The ground water in Lyon County and elsewhere in southwestern Minnesota is generally hard and low in chloride. It is the purpose of this report to describe briefly the occurrence in Lyon County of waters of low hardness and of high chloride content. The waters are found largely in Cretaceous sandstone. The data were collected in conjunction with a countywide study of the geology and groundwater re

The floods of May 1959 in the Au Gres and Rifle River basins, Michigan, resulted from heavy rainfall during the night of May 19-20. Peak unit discharges for small drainage areas (less than about 15 square miles) were the highest ever measured in the Lower Peninsula of Michigan, and for very small areas (about one square mile) were of the same order of magnitude as those for the record Ontonagon Ri

A few Upper Precambrian (Keweenawan) diabase dikes and two remnants of sandstone and dolomite of early Paleozoic age ar

The visual-tube method for sedimentation analysis of sands was developed as a part of the general investigation titled "A Study of Methods Used in Measurement and Analysis of Sediment Loads in Streams." The method is one answer to the need for a simple, rapid, and inexpensive means of determining the sedimentation-size frequency analysis of sand samples containing particles less than one millimete

Outagamie County is in east-central Wisconsin. It has no serious groundwater problem at present, but the county is important as a recharge area for the principal aquifers supplying water to Brown County and industrial Green Bay to the east. The county is covered by glacial drift and lake deposits of the Wisconsin stage of glaciation. In the northwestern quarter of the county these deposits rest up
