Water resources data for the 1972 water year for Missouri including records of streamflow or lake storage at gaging stations, partial-record stations, and selected springs, and records of water-quality data on the chemical and physical characteristics of surface and ground water, are given in this report. In Part 1, records are included for 157 gaging stations of which 150 are streamflow discharge stations, and 7 are lake stations; also are included records for 104 crest-stage partial-record stations. Locations of gaging stations are shown in Figure 1. In Part 2, data on the quality of surface water (chemical, temperature, and sediment) were collected from designated sampling sites at predetermined intervals such as weekly, monthly, or less frequently, and at some sites data were recorded on punched paper tape at 30-, or 60-minute intervals. Records are given for 84 sampling stations of which 25 are partial-record stations and 5 are miscellaneous sites. Locations of water-quality stations are shown in Figure 2. A few pertinent stations (not included above) 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 Anthony Homyk, district chief. These data represent that portion of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies in Missouri.
