Water resources data for the 1984 water year consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; water levels and water quality of ground-water wells; and water quality of precipitation stations. This report contains records for water discharge at 85 gaging stations; stage at 23 gaging stations; stage and contents of 13 lakes and reservoirs; water quality at 31 gaging stations, 26 partial-record stations; water levels at 48 observation wells and water quality at 5 wells. Also included are data for 4 crest stage, 6 flood hydrograph partial-record stations, and 3 quality of precipitation stations. Location of these sites are shown on figures 4-8. Additional water data were collected at various sites, not involved in the systematic data-collection program, and are published as miscellaneous measurements and analyses. Discharge records for a few pertinent stations in bordering states are also included in this report. These data represent that part of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies in Alabama.
