This report outlines methods by which the magnitude and frequency of expected floods of any recurrence interval from 1.1 to 50 years can be determined at most points in the Colorado River basin.Composite frequency curves were drawn showing the relation of the mean annual flood to floods having recurrence intervals from 1.1 to 50 years. Other curves express the relation of the mean annual flood to

Increasing world activity in water-resources development has created an interest in techniques for conducting investigations in the field. In the United States, the Geological Survey has the responsibility for extensive and intensive hydrologic studies, and the Survey places considerable emphasis on discovering better ways to carry out its responsibility. For many years, the dominant interest in f

The Heart River drainage basin of southwestern North Dakota comprises an area of 3,365 square miles and lies within the Missouri Plateau of the Great Plains province. Streamflow of the Heart River and its tributaries during 1949-58 was directly proportional to .the drainage area. After the construction of Heart Butte Dam in 1949 and Dickinson Dam in 1950, the mean annual streamflow near Mandan was

The Aurora area is a glaciated upland of drift-mantled slopes, channels, swamps, and glacial-lake plains. It covers about 24 square miles of the eastern part of the Mesabi Iron Range in northeastern Minnesota. A deep narrow channel along the Embarrass River, the principal outlet of a former large glacial lake north of the Embarrass Mountains, lies partly within the area. The deposits in the report

Sustained flows of fresh water greater than 3,500, 4,400, and 5,300 cubic feet per second into the Delaware River estuary at Trenton, NJ assure low salinity at League Island, Eddystone, and Marcus Hook, respectively. When the discharge at Trenton is less than these critical values, salinity is very sensitive to change in discharge, so that a relatively small decrease in fresh-water discharge resul

Analyses of data collected from two small basins in northern Pennsylvania during the period May 1954 to September 1960 indicated that changes in land use and land treatment have affected suspended- sediment discharge from the basins. Extensive land use and land-treatment changes have taken place in the 12.2-square-mile Corey Creek study basin, whereas such changes in the 10.2-square-mile Elk Run b

This report summarizes the storage capacities and related data of reservoirs and controlled natural lakes for the contermimous United States, Alaska, Hawaii, and the Commonwealth of Puerto Rico. Data are given for all storage facilities having a usable capacity of 5,000 acre-feet or more and completed or under construction as of Jan 1, 1963.A descriptive list of reservoirs m the United States comp

Floqd records fo.r regular and partial-record gaging stations are contained in the following pages. Each listing contains the station number .and name, descriptive paragraphs pertaining to the station, qnd a listing of the flood peaks available through the 1965 water year. Peaks above a base as well as annual peaks are listed. These provide the data for a partial-duration flood-frequency curve. Mo

Flow-duration, annual low-flow, and annual high-flow tables through September 30, 1963, are given in this report for 110 stream-gaging stations in the Willamette and Sandy River basins. These tables summarize the basic data needed to define the streamflow characteristics at the gaging stations. The content of each of the three summary tables is described, and techniques for preparing flow-duration

A severe thunderstorm accompanied by much hail swept through southwest-central North Dakota on the afternoon of June 24.  Rainfall of up to 13 inches caused floods higher than any previously known in the area.  The isohyetal map (fig. 1) indicates the extent and magnitude of the storm. This map was derived from rainfall data at 20 U.S. Weather Bureau gages (4 recording), 26 Geological Survey gages
