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

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

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

Concentrations of people in urban areas intensify water problems such as flooding and pollution, but these deleterious effects on water resources can be minimized or corrected by comprehensive planning and management. Such planning of the water resources of an urban area must be based on adequate hydrologic data. Through the use of a matrix, urban water problems can be evaluated and availability o

Stratified fluvial sediments occur within the glacial drift at many places in the Mesabi Iron Range area. These sediments, which are important aquifers, occur extensively between the three main till units. The thickest and most extensive aquifer consists of glaciofluvial sediments that lie between the surficial till and the middle till unit, the bouldery till. Thickness of the glaciofluvial sedime

The Tri-County region, consisting of Clinton, Eaton, and Ingham Counties, is an area of 1,697 square miles in Michigan's Lower Peninsula and has as its hub the Lansing metropolitan area. The land surface ranges in altitude from about 700 to about 1,000 feet. The region receives an average of about 31 inches of precipitation each year. The population is nearing 400,000 and by 1990 will be near 600,
