A prairie pothole is a depression in the prau1e, capable of storing water, that is the result of glacial processes. Years ago, there were many hundreds of thousands of prairie potholes in the North-Central United States, but large numbers of them have been drained for agricultural use. This report is limited to studies of prairie potholes in the eastern part of the glaciated northern...

Measurements of specific conductance provide an adequate indication of the average salinity of surface waters in natural ponds and lakes of the northern .prairie region. Yearly and seasonal variations in specific conductance were much greater in brackish and subsaline wetlands than in fresh-water areas. The principal vegetational types. Land-use practices of varying brackish to saline...

Prairie potholes (sloughs) are water-holding depressions of glacial origin in the prairies of the Northern United States and southern Canada. Water is supplied to the potholes by precipitation on the water surface, basin runoff, and seepage inflow of ground water. Depleticn of pothole water results from evapotranspiration, overflow, and seepage outflow. Since potholes generally do not...

The purpose of this investigation is to provide information about the ground-water resources in Benson and Pierce Counties that is sufficient for planning the safe and intelligent development of water supplies for irrigation, domestic, stock, industrial, and municipal purposes. The investigation is part of a statewide program to determine the location and extent of ground-water aquifers...

Since the dawn of civilization waterfront land has been an irresistible attraction to man. Throughout history he has sought out locations fronting on oceans, rivers, and lakes. Originally sought for proximity .to water supply and transportation, such locations are now sought more for their esthetic qualities and for recreation. Usable natural waterfront property is limited, however, and...

An investigation of the geology and ground-water resources of the Pine Ridge Indian Reservation, South Dakota, was made at the request of the Bureau of Indian Affairs as part of the U.S. Department of the Interior's program for the development of the Missouri River basin. The area of investigation (about 3,930 square miles) includes all the land within the original boundaries of the...

Studies of infrared imagery obtained from aircraft at 305- to 1,524- meter altitudes indicate the feasibility of monitoring thermal changes attributable to the operation of thermal-electric plants and storage reservoirs, as well as natural phenomena such as tributary inflow and ground-water seeps, in large rivers. No identifiable sources of ground-water inflow below t he surface of the...

This investigation is part of a statewide program to determine the location, extent, and nature of the ground-water reservoirs (aquifers); to evaluate the occurrence and movement of ground water within these aquifers, including the sources and areas of recharge and discharge; to estimate the potential yields of wells tapping the major aquifers; and to determine the chemical quality of...

Subsurface waste disposal by means of wells is the practice of using drilled wells to inject unwanted substances into underground rock formations. The use of wells for this purpose is not a new idea. As long ago as the end of the last century, it was common practice to drill wells for the express purpose of draining swamps and small lakes to reclaim the land for agricultural purposes. A...
