2009, Journal of Great Lakes Research (34) 245-252
To improve our ability to assess larval cisco (Coregonus artedi) populations in Lake Superior, we conducted a study to compare several sampling strategies. First, we compared density estimates of larval cisco concurrently captured in surface waters with a 2 × 1-m paired neuston net and a 0.5-m (diameter) conical net....

Vincent T. DePaul, Robert Rosman, Pierre J. Lacombe
2009, Scientific Investigations Report 2008-5145
The Coastal Plain aquifers of New Jersey provide an important source of water for more than 2 million people. Steadily increasing withdrawals from the late 1800s to the early 1990s resulted in declining water levels and the formation of regional cones of depression. In addition to decreasing water supplies, declining...

Ralph L. Seiler, James L. Wood
2009, Scientific Investigations Report 2009-5005
Some reaches of Clear Creek above U.S. Highway 395 have experienced severe erosion as a result of fires, extreme precipitation events, and past and current human activities in the basin. Previous evaluations of erosion in the basin have concluded that most of the sediment produced and transported in the basin...

Alec G. Maule, Scott P. Vanderkooi, John B Hamilton, Richard Stocking, Jerri Bartholomew
2009, North American Journal of Fisheries Management (29) 1743-1756
We evaluated a stock for restoring runs of fall Chinook salmon Oncorhynchus tshawytscha in the Upper Klamath River basin by monitoring its development in Iron Gate Hatchery and in net-pens in the Williamson River and Upper Klamath Lake in Oregon. We transferred age-1 hatchery fall Chinook salmon to net-pens in...
The length of channelized lava flows: Insight from the 1859 eruption of Mauna Loa Volcano, Hawai‘i
Jenny M. Riker, Katharine V. Cashman, James P. Kauahikaua, Charlene M. Montierth
2009, Journal of Volcanology and Geothermal Research (183)-139
The 1859 eruption of Mauna Loa Volcano, Hawai'i, produced paired 'a'ā and pāhoehoe flows of exceptional length (51 km). The 'a'ā flow field is distinguished by a long (> 36 km) and well-defined pāhoehoe-lined channel, indicating that channelized lava remained fluid to great distances from the vent. The 1859 eruption was further unusual...
Does mobility explain variation in colonisation and population recovery among stream fishes?
Paul L. Angermeier, Brett Albanese, James T. Peterson
2009, Freshwater Biology (54) 1444-1460
1. Colonisation and population recovery are crucial to species persistence in environmentally variable ecosystems, but are poorly understood processes. After documenting movement rates for several species of stream fish, we predicted that this variable would influence colonisation rates more strongly than local abundance, per cent occupancy, body size and...

2009, Fact Sheet 2008-3100
Complex natural resource issues require understanding a web of interactions among ecosystem components that are (1) interdisciplinary, encompassing physical, chemical, and biological processes; (2) spatially complex, involving movements of animals, water, and airborne materials across a range of landscapes and jurisdictions; and (3) temporally complex, occurring over days, weeks, or...
Estimated Perennial Streams of Idaho and Related Geospatial Datasets
Alan Rea, Kenneth D. Skinner
2009, Data Series 412
The perennial or intermittent status of a stream has bearing on many regulatory requirements. Because of changing technologies over time, cartographic representation of perennial/intermittent status of streams on U.S. Geological Survey (USGS) topographic maps is not always accurate and (or) consistent from one map sheet to another. Idaho Administrative Code...

Timothy T. Bartos, Cheryl A. Eddy-Miller, Laura L. Hallberg
2009, Scientific Investigations Report 2009-5024
Little existing information was available describing pesticide occurrence in ground water of Wyoming, so the U.S. Geological Survey, in cooperation with the Wyoming Department of Agriculture and the Wyoming Department of Environmental Quality on behalf of the Wyoming Ground-water and Pesticides Strategy Committee, collected ground-water samples twice (during late summer/early...
Spring and Summer Spatial Distribution of Endangered Juvenile Lost River and Shortnose Suckers in Relation to Environmental Variables in Upper Klamath Lake, Oregon: 2007 Annual Report
Summer M. Burdick, Scott P. VanderKooi, Greer O. Anderson
2009, Open-File Report 2009-1043
Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris were listed as endangered in 1988 for a variety of reasons including apparent recruitment failure.

Estimating Locations of Perennial Streams in Idaho Using a Generalized Least-Squares Regression Model of 7-Day, 2-Year Low Flows
Molly S. Wood, Alan Rea, Kenneth D. Skinner, Jon Hortness
2009, Scientific Investigations Report 2009-5015
Many State and Federal agencies use information regarding the locations of streams having intermittent or perennial flow when making management and regulatory decisions. For example, the application of some Idaho water quality standards depends on whether streams are intermittent. Idaho Administrative Code defines an intermittent stream as one having a...
