Four stratigraphic sections through alkali basalt flows of Oligocene-Miocene age (24 to 29 m.y.) in the As Sarat volcanic field, southwestern Saudi Arabia, were sampled for paleomagnetic study. Forty-two magnetically acceptable flows (139 samples) yield a mean direction of magnetization of D=-4.7°, 1=15.2° (α95=4.3°), which defines a paleomagnetic pole at 78.8°N, 247.8°E. Of these acceptable flows, 24 are normally magnetized and 18 are reversed. Parts of two sections of flows erupted apparently during the early phases of a polarity reversal of the earth's field. Although the mean paleomagnetic directions determined from each flow do not collectively define a strict Fisherian distribution, the fact that the mean directions for each of the four sections are nearly identical indicates that the overall paleomagnetic pole position is reliable. The magnetostratigraphy can be only generally correlated from one section to another apparently because of a lateral thickening and pinching out of many flows between sections.
The dispersion of directions due to secular variation of the upper Oligocene and lower Miocene field (standard angular deviation = 16.2°) is about the same as that produced by the recent field. If the rate of secular change during the time of As Sarat eruption was approximately that of the present, the rate of eruption during several sequences of As Sarat flows is estimated to be one flow about every 100 years.
The fact that the mean direction derived from 24 normally magnetized flows is significantly different from that derived from the 18 reversed flows supports the hypothesis of a displaced dipole source for the earth's field in late Oligocene to early Miocene time.
The results from As Sarat, as well as those from Aden, compared with paleomagnetic results from Late Tertiary rocks in Africa indicate with 95 percent confidence that the Red Sea has opened at least 2° in the past 5 m.y., and at least 4° in the past 25 m.y. The paleomagnetic results also indicate that the Arabian Peninsula was more equatorial in late Oligocene to early Miocene time than it is now, by an amount compatible with the opening of the Gulf of Aden.

Data from each area suggest that the intraslope basins are directly related to past and present salt-diapir activities and sea-level changes. The study areas had been selected on the basis of results of previous high-resolution seismic studies in the northern Gulf of Mexico.
North Horn Mountain is part of a deeply dissected plateau in central Utah which is characterized by deep, narrow, steep-walled canyons with local relief of more than 1,000 feet. Geologic units exposed in the North Horn Mountain area range in age from Late Cretaceous to Holocene and contain two mineable seams of Cretaceous coal. The area is in the drainage basin of the San Rafael River, in the Colorado River Basin. Runoff from the mountain is ephemeral. This runoff to the San Rafael River is by way of Cottonwood and Perron Creeks and represents less than 10 percent of their average annual runoff. Probable peak discharges (100-year flood) for the ephemeral streams draining North Horn Mountain are estimated to range from 200 to 380 cubic feet per second.
The chemical quality of surface water in the area is good. The water is generally of a calcium magnesium bicarbonate type with average dissolved solids less than 500 milligrams per liter. Annual sediment yield in most of the area ranges from 0.1 to 0.2 acre-foot per square mile but locally is as high as 1.0 acre-foot per square mile. Most of the sediment is eroded during cloudbursts.
Most of the ground water above the coal on North Horn Mountain probably is in perched aquifers. These aquifers support the flow of small seeps and springs. In some areas, the regional water table appears to extend upward into the coal. The principal source of recharge is precipitation that probably moves to aquifers along faults, joints, or fractures. This movement is apparently quite rapid. The dissolved-solids concentrations of ground water in the North Horn Mountain area range from less than 500 to about 1,000 milligrams per liter.
Coal mining on North Horn Mountain should have minor \"effects on the quantity and quality of surface water. The maximum predicted decrease in the annual flow of Ferron and Cottonwood Creeks is less than U percent. The sediment loads of affected streams could be significantly increased if construction were to take place during the summer cloudburst season. Subsidence, which usually follows underground coal mining, could create rock fractures through which a perched aquifer might be drained, thus depleting the flow of seeps or springs fed by that aquifer. It is considered unlikely that the mining will adversely affect the chemical quality of the ground water.

On both reservations fractured and weathered igneous and metamorphic rocks and alluvium are water bearing; however, no wells are known to derive their water entirely from alluvium. Well yields range from 2.5 to 250 gallons per minute. Springs occur where saturated fractured or weathered material intersects the land surface. Spring discharge ranged from 0 gallon per minute (November 1979) to 9.4 gallons per minute (November 1979). Few data are available for the surface water characteristics of the study area. One-time measurements of discharge at selected stream sites were made in late November 1979 and late May 1980; discharges ranged from less than 0.01 cubic foot per second to an estimated 3 cubic feet per second. Further study of the surface-water systems would provide a basis for estimating their development potential. The existing water-supply development on the Santa Ysabel Indian Reservation is adequate for the present residents. The Mesa Grande reservation was unoccupied in 1952, was reportedly unoccupied in November 1979, and has no developed water supply. Additional water can be developed for both reservations from the igneous and metamorphic rock, from presently undeveloped springs, and from perennial reaches of the larger streams. Except for excessive iron and sodium at some ground-water sites and excessive sodium at a few surface-water sites, the water is of suitable quality for domestic and agricultural use.

The Colby method is the simplest and most convenient to use. The mean annual total-sediment discharge for the four sites investigated ranged from 150 tons per day for the South Platte River at North Platte to 1,260 tons per day for the Platte River near Grand Island. The effective discharge at the sites ranged from 41 to 158 cubic meters per second. The probability of the effective discharge being equaled or exceeded ranged from 1 to 30 percent for the four sites.

The North Vernon Water Utility, supplying more than 25 percent of Jennings County's population, obtains its water from the Vernon Fork Muscatatuck River, although streamflow is less than the average daily withdrawal 69 days of the year. The U.S. Army, Jefferson Proving Ground, pipes water more than 5 miles and lifts it 375 feet for fire protection. Another Jennings County utility pipes water more than 15 miles to rural domestic consumers unable to locate sufficient ground-water supplies.
\nTwo nearly horizontal sequences of Paleozoic limestone and dolomite, intermittently separated by a thin, discontinuous shale unit, constitute the principal aquifer. Many wells tapping this aquifer are unable to supply single-dwelling needs, whereas others supply several dwellings with ease. All the wells tapping the aquifer have been located for the owners' convenience and are randomly located in relation to lineaments and fracture traces.
\nLineaments and fracture traces were observed throughout the study area, and those most easily interpreted are shown on a map at a scale of 1:48,000. Pleistocene drift, averaging 25-30 feet thick, covers most of the bedrock, but did not restrict the mapping of lineaments and fracture traces from aerial photographs.
\nThe lineament and fracture-trace map indicates probable locations of vertical or near vertical fractures in the bedrock. Wells drilled on these mapped features may yield adequate supplies for domestic use. Larger yields may be available in several areas of southwest Jennings County where lineaments parallel major stream channels.
\nWell placement is important in this area, as fractures are a principal source of water to wells. In areas of fractured bedrock, the most productive well locations are at the intersections of two or more mapped lineaments or fracture traces and at the lowest local altitude. Use of the lineament and fracture-trace map will not guarantee a sufficent supply of ground water but will minimize the chance of drilling an inadequate well.

Seventy-three streams were sampled three times during the 1979 and 1980 water years for specific conductance, pH, acidity, alkalinity, dissolved and total iron, dissolved and total manganese, dissolved sulfate, and dissolved solids. Benthic invertebrate populations were determined and botom material samples were analyzed for metals. Sixteen streams had pH, acidity, alkalinity, total iron, total manganese, and dissolved sulfate indicative of acid-mine drainage. These streams were most common in the Redbank and Blacklick Creek basins and in the Conemaugh and lower Kiskiminetas River basins. Benthic invertebrates were not found in 11 of 64 streams sampled. An additional 13 streams had low benthic invertebrate diversity indices. Low diversity indices were most common in the southern part of area 3. Low flow, mean flow, peak flow, and flow duration data are presented for gaging stations in area 3. Techniques for estimating these data for ungaged sites are presented and referenced. The functions of, and access to, the National Water Data Exchange, National Water Data Storage and Retrieval System, and Office of Water Data Coordination are explained.

Densities of coliform bacteria were low except in Prairie Creek, a tributary to Redwood Creek, where a State park, county fish hatchery, grazing land, lumber mill, and scattered residential areas are potential sources of fecal coliform bacteria.
Benthic invertebrate data indicated a diverse fauna which varied considerably between streams and among stream sections. Noteworthy findings include: (1) benthic invertebrates rapidly recolonized the streambed following a major storm, and (2) man-caused disruption or sedimentation of the streambed during low flow can result in drastic reductions of the benthic invertebrate community.
Seven species of fish representing species typically found in northern California coastal streams were captured during the study. Nonparametric statistical tests indicate that condition factors of steelhead trout were significantly larger at sampling stations with more insolation, regardless of drainage basin land-use history.
Periphyton and phytoplankton communities were diverse, variable in numbers, and dominated by diatoms. Seston concentrations were extremely variable between stations and at each station sampled.
The seston is influenced seasonally by aquatic productivity at each station and amount of allochthonous material from the terrestrial ecosystem. Time-series analysis of some seston data indicated larger and sharper peak concentrations being flushed from the logged drainage basin than from the control drainage basin. (USGS)
