Water resources of the Mississippi Headwaters Watershed, North-central Minnesota

The Mississippi Headwaters watershed is a 7,608 square mile area in north-central Minnesota which includes all land drained by the Mississippi River above the Crow Wing River. From its source in Lake Itasca, 1,460 feet above mean sea level, the Mississippi River follows a semicircular 376 mile course to where it leaves the watershed at an altitude of 1,150 feet. The origin of the river is in glaci

Water resources of Wisconsin, Fox-Wolf River basin

PURPOSE AND SCOPE The purposes of this report are to (1) describe the geohydrology of the basin, (2) describe and relate the surface- and ground-water systems, (3) discuss existing and possible future water problems in the basin, and (4) to suggest means of possible solutions. The scope of the study was to interpret and relate streamflow, climatic, geologic, and ground-water information. Because o

Geochemistry and ground-water movement in northwestern Minnesota

The relation between water quality and water movement within the ground-water reservoir may be better understood if studies of flow systems are used in conjunction with hydrochemical methods. Within small watersheds, local, intermediate, and regional flow systems may develop, depending upon the shape, the relief, and the thickness of the ground-water reservoir. Lateral and vertical variations of w
