrigated cropland. Wind breaks
and environmental plantings are generally well suited to these soils. These soils are important
for wildlife because of their intensive use for cropland and their proximity to the South Platte
River. Their primary value for wildlife species is in the food they produce under irrigation and
the utilization of crop residues following harvest.

The Nunn clay loam soils are deep, moderately well drained to well drained, nearly level soils
found on terraces. The permeability is slow. Available water capacity is high, surface runoff is
slow, and the erosion hazard is slight. These soils are used almost entirely for irrigated cropland.
Wind breaks and environmental plantings are generally well suited to these soils. Openland
wildlife are suited to these soils where favorable habitat can be established in cropland for
nesting and escape cover.

The Satanta loam soils are deep, moderately well drained, nearly level soils found on terraces.
The permeability is moderate. Available water capacity is high, surface runoff is slow, and the
erosion hazard is slight. These soils are used almost entirely for irrigated cropland, with some
small isolated areas used for grazing. Wind breaks and environmental plantings are well suited
on these soils. Openland wildlife are suited to these soils where favorable habitat can be
established in cropland for nesting and escape cover.

The Westplain silty clay loam soils are deep, somewhat poorly drained, nearly level soils found
on low bottomlands and concave parts of low terraces. They are subject to frequent flooding in
the spring, and the permeability is slow. Available water capacity is moderate, surface runoff is
slow, and the erosion hazard is slight. These soils are used mainly for irrigated cropland and
grazing. Wind breaks and environmental plantings are generally well suited to these soils. The
soils are important for wildlife because of their use for cropland and their proximity to the South
Platte River. Their primary value for wildlife species is in the food they produce under irrigation
and the utilization of crop residues following harvest.
