From abstract: Detailed knowledge of the geology of the pre-Cambrian rocks of the Lake Superior region has been greatly augmented since the publication of Monograph 52 by the United States Geological Survey in 1911. The authors have attempted in the present report to assemble as much of this new information as possible, and to give the reader a birdseye view of the geology as seen in the light of all studies made there up to the present time. Detailed descriptions are not presented, and the emphasis is placed upon the major problems of correlation. A revised map of the region, with cross sections, accompanies the report, bringing up to date a knowledge of the areal geology of the region, which otherwise could be gained only by consulting some 150 maps contained in almost as many separate local reports, many of which are unpublished.

Purpose and scope: The Eau Claire Quadrangle, Wisconsin and Minnesota, was evaluated to identify geologic units and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. All geologic environments to a depth of 1500 m (5,000 ft) were evaluated by means of surface investigations and available subsurface data. Each environment was categorized as favorable, unfavorable, or unevaluated for uranium deposits based on recognition criteria contained in the study of significant uranium districts worldwide (Mickle and Mathews, eds., 1978). Evaluation of the Eau Claire Quadrangle was conducted by Golder Associates, Inc., under subcontract to Bendix Field Engineering Corporation (BFEC), for the National Uranium Resource Evaluation (NURE) program, managed by the Grand Junction Office of the U.S. Department of Energy (DOE). The evaluation program began February 1, 1978, and ended February 1, 1980. Time spent by Golder personnel on literature search, field work, evaluation of data, and preparation of the final report totaled approximately 3.5 man-years.

From abstract: Results of a reconnaissance geochemical survey of the Iron Mountain Quadrangle, Michigan; Wisconsin are reported. Field and laboratory data are presented for 479 groundwater samples, 369 stream sediment samples, and 389 stream water samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

From introduction: This study was begun in 1967 in cooperation with the Wisconsin Department of natural Resources (DNR)--its purpose was to evaluate the effects of construction of a reservoir and a floodwater-retention structure on the hydrologic system and water quality in a small basin in southwestern Wisconsin. In 1968, Federal research funds were obtained to provide for more detailed study of water quality and to extend the scope of the study to include aquatic biota.

From abstract: "This study was made to identify the best predictive equations for a stream's reareation-rate coefficient. Reaeration-rate information is needed in dissolved-oxygen modeling work, but an actual tracer measurement is not always possible."

From introduction: The purpose of this report is to present the magnitude and types of nonpoint discharges that affect the water quality of Steiner Branch.

This report describes the use of "radioactive and modified tracer techniques . . . to measure the re-aeration coefficients of two reaches each of Black Earth Creek and the Madison Effluent Channel near Madison, Wisconsin." It contains maps and graphs.

Abstract: The primary effect of a floodwater-retarding structure (FRS) on the flow of Trout Creek, Wisconsin, is attenuation of flood peaks. Reduction of flood peaks ranged from 58 to 91 percent during the study period, 1975 to 1979. An inverse relationship exists between sediment concentration and outflow from the FRS during floods. Most sediment stored in the flood pool during floods is released from the reservoir during subsequent reduced discharge. Sediment-trapping efficiency of the FRS was 7 percent during the 4-year study. The bankfull capacity of the channel was reduced from 154 cubic feet per second upstream from the FRS to 65 cubic feet per second downstream. Mean bankfull depth downstream from the FRS has adjusted to a value 45 percent less than upstream from the structure due to the sedimentation of materials transported from the FRS during reduced flows. The FRS was not found to have any significant adverse effect on the arthropod fauna or trout reproduction in Trout Creek from 1975 to 1979. During 1960-1979, winter floods seem to have had the greatest adverse effect on the survival of brown trout eggs and sac fry.

From explanation: The data used to make this map were taken from many sources and include water levels from different years and seasons. An effort was made to use data that represented average water levels.

From abstract: The purpose of this report is to present low-flow characteristics of Wisconsin streams at sewage-treatment and industrial plants. The low-flow characteristics are needed to implement water-quality standards for all surface waters of the State. Water-quality standards in Wisconsin are based on the annual minimum 7-day mean flow below which the flow will fall on the average of once in 10 years.

From abstract: "Various changes in the management practices for the Winnebago pool to protect wetlands adjacent to the pool and to assure adequate streamflow downstream from the pool have been proposed. The effects of three such changes were estimated by using a digital reservoir model to simulate daily stage and discharge."

From abstract: This report summarizes the uses of water in Wisconsin for 1979, except aesthetics, navigation, and recreational use.

From abstract: Sedimentary rocks of Cambrian and Ordovician age form a major aquifer system in most of Wisconsin and Iowa, northern Illinois, northwestern Indiana, southeastern Minnesota, and northern Missouri. Many metropolitan areas depend on the aquifer for all or part of their water supplies. Declines in potentiometric head have been large in the most heavily pumped areas, most notably Chicago, Milwaukee-Waukesha, Minneapolis-St. Paul, and Des Moines.

From introduction: The purpose of this report is to describe low-flow characteristics of streams in the Trempealeau-Black River basin where streamflow data have been collected and to present equations useful for estimating low-flow characteristics at ungaged sites.

From introduction: This report presents practical and useful sediment-yield information for Wisconsin. Measured and estimated sediment yields are supplemented by information on suspended-sediment concentration and particle size of suspended and bed material for 84 sites in the State. To expand the usefulness of these data, an additional section in the report presents a method to estimate or predict sediment yields in ungaged streams.

From introduction: This report describes the design and implementation of a prototype water resources information system for the Fox-Wolf River basin...This report also describes the use of the Fox-Wolf information system for an assessment of selected hydrologic conditions in the basin.

This report summarizes the mercury studies, and has two main objectives. First to summarize the findings of biogeochemical investigations in the Devils Lake watershed during 2002, 2003, and 2004 and compare them to findings for other lakes. The second objective is to compile and tabulate the large amount of mercury data that are collected so that they will be usefule to the Tribe in future studies.
