Welcome to the IBIS Subbasin Data Center
Data used to create the sub-basin plans for the 62 sub-basins located within the U.S. portion of the Columbia River Basin has been collected from the various sub-basin planners and is available for download. However, some sub-basins did not have data and others have data sets so large that downloading them may prove to be problematic. If you have any questions and/or problems getting the data you need, please contact our Senior GIS Analyst and Web Administrator, Cory Langhoff at 541-753-2199 or via email at cory@nwhi.org
To navigate to specific subbasin dataset on this page, click on the appropriate Subbasin name in the
Table of Contents to the right. Subbasins are located in their respective Ecoprovince sections.
An alternative way to navigate to a specifc location is to use the Map Finder
button to the right. This allows for the interactive navigation to Ecoprovinces and Subbasins.
