Digitized Contours from Georeferenced Plate 1996 from "Louisiana Ground-Water Map No. 13: Hydrogeology and Potentiometric Surface of the Sparta Aquifer in Northern Louisiana, October 1996" (Brantly, Seanor, and McCoy 2002)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-12-01T00:00:00Z
This report describes the thickness and areal extent of the Sparta aquifer, identifies sands within the fresh-water extent of the aquifer, and presents data and a map that illustrate the generalized potentiometric surface (water levels) during October 1996. The report includes a detailed geophysical log, structure contour maps, hydrogeologic sections, and hydrographs of water levels in selected wells. The potentiometric surface-map can be used for determining direction of ground-water flow, hydraulic gradients, and the effects of withdrawals on the aquifer.
