Surficial geology of the Cane Creek basin, Lauderdale County, Tennessee

The surficial geology of the Cane Creek basin, in Lauderdale County, West Tennessee, was studied from 1985-88. Peoria Loess is the parent material from which soils in the Cane Creek drainage basin were derived. In general, a brown silt grades into a gray silt from 5 to I7 feet below ground surface. This color change probably represents depth to water table prior to the channelization of Cane Creek. Only at river mile 11.9 does rock outcrop near the main channel. Lower reaches of major tributaries have surficial geology similar to the main channel. In upper reaches of Hyde Creek and Fain Spring Creek, the sequence from the surface is sand and gravels, red-brown sandstone, sand and clay layers, and then, an orange sand layer. Coarse-grained deposits are found most often along the northern boundary of the basin and only occasionally in areas to the west and south of the main channel. Depth to sand or gravel ranges from about 0 to 158 feet in the uplands, and generally deeper than 40 feet near the main channel.

Preliminary assessment of ground-water resources of Lauderdale County, Tennessee

The ground-water resource in Lauderdale County is in a rudimentary stage of development. The principal shallow aquifers are the Mississippi alluvial deposits of Quaternary age and the Cockfield Formation, Memphis Sand, and Fort Pillow Sand of Tertiary age. Water levels fluctuate seasonally. High water levels generally occur in the winter, spring, or early summer, and low water levels occur in the fall or early winter. Water from the Mississippi alluvial deposits, Cockfield Formation, and Memphis Sand is a calcium bicarbonate type and is generally of good quality. Undesirable parameters from the standpoint of use are hardness and concentrations of dissolved iron and dissolved solids. The Fort Pillow Sand, as yet untapped, has potential to yield a sodium bicarbonate type of water of somewhat better quality than is available from the shallow aquifers. Estimated values of transmissivity from single-well pumping tests are highest for the Mississippi alluvial deposits and lowest for the Cockfield. Several north-northeast and west-northwest trending faults cross the country.
