Link to Official Soil Series Description for Burlingame Soils

This subaqueous soil is on lake beds and shorelines of freshwater lakes, ponds, and reservoirs. Burlingame soils are formed in stony and boulder loamy glacial till material. Mapped areas are irregular in shape and range from 0.5 to 40 hectares (1 to 100 acres). Slope ranges from 0 to 3 percent. Surface stones and boulders typically cover 1-15 percent of the map unit with some areas consisting of boulder pavement (rubbleland).

Typically, this soil has a very dark gray, grayish brown, or brown sand or sandy loam surface layer, 20 to 40 cm thick. The substratum is very dark gray, gray, or grayish brown silt loam, sandy loam, or sandy glacial till deposits.

This soil is permanently submerged with up to 3 meters of fresh water. All horizons have a pH of less than 6.5. Phosphorus concentration in the upper 10 cm ranges from 16.8 to 743.5 ppm with a mean of 153.8 ppm. Carbon pools in the upper meter of Burlingame soils ranges from 23 to 340 Mg C ha-� with a mean of 152 Mg C ha-�.

Included with this soil in mapping are small areas of Shannock and Aquapaug soils in areas in sandy glacial fluvial material. Small areas of Wickford and Tuckertown soils may also be included in areas where organic layers overlie glacial parent materials. Included areas make up about 15 percent of this map unit.

Fishing, swimming, and diving 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, floating hearts, variable pondweed, fanwort, and variable milfoil. Turtles are often found perched on the boulder outcrops of this soil.
