This report splits the Superior Upland physiographic province of Minnesota into seven regions and concludes that the surficial geology is a result of glacial activity. This report includes several maps and tables.

From introduction: In this report, two programs have been developed for use in managing data derived from an aquifer thermal-energy storage (ATES) project being done by the University of Minnesota. Data are generated from temperature and pressure measuring devices that are read automatically by a datalogger. Up to 100 channels can be scanned every 10 seconds and recorded on magnetic tape or printed as paper output. Time period of up to several years of data may be represented on a single tape.

Abstract:Data were collected and summarized on the hydrology and hydrogeology of 949 lakes, 10 acres (4 hectares) or larger, in the Minneapolis-St. Paul metropolitan area, Minnesota. Eight tables totaling over 100 pages present data on location, depth, area, lake level, ecological and game-management classification, inflowing and outflowing streams, soils, bedrock type, water added to or take from lake, and reported lake-related problems. SYSTEM 2000, a generalized computer data-base management system, was used to organize the data and prepare the tables. SYSTEM 2000 provides powerful capabilities for future retrieval and analyses of the data. The data base is available to potential users so that questions not implicitly anticipated in the preparation of the published tables can be answered readily, and the user can retrieve data in tabular or other forms to meet his particular needs.
