Draft-storage-frequency relations, which show the storage required for a reservoir to furnish a specified withdrawal or draft are regionalized for four zones in the State, using the mean annual flow of the streams as an index. The differences between the zones primarily reflect differences in the variability of stream flow.To assure the available draft will fall below 75 percent of the mean annual

The Indiana Dunes National Lakeshore is underlain by unconsolidated lake and glacial deposits which have been divided into three units. Unit 1 is comprised mostly of sand and, in the western part of the National Lakeshore, is capable of yielding more than 500 gallons per minute (32 litres per second) to properly constructed wells. Unit 2, a silt till below unit 1, has little potential as a source

Lakes are bodies of water formed in depressions on the earth's surface, and as such, act as depositories for a variety of chemical and biological materials. The study of lakes has become increasingly prevalent in recent years. Lakes are a valuable resource, and their multiple uses have made them susceptible to water-quality problems such as algal blooms, sediment deposition and fish kills. These p

This report presents low-flow characteristics at six sites on streams in the Eau Claire River basin near Antigo, Wis., where applications for irrigation permits were made. The low-flow characteristics presented are the annual minimum 7-day mean flows at the 2-year recurrence interval and 10-year recurrence interval. A seepage run made October 10, 1974, showed a substantial gain in discharge from s

This report presents a computer simulation program that was used by Waddell and Bolke (1973) to predict the salt balance between the north and south parts of Great Salt Lake, Utah, for either existing or modified culvert openings (fig. 1). The development of the program, its accuracy and limitations, are described in the above report, which was prepared as part of a study conducted by the U.S. Geo

This statement is a response to questions raised by personnel of the U.S. Forest Service, Lakeview, Oregon, with respect to the possible effects on Lake Abert and its basin if the propos ed Coffeepot Reservoir is built on Chewaucan River. The responses are keyed to paragraphs in a letter of inquiry but are self-explanatory without reference to that letter.

U.S. Air Force Launch Control Facility 0-0 is located about 3.6 miles (5.6 kilometres) north of Cooperstown, Griggs County, North Dakota.  Test drilling indicates that a glacial-drift aquifer located within about 0.2 mile (0.3 kilometre) of the site will supply 2 to 3 gallons per minute (0.13 to 0.19 litre per second) of acceptable quality water for the facility.

The Montezuma Creek-Aneth area is in the northeastern part of the Navajo Indian Reservation in southeastern Utah. It is a semiarid area along the San Juan River near the communities of Montezuma Creek and Aneth. Within the Blanding Basin, geologic formations exposed are of Jurassic and Quaternary age. The rock strata are nearly horizontal, dipping gently northeastward. Wells derive small quantitie

Unconsolidated deposits of sand, silt, clay, and gravel compose the principal aquifer in Greeley and Wichita Counties. The deposits are as much as 300 feet (91 m) 2/ thick, of which as much as 145 feet (44 m) is saturated.In 1972, there were about 1,040 large-capacity wells--yielding 100 gallons per minute (6.3 1/s) or more--in the counties, mostly for irrigation supplies. The wells yield as much

On March 2, 1975, the U.S. Geological Survey completed a series of geophysical well logs in the Charleston Project Deep Core Hole No. 1 located at Latitude 32° 53.2 'N and Longitude 80° 21 . 5'W in Dorchester County near Charleston, South Carolina. The land surface is at an elevation of 5.4 m (18 ft) above mean sea level. The total depth of the test hole is 793 m (2,600 ft) and the geophysica

The city of Belcourt, Agency headquarters for the Turtle Mountain Indian Reservation, is located in northeastern Rolette County, north-central North Dakota.  At the request of the U.S. Public Health Service, the U.S. Geological Survey conducted a study in the vicinity of Belcourt to assist in location of a suitable water supply for the city.

Test drilling and geologic data indicate that there are two potential aquifers in the Belcourt, N. Dak. area capable of supplying a sufficient quantity of ground water for the city of Belcourt.  The Fox Hills aquifer, located about 3 miles (4.8 kilometres) west of Belcourt, could yield a sufficient quantity, as much as 500,000 gallons per day (1,900 cubic metres per day), of ground water for Belco
