The United States has about 250 fresh-water lakes that are known to have surface areas of 10 square miles or more. Nearly 100 of these are in Alaska, and 100 in Minnesota, Wisconsin, Michigan, New York,, and Maine. Thirty-four fresh-water lakes, exclusive of the Great Lakes, are known to have maximum depths of 250 feet or more. Twenty of these are in Alaska, and Alaska undoubtedly has more lakes o

Ground water in the United States has emerged from a quantitatively minor (though incalculably valuable) water source, whose chief role was in the settlement of primitive areas, to a major source now accounting for one-fifth to one-sixth of the Nation's total withdrawal requirements for water. With the growth in ground-water withdrawals is an accompanying growth in the realization that large-scale

The floods of January-February 1959 in Indiana exceeded those previously known on many streams in the southeastern portion of the State in January and on several streams in the Wabash Valley during February. At least 3 lives were lost, more than 2,000 people were evacuated, and dozens of bridges were washed away. Heavy rains falling on frozen ground caused unusually high runoff. Rainfall was great

The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from activities of man. Some of the processes of solution or precipitation of minerals can be closely evaluated by

Indiana's lakes are a valuable resource for both recreational use and their industrial potential. Some lakes are used for water supply. The natural lakes are glacial in origin and are most concentrated in northeastern Indiana. Many of the lakes were drained by the early settlers. The natural processes of sedimentation ad accumulation of organic deposits tend also to reduce the number and size of l

Water used in the Indianapolis area comes from two sources: the White River and tributary streams and the underground reservoirs formed by the underlying glacial drift and limestone. Surface-water sources provide about 60 mgd (million gallons per day) for public supply and an additional 300 mgd is used by private industries and is returned directly to the streams. About 60 mgd is taken from ground

Public water supplies are utilized extensively by industries for processing, cooling, and steam generation. The requirements as to quality of water for each industry are specific, therefore information on the quality or chemical character of the water supply is essential not only in the location of industrial plants but also is an aid in the manufacture and distribution of products. Data are given

The City of Evansville, Ind. has utilized the Ohio River as a source of municipal water supply for many years. The average daily pumpage for the city in 1950 was reported to be about 18.5 million gallons. Because of the extreme variability in the quality of the river water and the extensive treatment necessary, the city considered the possibility of developing a ground-water supply to supplement i

In January and February 1937 the Ohio and mid-Mississippi Rivers experienced floods which, over reaches many hundreds of miles in length, exceeded all previously recorded stages. When measured by the loss of life and property, extent of damage, and general disruption of human activities, these floods constituted a major catastrophe. The floods were caused by a succession of heavy rainstorms that b

In the summer of 1903 the late Richard B. Dole, chemist of the water-resources branch of the United States Geological Survey, began a systematic investigation of the composition of the river and lake waters of the United States. His plan, which developed gradually, was to have analyses made of the different waters in such a manner as to give the average composition of each one for an entire year.
