Abstract

Water resources data for the 2002 water year for Arkansas consist of records of discharge and water quality (physical measurements and chemical concentrations) of streams, water quality of lakes, and groundwater levels and ground-water quality. Data from selected sites in Missouri and Oklahoma also are included. This report contains daily discharge records for 108 surface-water gaging stations and 87 peak-discharge partial-record stations, water-quality data for 65 surface-water stations and 5 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.


Note: Historically, this report has been published as a paper report. Beginning with the 2002 water year report, these reports will be available from the World Wide Web at http://ar.water.usgs.gov.
