Sediment Loads and Yield, and Selected Water-Quality Parameters in Clear Creek, Carson City and Douglas County, Nevada, Water Years 2004-07
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...

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...
