Isaak, D., S. Wenger, E. Peterson, J. Ver Hoef, C. Luce, S. Hostetler, J. Dunham, J. Kershner, B. Roper, D. Nagel, D. Horan, G. Chandler, S. Parkes, S. Wollrab. 2015. Development and application of NorWeST stream temperature climate scenarios for the Pacific Northwest. North Pacific Landscape Conservation Cooperative webinar, January 27.
NorWeST summer stream temperature scenarios were developed for all rivers and streams in the western U.S. from the > 20,000 stream sites in the NorWeST database where mean August stream temperatures were recorded. The scenarios include: 1) Adobe PDF format maps depicting historical and future modeled mean August stream temperatures, 2) graphs (JPG format) demonstrating the accuracy of the temperature model, and 3) GIS shapefiles (SHP format) representing the spatially modeled stream temperatures. The GIS shapefiles include stream lines and associated mid-points representing 1 kilometer intervals along the stream network. Stream lines were derived from the 1:100,000 scale NHDPlus dataset (USEPA and USGS 2010; McKay...

Existing stream temperature data were compiled from numerous federal, state, tribal, and private sources to develop an integrated regional database. Spatial statistical models for river networks were applied to these data to develop an accurate model that predicts stream temperature for all fish-bearing streams in the US portion of the GNLCC. Differences between model outputs for historic and future climate scenarios were used to assess spatial variation in the vulnerability of sensitive fish species across the GNLCC.FY2011Objectives: Develop a regional stream temperature model that incorporates important climate drivers, wildfire/riparian conditions, and geomorphic factors; Use the model to understand and predict...

The imminent demise of montane species is a recurrent theme in the climate change literature, particularly for aquatic species that are constrained to networks and elevational rather than latitudinal retreat as temperatures increase. Predictions of widespread species losses, however, have yet to be fulfilled despite decades of climate change, suggesting that trends are much weaker than anticipated and may be too subtle for detection given the widespread use of sparse water temperature datasets or imprecise surrogates like elevation and air temperature. Through application of large water-temperature databases evaluated for sensitivity to historical air-temperature variability and computationally interpolated to provide...
Workshop goals were to gather a diverse group of researchers and management professionals to focus on three objectives: Sharing current information regarding the effects of climate change on aquatic ecosystems Presenting analysis tools that could assist managers in addressing climate change Discussing management implications of climate change, the utility of existing tools, and future information & analysis needs
