Temperature is probably the most important, but least discussed, parameter in determining water quality. The purpose of this report is to present the average or most probable temperatures of surface waters in the conterminous United States and to cite factors that affect and are affected by water temperature. Temperature is related, usually directly, to all the chemical, physical, and biological p

Runoff is that part of precipitation that appears as a flow of water in surface streams. As a source of water for modern society, it constitutes one of our basic renewable resources. This map of average annual runoff portrays the latest information on the geographic distribution of the average runoff of surface streams.

This collection of 44 short papers is the third published chapter of "Geological Survey Research 1966." The papers report on scientific and .economic results of current work by members of the Conservation, Geologic, and Water Resources Divisions of the U.S. Geological Survey.

This report describes the availability, quantity, quality, variability, and cost of development of the ground-water resources in the Juniata River basin, one of the larger sub-basins of the Susquehanna River basin. The report has been prepared for and under specifications established by the Corps of Engineers, U. S. Army, and the Public Health Service, Department of Health, Education, and Welfare.

A stream-quality reconnaissance at 318 locations in May 1965 offered the first opportunity for a contemporaneous regional collection and appraisal of water-quality data in Appalachia. The results provide a means of regional comparison of the influence of coal-mine drainage on stream quality at approximately median streamflow. The results disclose that the chemical quality of the water at nearly 20
