Jessica D. Lundquist, James W. Roche, Harrison Forrester, Courtney Moore, Eric Keenan, Gwyneth Perry, Nicoleta Cristea, Brian Henn, Karl Lapo, Bruce McGurk, Daniel R. Cayan, Michael D. Dettinger
2016, Water Resources Research (52) 7478-7489
Regions of complex topography and remote wilderness terrain have spatially varying patterns of temperature and streamflow, but due to inherent difficulties of access, are often very poorly sampled. Here we present a data set of distributed stream stage, streamflow, stream temperature, barometric pressure, and air temperature from the Tuolumne River...
Geology, hydrology, water quality, and potential for interbasin invasive-species spread by way of the groundwater pathway near Lemont, Illinois
Robert T. Kay, P.C. Mills, P. Ryan Jackson
2016, Scientific Investigations Report 2016-5095
Invasive species such as Asian carps have the potential to travel in the egg, larval, or fry stages from the Des Plaines River (DPR) to the Chicago Sanitary and Ship Canal (CSSC) by way of the network of secondary-permeability features in the dolomite aquifer between these water bodies. Such movement...

Russell W. Perry, Rebecca A. Buchanan, Patricia L. Brandes, Jon R. Burau, Joshua A Israel
2016, San Francisco Estuary and Watershed Science (14)
As juvenile salmon enter the Sacramento–SanJoaquin River Delta (“the Delta”) they disperse among its complex channel network where they are subject to channel-specific processes that affect their rate of migration, vulnerability to predation, feeding success, growth rates, and ultimately, survival. In the decades...

Luke Schultz, Mariah P. Mayfield, Gabe T. Sheoships, Lance A. Wyss, Benjamin J. Clemens, Steven L. Whitlock, Carl B. Schreck
2016, Ecology of Freshwater Fish (25) 261-271
Pacific lamprey Entosphenus tridentatus is an anadromous fish native to the Pacific Northwest of the USA. That has declined substantially over the last 40 years. Effective conservation of this species will require an understanding of the habitat requirements for each life history stage. Because its life cycle contains extended freshwater rearing (3–8 years), the...
