    Bulletin No. 31. The Geology and Underground Waters of Southern Minnesota
    (Minnesota Geological Survey, 1944) Thiel, George A.
    The first reports on the water supplies of southern Minnesota were made late in the past century by my distinguished predecessor, Dr. N. H. Winchell, and his associates. The latest report before the present bulletin was by Professor C. W. Hall, Dr. O. E. Meinzer, and Mr. M. L. Fuller, and was issued in 1911. These two reports were excellent and included essentially all the data available at the time of their preparation. The supply of these reports was soon exhausted, and many requests for information on water supplies of the region were received at the office of the Minnesota Geological Survey from officers of municipalities, railroad companies, canning and packing plants, creamery operators, fanners, well drilling engineers, and from industrial plants. New data were steadily becoming available, chiefly by the sinking of new wells, and it soon became apparent that if the State Geological Survey were to answer these inquiries adequately it must obtain and utilize the information as it became available. Notwithstanding his other heavy university duties, Dr. George A. Thiel agreed to undertake the collection and correla tion of the increasing volume of well records. The results of his researches, together with water analyses and other data supplied by the State Board of Health and by the Division of Lands and Minerals of the State Department of Conservation, are presented herewith. References to papers treating the water supplies of southern Minnesota may be found in this report and also in Bulletin 30 of the Survey, issued in 1943.

    Bulletin No. 32, The Geology and Underground Waters of Northeastern Minnesota
    (Minnesota Geological Survey, 1947) Thiel, George A.
    In 1924 the Minnesota Geological Survey began the task of compiling up-to-date information on the underground waters of Minnesota. Dr. Ira S. Allison carried on much of the work for the northwestern portion of the state and prepared Bulletin 22, The Geology and Water Resources of Northwestern Minnesota, which was published in 1932. Shortly thereafter, Professor Thiel began the revision of the data for the southern half of Minnesota which had originally been discussed in the United States Geological Survey Water-Supply Paper 256 by C. W. Hall, O. E. Meinzer, and M. L. Fuller. Dr. Thiel's revision appeared as Minnesota Geological Survey Bulletin 31 in 1944. The present bulletin completes the series on the underground waters of Minnesota and makes available in published form data on the underground water resources of every county in the state. These bulletins cannot be considered final because water will continue to be developed as long as people inhabit the state. The Minnesota Geological Survey will therefore welcome cooperation in keeping up its file of data on underground waters and will be pleased to answer inquiries not covered by the published material. The state owes a debt to Professor Thiel for the very large amount of painstaking work which has gone into Bulletins 31 and 32. The three bulletins arc available from the University of Minnesota Press at a moderate price. Attention should also be called to the fact that all legal matters regarding underground, as well as surface waters, are by act of the legislature placed under the jurisdiction of the Department of Conservation.

    Educational Series 8. Using Ground-Water Data for Water Planning
    (Minnesota Geological Survey, 1987) Olsen, Bruce M.; Mohring, Eric H.; Bloomgren, Patricia A.
    Thoughtful and broad-based planning is the foundation for wise use and management of Minnesota's ground-water resources. Effective water planning must match a variety of resource questions with appropriate types of data. The ability to understand ground water is limited because ground water is an "unseen" resource. We must rely on information from single points, such as individual monitoring wells, to piece together the resource picture. Hundreds of thousands of single point observations about Minnesota's ground water have been generated by government and the private sector. These data must be arranged and maintained in storage and retrieval libraries if they are to be used efficiently to answer ground-water questions. Data, however, are merely the tools for decision-making; this cannot be overemphasized. Data arrangement showing ground-water conditions will affect how a water management question is perceived, as well as how accurately or completely it can be answered. Appropriately designed data bases are the best means to ensure that all available ground-water information is used to portray conditions realistically. This booklet is an introduction to the use of existing data systems and the integration and development of data management systems into water planning.
