The Little Rock Creek Watershed lies
within the North Central Harwood Forest
ecoregion, within the Mississippi River
- Sartell watershed. Located North of
St. Cloud, MN, the 67,650 acre watershed
is nearly evenly split between Benton
and Morrison Counties with 36,030 acres
in Benton County and 31,620 acres in
Morrison County. Land use within the
watershed consists of 60% cultivated
land, 20% grassland, and 14% forested
land. Only 2.4% of the land is urban and
residential, according to the Land
Management Information Center's 1989
land use data.
Animal agriculture operations within
this watershed include poultry, hog, and
dairy operations located on marginal
soils which require careful management.
Irrigated cash crops consisting of corn,
soybeans, rye, wheat, potatoes, and
kidney beans are being grown in this
area. Soils in this area have high
infiltration rates which increase the
potential for ground water
contamination. Supplemental moisture is
needed, in most cases, to produce a
profitable crop. These soils are located
primarily in the western half of the
watershed.
In general, the headwater portions of
the watershed are located in glacial
till, consisting of drumlin landforms.
Soils tend to be sandy loam in texture
and exhibit inherently high phosphorus
levels. The landscape is moderately
steep with slopes of 2 to 6 percent.
Wetlands are abundant in these areas as
well, although many have been drained to
various degrees. The lower reaches of
the streams generally are located in
glacial outwash. Soils are sandy with
nearly level slopes. A high percentage
of cropland in the sandy western areas
of the watershed is irrigated.

the Minnesota Pollution Control Agency
(MPCA) to conduct the Little Rock Creek
