C. D. Farrar, D. L. Lyster
1990, Geothermal Resources Council Transactions (14) 669-674
In the early 1980's, renewed interest in the geothermal potential of the Long Valley caldera, California, highlighted the need to balance the benefits of energy development with the established recreational activities of the area. The Long Valley Hydrologic Advisory Committee, formed in 1987, instituted...
Estimating groundwater exchange with lakes: 1. The stable isotope mass balance method
David P. Krabbenhoft, Carl J. Bowser, Mary P. Anderson, John W. Valley
1990, Water Resources Research (26) 2445-2453
Groundwater inflow and outflow contributions to the hydrologic budget of lakes can be determined using a stable isotope (18O/16O) mass balance method. The stable isotope method provides a way of integrating the spatial and temporal complexities of the flow field around a lake, thereby offering an appealing alternative to the...
Estimating groundwater exchange with lakes: 2. Calibration of a three-dimensional, solute transport model to a stable isotope plume
David P. Krabbenhoft, Mary P. Anderson, Carl J. Bowser
1990, Water Resources Research (26) 2455-2462
A three-dimensional groundwater flow and solute transport model was calibrated to a plume of water described by measurements of δ18O and used to calculate groundwater inflow and outflow rates at a lake in northern Wisconsin. The flow model was calibrated to observed hydraulic gradients and estimated recharge rates. Calibration of...

Organochlorine pesticide residues in bed sediments of the San Joaquin River, California
Robert J. Gilliom, Daphne G. Clifton
1990, Journal of the American Water Resources Association (26) 11-24
Bed sediments of the San Joaquin River and its tributaries were sampled during October 7–11, 1985, and analyzed for organochiorine pesticide residues in order to determine their areal distribution and to evaluate and prioritize needs for further study. Residues of DDD, DDE, DDT, and dieldrin are widespread in the fine-grained...
Selenium speciation methods and application to soil saturation extracts from San Joaquin Valley, California
John L. Fio, Roger Fujii
1990, Soil Science Society of America Journal (54) 363-369
Methods to determine soluble concentrations of selenite, selenate, and organic Se were evaluated on saturation extracts of soil samples collected from three sites on the Panoche Creek alluvial fan in the western San Joaquin Valley, California. The methods were used in combination with hydride-generation atomic-absorption spectrometry for detection of Se,...

Roy W. Fairchild, Ronald L. Hanson, Robert E. Davis
1990, Circular 91
Rocks that make up the Arbuckle-Simpson aquifer crop out over ~500 mi2 in the Arbuckle Mountains province in south-central Oklahoma. The aquifer consists of limestone, dolomite, and sandstone of the Arbuckle and Simpson Groups of Late Cambrian to Middle Ordovician age and is about 5,000-9,000 ft thick. The rocks were...
An efficient deterministic-probabilistic approach to modeling regional groundwater flow: 1. Theory
Chung-Cheng Yen, Gary L. Guymon
1990, Water Resources Research (26) 1559-1567
An efficient probabilistic model is developed and cascaded with a deterministic model for predicting water table elevations in regional aquifers. The objective is to quantify model uncertainty where precise estimates of water table elevations may be required. The probabilistic model is based on the two-point probability method which only requires...
An efficient deterministic-probabilistic approach to modeling regional groundwater flow: 2. Application to Owens Valley, California
Gary L. Guymon, Chung-Cheng Yen
1990, Water Resources Research (26) 1569-1581
The applicability of a deterministic-probabilistic model for predicting water tables in southern Owens Valley, California, is evaluated. The model is based on a two-layer deterministic model that is cascaded with a two-point probability model. To reduce the potentially large number of uncertain variables in the deterministic model, lumping of uncertain...
National Coastal Geology Program: a plan of geologic research on coastal erosion, coastal wetlands, polluted sediments, and coastal hard-mineral resources

1990, Report
More than 50 percent of the U.S. population currently live within 50 miles of an ocean, Great Lake, or major estuary. According to forecasts, the concentration of people along our coastlines will continue to increase into the 21st century. In addition to residential and commercial buildings and facilities worth tens...

Reversed-phase high-performance liquid chromatography—thermospray mass spectrometric (HPLC—MS) characteristics of four sets of lactonic complexes (one 4-butyrolactones and three dilactone complexes) derived from antimycin A were investigated. Three types of 8-hydroxy analogues were also included in the study. Pairs of a–b structures isomeric at the 8-acyloxy ester side-chains were best separated...

Macroinvertebrate communities associated with three aquatic macrophytes (Ceratophyllum demersum, Myriophyllum spicatum, and Vallisneria americana) in Lake Onalaska, Wisconsin
E.W. Chilton II
1990, Journal of Freshwater Ecology (5) 455-466
The standing crop and species diversity of macroinvertebrates associated with wild celery (Vallisneria americana), Eurasian watermilfoil (Myriophyllum spicatum), and coontail (Ceratophyllum demersum) were examined in Lake Onalaska, Pool 7 of the upper Mississippi River, during summer 1983. Although Ceratophyllum generally supported the largest invertebrate standing crop (number per g plant...

P.A. Gilderhus
1990, Progressive Fish-Culturist (52) 189-191
The anesthetic benzocaine was tested for efficacy and safety for spawning-phase chinook salmon (Oncorhynchus tshawytscha) and Atlantic salmon (Salmo salar) at federal fish hatcheries. Tests were conducted in the existing hatchery water supplies (soft water; temperatures, 10–13 °C. Crystalline benzocaine was dissolved in ethanol (1 g/30 mL), and aliquots of...

James G. Wiener, William F. Fitzgerald, Carl J. Watras, Ronald G. Rada
1990, Environmental Toxicology and Chemistry (9) 909-918
We studied the partitioning of mercury (Hg) among air, water, sediments and fish at Little Rock Lake, a clear water seepage lake in north-central Wisconsin. The lake was divided with a sea curtain into two basins, one acidified with sulfuric acid to pH 5.6 for two years and the other...
Effects of fish predation on invertebrates associated with a macrophyte in Lake Onalaska, Wisconsin
E.W. Chilton II, F.J. Margraf
1990, Journal of Freshwater Ecology (5) 289-296
We tested the effects of fish predation on the macroinvertebrates associated with Vallisneria americana (Michx) by using enclosure/exclosure experiments in lake Onalaska, Wisconsin. Four treatments were used: open water (cageless) controls, cage-effect controls (partially enclosed cages), exclosures (all fish removed), and enclosures (cages stocked with a known density of bluegills...

Remagnetization and northward coastwise transport of Franciscan Complex rocks, northern California: A reinterpretation of the paleomagnetic data
Jonathan T. Hagstrum
1990, Tectonics (9) 1221-1233
Previous paleomagnetic studies of accreted oceanic rocks within the Franciscan Complex of northern California have concluded that these rocks originated far to the south of their present positions with respect to the North American continent. Based on positive “fold” tests, the characteristic remanent magnetizations were inferred to predate accretion-related deformation...
The age of the Keystone thrust: Laser-fusion 40Ar/39Ar dating of foreland basin deposits, southern Spring Mountains, Nevada
Robert J. Fleck, Michael D. Carr
1990, Tectonics (9) 467-476
Nonmarine sedimentary and volcaniclastic foreland-basin deposits in the Spring Mountains of southern Nevada are cut by the Contact and Keystone thrusts. These synorogenic deposits, informally designated the Lavinia Wash sequence by Carr (1980), previously were assigned a Late Jurassic to Early Cretaceous(?) age. New 40Ar/39Ar laserfusion and incremental-heating studies of a...
Breeding biology of the spotted salamander Ambystoma maculatum (Shaw) in acidic temporary ponds at Cape Cod, USA
J. W. Portnoy
1990, Biological Conservation (53) 61-75
The relationship between water chemistry and breeding success of spotted salamanders Ambystoma maculatum (Shaw) was examined in temporary woodland ponds on outer Cape Cod, Massachusetts in 1985 and 1986. Most pond waters were dilute (3median coductivity = 57 umhos cm−1 (1 umhos cm−1 = 0·1 mSm−1)), acidic (median pH = 4·82), and highly colored...
