Water resources data for the 1974 water year for Louisiana including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, 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 355 gaging stations of which 74 are streamflow discharge stations, 8 are stage only streamflow stations, and 11 are reservoir or lake stations; also are included records for 110 flood-profile partial-record stations, 83 crest-stage partial-record stations, and 69 miscellaneous sites Locations of continuous-record gaging stations are shown in figure 1 and locations of crest-stage partial-record stations are shown in figure 2. In Part 2, water-quality data on chemical, physical, and biological characteristics of surface water were collected from designated sampling sites at predetermined intervals such as once daily, weekly, monthly, or less frequently, and at some sites data were recorded on punched paper tape at 15- or 60-minute intervals. Records are given for sampling stations of which 12 are continuous-record stations, 50 are partial-record stations, and 103 are miscellaneous sites. Locations of water-quality stations are shown in figure 3. A few pertinent stations in 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 Albert N. Cameron, 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 Louisiana.
