NorWeST <\/SPAN><\/A>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. <\/SPAN><\/P>

This layer contains Scenario 1, modeled stream temperature from 1993-2011<\/SPAN>. Other attributes and model results are availalbe for download on the <\/SPAN>Modeled Stream Temperature Scenario Maps<\/SPAN><\/A> page.<\/SPAN><\/P>

The NorWeST scenarios include: <\/SPAN><\/P>

1) Adobe PDF format maps depicting historical and future modeled mean August stream temperatures, <\/SPAN><\/P>

2) graphs (JPG format) demonstrating the accuracy of the temperature model, and <\/SPAN><\/P>

3) GIS shapefiles (SHP format) representing the spatially modeled stream temperatures. Those shapefiles were used to create this ArcGIS online service.<\/SPAN><\/P>

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.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "These data were originally intended to be used for managing biological resources and predicting species distributions affected by August mean stream temperature.", "title": "Historical NorWeST modeled summer stream temperature scenarios for the western U.S.", "tags": [ "biota", "climatologyMeteorologyAtmosphere", "environment", "inlandWaters", "Climate change", "Ecology", "Ecosystems", "& Environment", "Hydrology", "watersheds", "sedimentation", "Forest & Plant Health", "Climate effects", "Invasive species", "Inventory", "Monitoring", "& Analysis", "Monitoring", "Natural Resource Management & Use", "Landscape management", "Wildlife (or Fauna)", "Fish", "Habitat management", "NorWeST", "stream temperature database", "stream temperature records", "modeling", "Spatial Stream Network", "stream network", "GIS", "aquatic vulnerability assessments", "decision support", "stream temperatures", "river temperatures", "hobo", "thermographs", "data loggers", "temperature model", "covariate predictors", "climate change", "global warming", "water", "river network", "stream network", "stream temperature model", "river temperature model", "modeled temperature", "observed temperature", "climate scenarios", "temperature sensor", "microclimate", "topoclimate", "big data", "citizen science", "crowd sourcing" ], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": 625000, "maxScale": 5000, "spatialReference": "", "accessInformation": "Funding for this project was provided by USDA Forest Service, Rocky Mountain Research Station.

*The stream temperature scenario shapefile data should be used with the understanding that the stream temperature values contained therein are modeled temperatures, not actual temperatures, and are subject to some imprecision associated with the modeling process. Stream temperatures were modeled based on instream recordings usually taken at hourly time steps during the month of August.
