Abstract

Detailed ground-water-use information from 1880 to 1980 has been collected and analyzed for the Twin Cities metropolitan area. Interpretation of historic water-use data was required to help water-resource planners and managers assess future trends in water use. Methods were developed to collect, evaluate, store, and retrieve information from all local, State, and Federal agencies ' records and publications. A computerized water-use data base was constructed to facilitate generation of statistics on water-use trends and to store and retrieve data. Ground-water use was analyzed by use category and aquifer and several trends were observed. Eighty percent of ground water currently withdrawn is from wells in the Prairie due Chien-Jordan aquifer. Ground-water use increased from 1880 until the early 1970 's and then declined slightly in the late 1970's. Industrial use in particular declined during the 1970 's as a result of conservation that was prompted by increased sewage-treatment and energy costs. The intensity of pumping had decreased within the St. Paul and Minneapolis city limits and increased outside the city limits. The seasonal variability of ground-water use became more pronounced as the percentage of water used for irrigation and air conditioning increased. (USGS)
