LOCATION CAREY LAKE IDEstablished Series
The Carey Lake series consists of very deep, well drained soils that
formed in alluvium from mixed sources. Carey Lake soils are on level
to gently sloping alluvial fan terraces and have slopes of 0 to 4
percent. Permeability is moderately slow. The average annual
precipitation is about 14 inches, and the average annual temperature is
about 43 degrees F.

unless otherwise noted.)

5/3) fine sandy loam, dark brown (10YR 3/3) moist; many fine and medium
prominent yellowish brown (10YR 5/6) relic mottles; massive; slightly
hard, friable; few very fine and fine roots; few fine tubular pores;
neutral (pH 7.2); gradual wavy boundary. (5 to 14 inches thick)

grayish brown (10YR 3/2) moist; many fine and medium prominent
yellowish brown (10YR 5/6) relic mottles; massive; slightly hard,
friable; few very fine and fine roots; few fine tubular pores; neutral

COMPETING SERIES: Bly, Hades, and Strom. Bly and Strom have more than
10 percent rock fragments in the Bt horizon. Hades soils are deeper
than 28 inches to the base of the argillic. Strom soils are somewhat
poorly drained.
GEOGRAPHIC SETTING: Carey Lake soils are on nearly level to gently
sloping alluvial fans and terraces. Slopes range from 0 to 4 percent.
Elevation ranges from 4,700 to 6,000 feet. The soil formed in alluvium
from mixed sources. The average annual precipitation is 12 to 16
inches, most of which falls as snow and early spring rains. The
average air temperature is about 40 to 45 degrees F. The frost free
season is 70 to 90 days.
GEOGRAPHICALLY ASSOCIATED SOILS: Adamson, Balaam, Brinegar, Bruneel,
Hutton, and Little Wood. Adamson, and Balaam soils are well drained
and lack argillic horizons. Brinegar soils have less than 75 percent
base saturation in the upper 30 inches. Bruneel soils are somewhat
poorly drained and underlain by sands and gravels. Little Wood soils
are well drained and contain greater than 35 percent rock fragments in
the control section. Adamson and Balaam soils occur on low fan
terraces. Bruneel and Hutton soils occur on flood plains. Brinegar
and Little Wood occur on the same landscape as the Carey Lake soils.
DRAINAGE AND PERMEABILITY: Well drained. Runoff is slow.
Permeability is moderately slow.
USE AND VEGETATION: Mainly used for irrigated cropland. Crops include
small grains and alfalfa.
DISTRIBUTION AND EXTENT: South-central Idaho. The series is of
limited extent. Series proposed, Blaine County, Idaho, 1981.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Portland, Oregon
SERIES ESTABLISHED: Blaine County, Idaho, 1985.
REMARKS: Diagnostic horizons and features recognized in this series
are:
Mollic epipedon - the zone from the surface of the soil to a depth of
approximately 72 inches
Argillic horizon - the zone from approximately 12 to 28 inches (Bt
horizon)
A permanent change in drainage has lowered the watertable and this
series is well drained.
