Index of surface-water records, part 3, Ohio River basin, to September 30, 1948
This report summarizes ground-water-quality data, for Wisconsin, stored in the U.S. Geological Survey 's computer system (WATSTORE). The summary includes water-quality data for 2,443 wells which tap one of the State 's three major aquifers (sand and gravel, Silurian dolomite, and sandstone). Data for dissolved solids, hardness, alkalinity, calcium, magnesium, sodium, potassium, iron, manganese, sulfate, chloride, fluoride, and nitrate are summarized by aquifer and by county, and locations of wells where data are available are shown for each aquifer. Calcium, magnestium, and bicarbonate (the principal component of alkalinity) are the major dissolved constituents present in Wisconsin 's ground water. High iron concentrations and hardness cause ground-water-quality problems in much of the State. Statewide summaries of trace constituent (selected trace metals, arsenic, boron, and organic carbon) concentrations show that they impair water quality in only a few isolated wells. A bibliography of published reports that describe or summarize various aspects of ground-water quality in Wisconsin is included. (USGS)
Results of pumping tests on artesian wells in the Milwaukee - Waukesha area, Wisconsin
As a result of a bill passed by the Wisconsin State Legislature in 1945, ground-water investigations in Wisconsin have been under way since February 1946 under the terms of an agreement between the U. S. Geological Survey and the University of Wisconsin. Pumping tests on wells that yield water from the Ordovician and Cambrian sandstones underlying the Milwaukee-Waukesha area have been made as a part a larger regional investigation. The purpose of the tests has been to determine the water-bearing characteristics of the aquifer. These characteristics, the coefficients of transmissibility and storage, are used to determine the effect on water levels caused by changes in the rate of withdrawal from the aquifer. Average coefficients of transmissibility and storage determined from the results of 47 pumping tests at five different locations are 23,800 gallons a day per foot, and 0.00039, respectively. The amount of drawdown in the water level at any point caused by pumping a well for a given length of time may be computed by the nonequilibrium formula, using the coefficients and correcting for the effects of boundaries and of any changes in the character of the aquifer. Further study of the geology is needed to determine the location of the recharge area, the location of possible boundaries, and changes in the character of the aquifer. Collection of water-level and pumpage data is continuing and will serve as a check of the computations using the coefficients of transmissibility and storage.
Stream flow, suspended, and dissolved matter in streams on and near soil conservation project, La Crosse, WI
Measurements of stream flow and movement of suspended natter have been obtained at stations on the La Crosse project as indicated below: Little La Crosse River near Leon, Wis. Drainage area 77.1 square miles. The station is in sec. 3, T. 16 N., R. 4 W., 2 miles northwest of Leon, Monroe County; established March 14, 1934; suspended matter determined from April 1, 1934. Coon Creek at Coon Valley, Wis. Drainage area 77.2 square miles. The station is in sec. 7, T. 14 N., R. 5 W., in the village of Coon Valley, Vernon County; established March 16, 1934; suspended matter determined from April 6, 1934. Coon Creek near Stoddard, Wis. Drainage area 115 square miles. The station is in sec. 25, T. 14 N., R. 7 W., 3 1/4 miles east of Stoddard, Vernon County; established March 28, 1934; suspended matter determined from April 6, 1934.

The Delavan lobe of the Lake Michigan glacier of the Wisconsin stage of glaciation and associated phenomena
The purpose of this paper is to throw, if possible, some further light on the relations which existed during the later stages of the Glacial epoch between the glaciers of southeastern Wisconsin, which have been so ably discussed by Dr. T.C. Chamberlin and other writers in various publications, and the glaciers of Illinois, which have received such exhaustive treatment by Mr. Frank Leverett in his recent monograph on the Illinois glacial lobe.
Geology of Wisconsin: Survey of 1873-1879, Volume I
The leading purpose df this volume was determined by the following enactment, being section 1, chapter 121, of the Laws of 1876. " The people of the State of Wisconsin, represented in Senate and Assembly, do enact as follows: Section 1. That in the preparation of his final report, the chief geologist be, and he is hereby authorized to collate the general geology and the leading facts and principles relating to the material resources of the State, together with practical suggestions as to the methods of detecting and utilizing the same, so as to constitute the material for a volume suited to the wants of explorers, miners, land owners, and manufacturers, who use crude native products, and to the needs of the schools of the State, and the masses of intelligent people who are not familiar with the principles of geology; said volume to be written in clear, plain language, with explanations of technical terms, and to be properly illustrated with maps and diagrams, and to be so arranged as to constitute a key to the more perfect understanding of the whole report." To subserve the purposes thus legally defined, the volume will be found to consist of three distinct portions; Part I, embracing the General Geology of the State, with explanatory matter; Part II, consisting of lists of the minerals, rocks and life-products of the State, with descriptions and auxiliary discussions; and Part III, embracing industrial descriptions and practical suggestions with reference to the leading natural resources of the State.
Geology of Wisconsin: Survey of 1873-1879, Volume IV
In the preface of the preceding volumes, sufficient explanation has been made of most matters requiring consideration in such connection. For reasons explained in the preface of Vol. III, and for others that have arisen since, the earlier portions of this volume have rested in type, awaiting the completion of the remainder, for a length of time much to be regretted. Consideration of this fact is due to the authors of Parts I, II and III. The atlas accompanying this volume includes, besides those relating to its subject matter, the general maps that more properly belong with Vol. I, with which no atlas will be issued. They are here included for economy and convenience of distribution. The maps accompanying Vols. II, III and IV are intended to be combined to form a single atlas. If bound in folio, as planned, it will be reduced to a convenient size.
