Hydrogeologic and construction data obtained from 119 test holes, wells, and emplacement holes at the Nevada Test Site and vicinity (through December 1966) are tabulated. The availability of cuttings, cores, lithologic logs, geophysical logs, formation-water analyses, hydraulic test data, and detailed construction data for each hole, as well as references...

Studies of published and unpublished geologic, hydrologic, and chemical-quality data for ground and surface water in central Nevada, Tps. 1 to 21 N. and Rs. 41 to 57 E., Mount Diablo base and meridian, reveal the following information: Rocks exposed in central Nevada are of sedimentary and igneous origin and...

Approximately 1,400 feet of continuous core was taken .between 800-2,214 feet in depth from USBM/AEC Colorado core hole No. 2. The drill, site is located in the Piceance Creek basin, Rio Blanco County, Colorado. From ground surface the drill hole penetrated 1,120 feet of the Evacuation Creek Member and 1,094...

This report has been prepared at the request of the Kansas Water Resources Board under provisions of a cooperative agreement with the U.S. Geological Survey dated July 1, 1966, for water-resources investigations. The Kansas Water Resources Board has been advised of a recent serious degradation of the low-water channel of...

The disposition of radionuclides in and along the 380-mile reach of the Columbia River between the Hanford, Wash., Atomic Energy Commission reactors (the major radionuclide source) and the head of the estuary is a first step in understanding the environmental cycling and ultimate fate of the discharged radioactive materials. Preliminary...

Shock effects in quartz, plagioclase, biotite, amphibole, and some accessory minerals have been observed in rocks subjected to various degrees of meta morphism by meteoritic impact. The shock features described are unique; they are never observed in rocks from normal geologic environments. Such features are described:1) Multiple sets...

The scope of area1 investigations of water resources in New York has changed within the last 4 years. Prior 1962, most investigations covered only counties or smaller areas and were mainly restricted to ground‐water resources Since 1762, investigarions have covered largebasin (2,000‐4,000 square miles) with the purpose of defining total water resources so that basin‐wldc comprehensive plans for water development can be prepared. Ground water has been intensively...

The U.S. Soil Conservation Service is actively engaged in the installation of flood and soil erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found...

The quality which is necessary depends on the use to which the water will be put. Because uses vary, so also must quality standards. Maintaining any level of quality presents a problem of cost and depends on variations in natural water characteristics, in time and space, and variations in volume...

The Geological Survey has been the foremost agency in the investigation of ground‐water resources in the United States beginning about 1910. Most of the basic principles of modern ground‐water hydrology were developed in the Survey's program of cooperative investigations. Use of ground water in the United States in 1960 was about 17½ percent of all water uses, excluding water power. The use will probably increase, though at a decreasing rate. Although amount of use may level off, the...

Graphs and tables obtained from continuous records of surface-water temperature from five stations for the period july 1963 through December 1965 and of surface, salinity, dissolved oxygen, turbidity, tide-stage, wind data and bottom temperature from a single station are presented herein. Effects of powerplant cooling water on water temperature were...

The surface-water records for the 1966 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Indiana are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering states. The quality-of-water investigations of the U.S. Geological Survey are...

Guánica and the lower Rio Loco valley lie between the extensive agricultural development in Lajas Valley to the west and the industrial development at Guayanilla to the east. Having a protected deep-water port, the Guánica area is particularly well suited to further development. The economic growth of the area depends,...

The isotopic composition of lead in Red Sea chloride brine containing 0.5 ppm Pb is found to be similar to that of some Cenozoic ore leads such as galena at Rabigh in Saudi Arabia that may have formed during mineralization accompanying Tertiary...

The northern part of the Ten Mile and Taunton River basins is an area of about 195 square miles within Norfolk, Plymouth, and Bristol Counties in southeastern Massachusetts. The northern boundary of the area (plate 1) is the drainage divide separating these basins from that of the Charles, Neponset, and...

The food and food preferences of sea lamprey ammocoetes have not been investigated. The food of the larval American brook lamprey, Lampetra lamottei, in the Great Lakes region consisted mainly of diatoms and desmids according to Creaser and Hann. Schroll discussed the biology of feeding of ammocoetes of Lampetra planeri...

A paleomagnetic and K-Ar dating study of 44 upper Miocene and Pliocene volcanic units from the western United States suggests that the frequency of reversals of the earth's magnetic field during Pliocene time may have been comparable with that of the...

A theory of the utilization of laser techniques for ranging from the Earth to the Moon for the purpose of providing control points on the lunar surface at which the figure of the Moon is measured to an accuracy at least an order of magnitude better than that of...

An analysis of data on hydraulic parameters collected during a single boat trip down a river system is presented, plotted in form of the hydraulic geometry. A dimensionless rating curve is used to estimate bankfull and average discharge for basins of various sizes. When compared with gaging station data, estimates...
