The NorWeST webpage hosts stream temperature data and climate scenarios in a variety of user-friendly digital formats for streams and rivers across the western U.S. The temperature database was compiled from hundreds of biologists and hydrologists working for >100 resource agencies and contains >200,000,000 hourly temperature recordings at >20,000 unique stream sites. Those temperature data were used with spatial statistical network models to develop 36 historical and future climate scenarios at 1-kilometer resolution for >1,000,000 kilometers of stream. Temperature data and model outputs, registered to NHDPlus stream lines, are posted to the website after QA/QC procedures and development of the final temperature model within a river basin. Open access to the data and the availability of accurate stream temperature scenarios will foster new research and collaborative relationships that enhance management and conservation of aquatic resources. Funding for the project was provided by the GNLCC and NPLCC with additional funds and in-kind support from the USFS, USGS, USFWS, NFWF, California Fish Passage Forum, and NASA.

With the concept of ‘riverscapes’ long pending to be acknowledged in the ‘landscape-centric’ legislative framework of Himalayan nations, conservation of native riverine species stays practically unheeded. This necessitates urgent prioritization of stream networks to conserve the lotic taxa under invasion pressures. Himalayan riverscapes are pervaded with the invasive-exotic brown trout Salmo trutta, posing serious threats to the co-occurring native, the snow trout Schizothorax richardsonii. Using intensive surveys (218.7km) and geostatistical stream network models (n=537), we contrasted snow trout in two stream networks with and without invasives, for assessing differences in their spatial distribution. Our models indicate invasion-induced relegations of natives from the river mainstem into headwaters, with large sections of mainstem occupied by invasives. Furthermore, a concerningly small percentage of potential habitat left for natives to occupy in the mainstem is threatened, where a ...

NorWeST is an interagency stream temperature database and model for the western United States containing data from over 20,000 unique stream locations. Temperature observations were solicited from state, federal, tribal, private, and municipal resource organizations and processed using a custom cleaning script developed by Gwynne Chandler. Summaries of daily, weekly, and monthly means, minima, and maxima are provided for observation years. The data summaries and location information are available in user-friendly file formats that include: 1) a map (PDF) depicting the locations of in-stream thermographs (temperature sensors) for each processing unit, 2) a GIS shapefile (SHP) containing the location of these sensors for each processing unit, and 3) a tabular file (XLSX) containing observed temperature database summaries for data generally ranging from 1993 to 2015, dependent on the processing unit. Each point shapefile extent corresponds to NorWeST processing units, which generally relate to 6 digit (3rd code) hydrologic unit codes (HUCs). The tabular data can be joined to the observation point shapefile using the ID field OBSPRED_ID. The NorWeST NHDPlusV1 processing units include: Salmon, Clearwater, Spokoot, Missouri Headwaters, Snake-Bear, MidSnake, MidColumbia, Oregon Coast, South-Central Oregon, Upper Columbia-Yakima, Washington Coast, Upper Yellowstone-Bighorn, Upper Missouri-Marias, and Upper Green-North Platte. The NorWeST NHDPlusV2 processing units include: Lahontan Basin, Northern California-Coastal Klamath, Utah, Coastal California, Central California, Colorado, New Mexico, Arizona, and Black Hills.These data have many potential uses including the assessment of stream temperature regimes, development of climate scenarios, understanding habitat and climate effects on stream temperatures, describing the thermal ecology of aquatic species, and conducting climate vulnerability assessments.For more information on the NorWeST stream temperature project see: https://www.fs.usda.gov/rm/boise/AWAE/projects/NorWeST.html

This study presents the application of a dendritic network model, specifically Spatial Stream Network Models, for predicting variations in strontium concentrations [Sr] and isotope ratios (87Sr/86Sr) in large river systems. We applied the model to the Taku River, a significant river system located within the accreted volcanic arc terranes of the northern Cordillera of North America. The model strongly fits the observed data with RMSE=0.05: r2=0.67 for [Sr] and RMSE=0.0003: r2=0.87 for 87Sr/86Sr. Our multidisciplinary data product offers a comprehensive tool with applications across the biosphere, hydrosphere, and geosphere. This model can address diverse research questions ranging from assessing the ecology of wild salmon fisheries to calculating Sr ocean budgets and evaluating silicate weathering feedback.

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 et al. 2012). Shapefile extents correspond to NorWeST processing units, which generally relate to 6 digit (3rd code) hydrologic unit codes (HUCs) or in some instances closely correspond to state borders. The line and point shapefiles contain identical modeled stream temperature results. The two shapefile formats are meant to complement one another for use in different applications. In addition, spatial and temporal covariates used to generate the modeled temperatures are included in the shapefile attribute tables. The NorWeST NHDPlusV1 processing units include: Salmon, Clearwater, Spokoot, Missouri Headwaters, Snake-Bear, MidSnake, MidColumbia, Oregon Coast, South-Central Oregon, Upper Columbia-Yakima, Washington Coast, Upper Yellowstone-Bighorn, Upper Missouri-Marias, and Upper Green-North Platte. The NorWeST NHDPlusV2 processing units include: Lahontan Basin, Northern California-Coastal Klamath, Utah, Coastal California, Central California, Colorado, New Mexico, Arizona, and Black Hills.These data were originally intended to be used for managing biological resources and predicting species distributions affected by August mean stream temperature.For more information on the NorWeST stream temperature project see: https://www.fs.usda.gov/rm/boise/AWAE/projects/NorWeST.html
