Water resources data for the 1974 water year for Mississippi including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, special information on the flood in south-central Mississippi in April, and records of water-quality data on the chemical and physical characteristics of surface water, are given in this report. In Part 1, records are included for 79 gaging stations of which 75 are streamflow discharge stations, and 4 are reservoir or lake stations; also are included records for 11 low-flow partial-record stations, 136 crest-stage partial-record stations, and 149 miscellaneous sites. Locations of continuous-record gaging stations are shown in figure 1 and locations of partial-record stations are shown in figure 2. In Part 2, water-quality data on chemical, physical, and biological characteristics of surface water are included for designated sampling sites at which samples were obtained at predetermined intervals such as daily, weekly, monthly, or less frequently. Records are given for 70 sampling stations of which 32 are continuous-record stations, 26 are partial-record stations, and 12 are miscellaneous sites. Locations of water-quality stations are shown in figure 1. A few pertinent stations (not included above) furnished by bordering States are also included in this report. The records were collected and computed by the Water Resources Division of the U.S. Geological Survey under the direction of L. E. Carroon, district chief. 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 Mississippi.
