Tobias J. Kock, Theresa L. Liedtke, Brian K. Ekstrom, Dennis W. Rondorf, Chris Gleizes, Wolf Dammers, Scott Gibson, Jamie Murphy
2013, Open-File Report 2013-1116
Executive SummaryHistorically, adult summer steelhead Oncorhynchus mykiss returning to hatcheries on the lower Cowlitz River were sometimes transported and released in the river (recycled) to provide additional angling opportunity for the popular sport fishery in the basin. However, this practice has not been used in recent years because of concerns...

The U.S. Geological Survey Climate Geo Data Portal: an integrated broker for climate and geospatial data
David L. Blodgett
2013, Fact Sheet 2013-3019
The increasing availability of downscaled climate projections and other data products that summarize or predict climate conditions, is making climate data use more common in research and management. Scientists and decisionmakers often need to construct ensembles and compare climate hindcasts and future projections for particular spatial areas. These tasks generally...

Estimating irrigation water use in the humid eastern United States
Sara B. Levin, Phillip J. Zarriello
2013, Scientific Investigations Report 2013-5066
Accurate accounting of irrigation water use is an important part of the U.S. Geological Survey National Water-Use Information Program and the WaterSMART initiative to help maintain sustainable water resources in the Nation. Irrigation water use in the humid eastern United States is not well characterized because of inadequate reporting and...

Carl H. Lamborg, Gretchen J. Swarr, Konrad A. Hughen, Ross J. Jones, Scott Birdwhistell, Kathryn Furby, Sujata A. Murty, Nancy G. Prouty, Chun-Mao Tseng
2013, Geochimica et Cosmochimica Acta (109) 27-37
We have developed a technique that combines a high temperature quartz furnace with inductively coupled plasma-mass spectrometry for the determination of Hg stored in the annual CaCO3 bands found in coral skeletons. Substantial matrix effects, presumably due to the discontinuous introduction of CO2 to the gas stream, were corrected for by...
Aquatic insect assemblages associated with subalpine stream segment types in relict glaciated headwaters
Joshua S. Kubo, Christian E. Torgersen, Susan M. Bolton, Anne A. Weekes, Robert I. Gara
2013, Insect Conservation and Diversity (6) 422-434
1. Aquatic habitats and biotic assemblages in subalpine headwaters are sensitive to climate and human impacts. Understanding biotic responses to such perturbations and the contribution of high-elevation headwaters to riverine biodiversity requires the assessment of assemblage composition among habitat types. We compared aquatic insect assemblages among headwater stream segment types...

Justin G. Mychek-Londer, David B. Bunnell, Wendylee Stott, James S. Diana, John R. P. French III, Margret Chriscinske
2013, Transactions of the American Fisheries Society (142) 492-504
Ecological stability in the Laurentian Great Lakes has been altered by nonindigenous species, such as the Round Goby Neogobius melanostomus and dreissenid mussels, and by declines in native amphipods Diporeia spp. We evaluated whether these changes could influence diet overlap between three benthivorous fishes (Slimy Sculpin Cottus cognatus, Deepwater Sculpin...
Total dissolved gas and water temperature in the lower Columbia River, Oregon and Washington, water year 2012: Quality-assurance data and comparison to water-quality standards
Dwight Q. Tanner, Heather M. Bragg, Matthew W. Johnston
2013, Open-File Report 2012-1256
Significant Findings Air is entrained in water as it is flows through the spillways of dams, which causes an increase in the concentration of total dissolved gas in the water downstream from the dams. The elevated concentrations of total dissolved gas can adversely affect fish and other freshwater aquatic life. An...
Washington's volcanoes: Know your sleeping giants
Carolyn L. Driedger
2013, Washington Trails
Northwest hikers frequently hand down rich traditions of favorite trails to younger generations. While these multi-generational traditions provide the illusion of landscape permanence, observant hikers often witness geologic change in progress—rockfall, water erosion, and glacier change. You might recognize that your views of mountain landscapes are a little bit different...

Robert L. Runkel, Katherine Walton-Day, Briant A. Kimball, Philip L. Verplanck, David A. Nimick
2013, Journal of Hydrology (489) 26-41
The synoptic mass balance approach is often used to evaluate constituent mass loading in streams affected by mine drainage. Spatial profiles of constituent mass load are used to identify sources of contamination and prioritize sites for remedial action. This paper presents a field scale study in which replicate synoptic...

2013, Agricultural Water Management (116) 110-121
The ever-increasing demand for water due to growth of population and socioeconomic development in the past several decades has posed a worldwide threat to water supply security and to the environmental health of rivers. This study aims to derive reservoir operating rules through establishing a multi-objective optimization model for the...
Optimizing stream water mercury sampling for calculation of fish bioaccumulation factors
Karen Riva-Murray, Paul M. Bradley, Celeste A. Journey, Mark E. Brigham, Barbara C. Scudder Eikenberry, Christopher Knightes, Daniel T. Button
2013, Environmental Science & Technology (47) 5904-5912
Mercury (Hg) bioaccumulation factors (BAFs) for game fishes are widely employed for monitoring, assessment, and regulatory purposes. Mercury BAFs are calculated as the fish Hg concentration (Hgfish) divided by the water Hg concentration (Hgwater) and, consequently, are sensitive to sampling and analysis artifacts for fish and water. We evaluated the...

Approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafrost zone, more than twice as much C than in the atmosphere. The overall amount, rate, and form of C released to the atmosphere in a warmer world will influence the strength of the permafrost C feedback...
Field measurement of basal forces generated by erosive debris flows
S.W. McCoy, G.E. Tucker, J. W. Kean, J. A. Coe
2013, Journal of Geophysical Research F: Earth Surface (118) 589-602
It has been proposed that debris flows cut bedrock valleys in steeplands worldwide, but field measurements needed to constrain mechanistic models of this process remain sparse due to the difficulty of instrumenting natural flows. Here we present and analyze measurements made using an automated sensor network, erosion bolts, and a...

2013, Journal of Fish and Wildlife Management (4) 75-85
The eastern elliptio Elliptio complanata is a common, abundant, and ecologically important freshwater mussel that occurs throughout the Atlantic Slope drainage in the United States and Canada. Previous research has shown E. complanata glochidia to be host fish generalists, parasitizing yellow perch Perca flavescens, banded killifish Fundulus diaphanus, banded sculpin Cottus carolinae, and seven centrarchid species. Past...
Evaporative losses from soils covered by physical and different types of biological soil crusts
S. Chamizo, Y. Canton, F. Domingo, J. Belnap
2013, Hydrological Processes (27) 324-332
Evaporation of soil moisture is one of the most important processes affecting water availability in semiarid ecosystems. Biological soil crusts, which are widely distributed ground cover in these ecosystems, play a recognized role on water processes. Where they roughen surfaces, water residence time and thus infiltration can be greatly enhanced,...

Junran Li, Gregory S. Okin, Jeffrey E. Herrick, Jayne Belnap, Mark E. Miller, Kimberly Vest, Amy E. Draut
2013, Journal of Geophysical Research F: Earth Surface (118) 288-306
Aeolian transport is an important characteristic of many arid and semiarid regions worldwide that affects dust emission and ecosystem processes. The purpose of this paper is to evaluate a recent model of aeolian transport in the presence of vegetation. This approach differs from previous models by accounting for how vegetation...
Factors influencing storm-generated suspended-sediment concentrations and loads in four basins of contrasting land use, humid-tropical Puerto Rico
Allen C. Gellis
2013, Catena (104) 39-57
The significant characteristics controlling the variability in storm-generated suspended-sediment loads and concentrations were analyzed for four basins of differing land use (forest, pasture, cropland, and urbanizing) in humid-tropical Puerto Rico. Statistical analysis involved stepwise regression on factor scores. The explanatory variables were attributes of flow, hydrograph peaks, and rainfall, categorized...
