The water resources were studied within an area whose natural ground-water flow is largely towards the center of the metropolitan area. This area coincides with the extent of the Hinckley Sandstone aquifer. Thus, the general geohydrology of the area bounded by the extent of the Hinckley Sandstone (about 6,000 square miles) as it relates to the hydrology of the Minneapolis-St. Paul metropolitan are

The purpose of this report is to describe the physical environment, availability, characteristics, distribution, movement, and quailty of water in the Pecatonica-Sugar River basin.  In addition, water use and water problems are summarized to give an understanding of man's management of water within the basin.

This hydrologic atlas is part of a comprehensive study of the water resources of southeastern Michigan. The data presented provides information on (1) the physical features of the Clinton River and its tributaries, (2) the characteristics of streamflow, (3) the quality of ground and surface water, and (4) the availability of ground water. This atlas is one in a series on the river basins of southe

The purpose of this report is to describe the water resources of the Menominee-Oconto - Peshtigo River basin in Wisconsin in order to aid in planning future water management in the basin and in nearby areas. The physical setting, availability, distribution, movement, quality, and use of water are discussed. The report presents general information on the basin that was derived from data obtained fr

The purpose of this report is to describe the physical environment, availability, characteristics, distribution, movement, and quality of water in the lower Wisconsin River basin. In addition, water use and water problems are summarized to aid in water management within the basin. Detailed water studies will be necessary as the need for specific information increases. The lower Wisconsin River bas

The topography of the Kettle River watershed is formed primarily by glacial deposits that mantle the bedrock. The glacial deposits are generally less than 100 feet thick. Bedrock consists of several types and occasionally crops out at land surface. Topography ranges from gently rolling to steeply undulating. About 1,060 square miles is drained by the Kettle River and its tributaries, and about 510

Reaeration coefficients (k2), which are rate constants for the process of oxygen absorption from the atmosphere, have been computed for Michigan's streams using an equation developed by Bennett and Rathbun (1972). Mean velocity and mean depth data, which are necessary for the computation, have been extracted from discharge measurements made at gaging stations throughout the State. The computed k2

Isle Royale was overridden by glacial ice during each of the four major glaciations of the Pleistocene Epoch, and each successive glaciation essentially obliterated all direct evidence of preceding glaciations on the island. In the waning phase of the last major glaciation, the Wisconsin Glaciation, the frontal ice margin retreated northward from at least the greater part of the Lake Superior basi

Glacial deposits in the Mesabi-Vermilion Iron Range area consist of four major till units and associated glaciofluvial sediments. Particle-size data and pebble, heavy-mineral, clay-mineral, and percentage-soluble content were used in addition to field description of color and texture to describe and correlate the drift units. The lowermost till unit, basal till, occurs in only a small number of mi
