Water Resources Data for Minnesota, 1971

Water Resources Data for Minnesota, 1971

1973

Water resources data for the 1971 water year for Minnesota 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 and ground-water, are given in this report. Records for a few pertinent gaging and water-quality stations and selected data on chemical quality of ground water in bordering States are also included. The records were collected and computed by the Water Resources Division of the U. S. Geological Survey under the direction of Charles R. Collier, district chief. Hydrologic data in this report are collected by the U. S. Geological Survey and cooperating State and Federal agencies in Minnesota. The data are part of the National Water Data System. Through September 30, I960, the records of discharge and stage of streams and contents and stage of lakes or reservoirs were published in an annual series of U. S. Geological Survey water-supply papers entitled, "Surface Water Supply of the United States." Beginning with the 1961 water year, streamflow records and related data have been released by the Geological Survey in annual reports on a State-boundary basis. Distribution of these reports is limited; they are designed primarily for rapid release of data shortly after the end of the water year to meet local needs. The streamflow records for 1961-65 are also published in a Geological Survey water-supply paper series entitled, "Surface Water Supply of the United States 1961-65." There will be a similar series of water-supply papers for the water years 1966-70. The Geological Survey has published records of chemical quality, suspended sediment, and water temperatures since 19^1 in an annual series of water-supply papers entitled, "Quality of Surface Waters of the United States." Beginning with the 196U water year, water-quality records also have been released on a State-boundary basis in conjunction with streamflow records or in a separate volume.
