Stream Temperature Modeling and Monitoring: Air Temperature Based Thermal Stream Habitat Model

    The Air Temperature Based Thermal Stream Habitat Model was originally developed from weather station information across the Columbia River basin in the Pacific Northwest. Multiple regression was used to predict mean annual air temperatures from elevation, latitude, and longitude with good success R^2 ~ 0.89). The model was developed as an alternative to PRISM data interpolations based on spline surface smoothing and should more accurately represent thermal conditions in stream valleys.

    Columbia River National Scenic Area GIS (Geographic Information Systems) Data

      This page contains metadata, or data about data, for our spatial data sets. The data sets are organized by theme which are shown in the table of contents frame. For example, if you are interested in a data set that has to do with water, just click on the water link in the table of contents. Then click on the name of the data set of interest to view the data dictionary. Each data dictionary will explain geographic information about the data set, who the data steward is, how the data set was built, and other associated information. It will also describe the database tables that are associated with the data set. Please contact the data steward (if noted) if you have questions about the content of the data. Their phone number is included within the data dictionary. The export files are shapefiles or geodatabases that have been compressed with WinZip. Projection is a local Albers projection defined for the area of Oregon and Washington in Region 6 of the Forest Service, NAD 83, units are in meters.

      Mt Hood National Forest GIS (Geographic Information Systems) data

        Located twenty miles east of the city of Portland, Oregon and the northern Willamette River valley, the Mt. Hood National Forest extends south from the strikingly beautiful Columbia River Gorge across more than sixty miles of forested mountains, lakes and streams to Olallie Scenic Area, a high lake basin under the slopes of Mt. Jefferson. These data sets were made using ESRI© ArcGIS.

        NRCS Regional Conservation Partnership Program - Columbia River Basin

          The Columbia River Basin provides habitat for salmon and steelhead, essential components of a healthy ecosystem and critical to Indian tribes and local communities. Loss of quality habitat because of pressures from population growth threaten fish numbers and the overall health of the basin. With this Critical Conservation Area designation, USDA will build on existing strong partnerships in the basin to work with agricultural producers to improve water quality and quantity in order to restore critical components of salmon habitat, aid in the recovery of Pacific salmon, and protect public health and the environment while maintaining a strong agricultural sector. The boundary of the CCA is a portion of the Columbia River Basin that includes essential fish habitat. This dataset includes a printer-friendly CCA map and shapefiles for GIS.

          NRCS Regional Conservation Partnership Program - RCPP Critical Conservation Areas

            Critical Conservation Areas (CCAs) are designated by the Secretary of Agriculture and represent an opportunity for many stakeholders to come together at a regional level to address common natural resource goals while maintaining or improving agricultural productivity. Partners, working closely with producers and communities, define and propose projects that will achieve regional natural resource goals while also meeting complementary local conservation priorities.
