Water-level measurements were made in 122 wells in January 1977. Changes in water levels from January 1976 to January 1977 ranged from a rise of 10.0 feet (3.0 meters) to a decline of 8.6 feet (2.6 meters) both of which occurred in Costilla County. Measurements for the three preceding winters...

Water-level measurements made in more than 465 wells in March 1977 in the lower Arkansas River valley of southeastern Colorado are presented. Measurements for the preceding 4 years are included to serve as references illustrating declining or rising water levels. Changes in water levels from December 1975 to March 1977...

Ground water beneath the 6.6-square-mile Chehalis Indian Reservation, Wash., most of which lies on a flood plain, occurs in the alluvial and terrace sand and gravel deposits. Supplies available within the depth zone of water-level fluctuations are estimated to be between 20 and 60 times that being pumped at the...

Two test wells were drilled in the upper Satus Creek basin of the Yakima Indian Reservation, Washington, using the air-rotary method. At site 1 the well penetrated a young basalt and 175 feet of the Yakima Basalt, and at site 2 the well penetrated the young basalt. The well at...

Hydraulic and chemical data were collected through a monitoring program conducted by the U.S. Geological Survey at an industrial liquid-waste injection site 6 mi southwest of Milton, Fla., in Santa Rosa County. The injection system is described. Data include injection rates, volumes, and pressures; water-level data at three monitor wells...

Merced is in the northeastern part of the San Joaquin Valley, California. The fresh-ground-water basin is about 1,200 feet thick. Five aquifers are defined in the Merced area: (1) The Mehrten Formation (Miocene and Pliocene), (2) a confined aquifer , (3) an intermediate aquifer, (4) a shallow aquifer, and (5)...

Exploration models for podiform chromite in the Medford-Coos Bay quadrangles must consider the facts that (1) one deposit occurs for every 5 km 2 of ultramafic outcrop; similarly for a 5 km 3 volume, and (2) the average deposit has a tonnage of 206 tonnes, a volume of 8.9 m...

This report contains basic data on water-level measurements in observation wells in western Kansas. Most of the measurements were made in January 1977; a few were made in December 1976 and in February 1977. The measurements were made in mid-winter when pumping was minimal and water levels had recovered from...

In 1974 the total pumpage for Lee County, Fla., municipal supplies reached 5,700 Mgal (million gallons annually), an increase of 54 percent over 1970 levels. Pumpage from individual sources included: Caloosahatchee River, 1,312 Mgal; water-table aquifer, 2,171 Mgal; the water-bearing zone in the Tamiami Formation, 340 Mgal; the water-bearing zone...

During the 1975 water year, rainfall was about average at Page Field, Florida, and from 20-25 percent below average at Lehigh Acres and Sanibel Island. Water levels were monitored in 57 observation wells in Lee County, Florida. Of the 23 wells that tap the water-table aquifer, one record high and...

Recent mapping of late Tertiary and Quaternary deposits in the northeastern San Joaquin Valley has shown the need for clarification, revision, and subdivision of some of the previously mapped stratigraphic units. We propose a uniform nomenclature for deposits younger than the Mehrten Formation in this region. The Laguna Formation (late...

The concentration of inorganic nitrogen was measured in samples from 521 wells in the upper glacial and Magothy aquifers and from 46 streams in Nassau and Suffolk Counties during May 1971. The predominant form of dissolved nitrogen was nitrate. Nitrate concentrations (as N) in the upper glacial aquifer in both...

Extensive gravity highs and associated magnetic anomalies are present in or near seven major eastern North American earthquake areas as defined by Hadley and Devine (1974). The seven include the five largest of the eastern North American earthquake .centers. The immediate localities of the gravity anomalies are, however, relatively free...

The program described here was designed for calculating the nonlinear seismic response of a system of horizontal soil layers underlain by a semi-infinite elastic medium representing bedrock. Excitation is a vertically incident shear wave in the underlying medium. The nonlinear hysteretic behavior of the soil is represented by a model...

Flood information for the Big Creek basin in Linn County, Iowa, should be of use to those concerned with the design of bridges and other structures on the flood plains of the streams. Water-surface profiles for the flood of May 1974 are given for Big Creek and its major tributaries,...
