In recent years, great emphasis has been placed on protection and conservation of water resources. In response to these needs, the U.S. Geological Survey established a monitoring network called NASQAN (National Stream Quality Accounting Network) in 1973. One of the objectives of NASQAN is to describe the areal variability in the quality of water in the nation's streams through analysis of data from this and other programs. With computerized statistical-analysis techniques available today, it is possible to analyze large quantities of data to aid in interpreting and in making decisions. The report has the following primary objectives: describe, on both a spatial and temporal basis, the stream-water quality throughout the study area upstream from the NASQAN site, Mississippi River at Nininger, Minnestoa; relate water-quality variability to general causes, such as selected basin characteristics, including land and water use; and assess how well water-quality data collected at Nininger represent the quality of water throughout the study area. In addressing the above objectives, the report first discusses the water quality in each subbasin, then examines the differences between subbasins, and then evaluates the representativeness of data collected at Nininger.
