|This subaqueous soil is on lake beds and
shorelines of freshwater lakes, ponds, and reservoirs. Aquapaug soils
are sandy throughout and are formed in sandy glacial fluvial material.
Mapped areas are irregular in shape and range from 1 to 196 hectares (2
to 486 acres). Slope ranges from 0 to 3 percent.
Typically, this soil
has a very dark gray, grayish brown, or brown sand or sandy loam surface
layer, 10 to 40 cm thick. The substratum is very dark gray, gray, or
grayish brown loamy very fine sand or sand glacial deposits.
This soil is permanently submerged with up to 3 meters of fresh
water. All horizons have a pH of less than 6.0. Phosphorus concentration
in the upper 10 cm of the soil ranges from 21.9 to 238.9 ppm, with a
mean of 76.2 ppm. Carbon pools in the upper meter of Aquapaug soils
range from 11 to 103 Mg C ha-¹ with a mean of 56 Mg C ha-¹.
Included with this soil in mapping are small areas of Shannock soils
in lower energy basins, Shannock soils have higher fluidity and organic
matter in the surface layers. Small areas of Burlingame soils are
included where parent materials are derived from tills and have finer
particle size along with surface stones and boulders. Small areas of
Wickford and Tuckertown soils may also be included in areas where
organic layers overlie glacial parent materials below. Included areas
make up about 15 percent of this map unit.
Fishing and recreational boating are common in the areas within this
map unit. Most areas are vegetated with native and invasive submerged
aquatic vegetation including white pond lily, yellow pond lily,
bladderwort, pondweeds, rushes, wild celery, and variable milfoil. Some
areas are un-vegetated sandy bottom water bodies.
