The Water Resources Discipline of the U.S. Geological Survey, in cooperation with State, Federal, and other local governmental agencies, obtains a large amount of data pertaining to the water resources of Arkansas each year. These data, accumulated during many water years, constitute a valuable database for developing an improved understanding of the water resources of the State.
Water resources data reported for the 2003 water year for Arkansas consist of records of discharge and water quality (physical measurements and chemical concentrations) of streams, water quality of lakes, and ground-water levels and ground-water quality. Data from selected sites in Louisiana, Missouri and Oklahoma also are included. This report contains daily discharge records for 108 surface-water gaging stations, 76 peak-discharge partial-record stations, 9 stage-only stations, water-quality data for 73 surfacewater stations and 17 wells, and water levels for 15 observation wells. Additional water data were collected at various sites, not part of the systematic data-collection program, and are published as miscellaneous measurements.
