Mississippi, Arkansas, and Tennessee Regional Aquifer Study

Ground-water data in the MATRAS area have been collected to characterize and determine ground-water levels and ground-water quality. Water-level data can be used to identify the directions of ground-water flow and to identify and evaluate local and regional trends as water levels fluctuate in response to natural and man-induced changes. Water-use data have been collected as part of the USGS National Water-Use program with data and national reports available on a five-year cycle.

Additional ground-water data for the counties in the MATRAS area can be retrieved through the USGS NWIS-WEB site for each of the three states; Mississippi, Arkansas, and Tennessee.

Water-Use Data

The U.S. Geological Survey has, since 1950, compiled data on water use throughout the United States. The national water-use reports are published on a 5-year cycle and are available on-line through the Water-Use reports page.

Selected water-use reports are included in the Water-Use Bibliography, by State, including the three MATRAS states; Mississippi, Arkansas, and Tennessee.

Water-use data by State and County can be retrieved from the National Water-Use program for:

1985 and 1990, 1995, and 2000
