The U.S. Geological Survey, in cooperation with local, State, and Federal agencies and organizations, obtains a large quantity of data pertaining to the water resources of Missouri each water year (October 1 to September 30). These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water resources of Missouri. To make these data readily available to interested parties outside the U.S. Geological Survey, the data are published annually in this report series, entitled "WATER RESOURCES DATA FOR MISSOURI." This volume contains records for water discharge at 107 gaging stations; stage and contents at 11 lakes and reservoirs; water level records for 58 ground-water monitoring wells; water quality at 43 sampling stations (including 2 lakes); and data for 13 crest-stage stations.
