The per capita use of water in the Pittsburgh area in 1951 was 2, 000 gallons per day fgpd) or twice the per capita use in Pennsylvania as a whole. An average of about 3, 040 million gallons of water was withdrawn from the streams and from the ground each day. Of this amount, nearly 190 million gallons per day (mgd), or 6 percent, was for domestic public water supply. Industry, including public ut

Record-breaking floods occurred June 27, 28, 1954, in the Devils and lower Pecos Rivers and in some tributaries to those streams, caused by heavy rainfall of June 26-28. At the time of the flood the geological Survey was not operating a gaging station in the Devils River basin or in the Pecos river basin below Girvin. Continuous records of the flow of Devils River were obtained by the Geological S

Forty-four records of reservoir trap efficiency and the factors affecting trap efficiency are analyzed. The capacity-inflow (C/I) ratio is found to offer a much closer correlation with trap efficiency than the capacity-watershed (C/W) ratio heretofore widely used. It appears likely from the cases studied that accurate timing of venting or sluicing operations to intercept gravity underflows can tre

In a balanced study of water pollution or water utilization a thorough chemical and physical examination is essential. This provides a basis for evaluation of stream conditions, their effects and remedies. Such information is of value to the general public who are interested in clean water and in recreation, hunting, fishing, and wildlife; to the chemist, engineer, hydrologist, and industrialist w

The drainage area of the Great Lakes is equal to nearly one-tenth of the entire area of the United States; 58 percent of this area lies within the United States. The information in Table 3 affords a ready comparison of the land and water areas involved in the United States and Canada in the Great Lakes system. It will be noted that the total water surface is almost one-third of the entire drainage

This volume of the History of the Water Resources Branch of the United States Geological Survey by Robert Follansbee covers the period from July 1, 1919, to June 30, 1928. In conformity with the practice followed in the first volume of the "History" Mr. Follansbee has named this volume "Years of Increasing Cooperation."
