The Dakota sandstone underlies most of North Dakota and South Dakota and considerable parts of nearby States. In most of the area that it occupies it is covered with thick deposits of younger formations, chiefly shale, that confine the water in the sandstone under considerable pressure. Where the topography is favorable, as it is in the Ellendale-Jamestown area in southeastern North Dakota, wells

As a result of the need for basic data and the lack of a current and convenient summary concerning the surface-water resources of lown, a synoptic inventory has been prepared as a part of the present State-wide program which is made possible by State and Federal cooperative action. These hydrologic data are assembled in abbreviated form for the convenient* of the public and in order that a current

This report covers Angelina County, Texas, of which Lufkin is the county seat, and parts of Nacogdoches and other adjacent counties. The area is underlain by a series of sands, clays, and shales of Eocene age that dip, in general, southward at an angle a little greater than that of the land surface, which also slopes southward, thus creating favorable artesian conditions. The formations cropping o

Balmorhea is the center of a thriving farming community, the lands of which are irrigated with water derived chiefly from large springs but partly from the storm flow of Toyah Creek. The storm flow of the creek and a part of the winter flow of the springs is stored in a reservoir near Balmorhea and used later to supplement the flow of the springs. The present investigation was made to determine th

This paper summarizes the results of a detailed investigation by the U. S. Geological Survey in cooperation with the Kansas State Geological Survey, Kansas State Board of Health, and the City of Wichita. The geology of the area has been remapped, and several new formations have been established, including the Emma Creek formation of middle and upper Pliocene age, and a thick loess deposit. The hyd

Introduction: Water is a necessity of life. Accordingly, every person is deeply interested in the subject of water supply. He knows that he must have water to drink. He depends indirectly on water for all his food and clothing. He may want water in which to wash. Civilized man has learned also that water serves admirably for a large and ever enlarging list of uses that depend on its easy convertib
