WATER TEMPERATURE DATA AVAILABLE FROM STREAMNET

StreamNet currently has three water temperature resources.  Water temperature data have not been extensively developed by StreamNet.  Rather, the data available here are from three limited-duration projects.   While these data are not complete or exhaustive for the Northwest, we are making them available because they may be useful for parts of the region.

Prototype Water Temperature Database (45 MB download):  The first resource is a data set in a prototype database from a pilot project which StreamNet undertook in fiscal year 1999.  In this project we compiled water temperature data from the USGS state offices in Idaho, Oregon, and Washington.  These data are from the USGS gauging stations equipped with temperature sensors, and are primarily from large rivers in these three states.  These data were available as either instantaneous measurements or as daily summary data.  In addition to USGS data, we obtained instantaneous water temperature data from the Nez Perce (Idaho), Payette (Idaho), and Wallowa-Whitman (Oregon) National Forests.  These data are primarily from smaller streams.  The locations of all sample sites were tied to the 1:100,000 scale hydrography GIS layer maintained by StreamNet.  For the instantaneous data, daily summary data were calculated (such as maximum, minimum, mean, standard deviation, residuals, 7-day moving mean, N).  For all data, annual summary data were calculated (such as date range of measures, maximum, minimum, maximum 7-day moving mean).  We plan to add these data to the StreamNet query system in the future.  At this time, they can be downloaded here (45 MB download) in MS-Access97 format (zipped).  The database is designed so that queries can be run on the annual summary data, daily summary data, or instantaneous data.  If you would like these data in a different format or would like help in using this file, please contact Michael Banach by e-mail at mike_banach@psmfc.org or by phone at 503-595-3100.

Temperature Data Sources (45 MB download)  The second water temperature resource available here, also developed in fiscal year 1999, is simply a list of people who can serve as sources for water temperature data, and the locations for which they have data.  This list is available in the 45 MB download mentioned in the previous paragraph.  Another listing of contacts is the EPA Region 10 In-Stream Temperature Data Web Site.

EPA Contract Data Set  The third water temperature resource available here was developed by Mr. Stuart McKenzie (USGS hydrologist, retired) and Mr. Tony Laenen in fiscal year 1998 under a contract with EPA.  They collected and summarized water temperature data in the Columbia and Snake rivers and at the mouths of major direct tributaries to these rivers.  The data were collected for calibrating an EPA temperature model for these mainstem rivers.  StreamNet is providing a these data here as a convenience for people needing temperature data in the Columbia basin.
