Observed Stream Temperature Database Summaries

Database Summaries

These datasets can be viewed in ArcGIS Online (line data; point data) or in the interactive NorWeST viewer; they are also available from the FSGeodata Clearinghouse, or for individual processing units in the table below.

Daily summaries of observed stream temperature data we have permission to distribute are available here for download. Temperature data are posted to the website after application of QA/QC procedures, assembly of the data into a functional database, and fitting of the final stream temperature model for a river basin.

For additional details see:

1. QA/QC procedures with descriptions of the data summary format

2. Geospatial Metadata for Observed Site Locations

If you have any questions about the downloads on this page, please contact the web manager.

If there are questions regarding NorWeST data, please contact Gwynne Chandler (208.373.4372; gwynne.chandler@usda.gov), Sherry Wollrab (208.373.4371; sherry.p.wollrab@usda.gov), or Dona Horan (208.373.4399; dona.horan@usda.gov). Instructions for Stream Temperature Data Submissions.
