Subbasin Summaries

The Northwest Power Planning Council is currently engaged in an effort to develop comprehensive subbasin plans throughout the Columbia River basin. The first step is to develop Subbasin Summaries that provide overview information on the resources in each subbasin. StreamNet has packaged existing data for each subbasin to assist in this effort. These have been preselected from the database and organized in spreadsheets. (The spreadsheets, originally done in 2001, were updated in February 2003. Both are available.) Some information is also presented on maps and as GIS data layers. These data can also be obtained using the Standard Query on the On-line Data portion of this website.

Before using the Subbasin Summary data, below, we recommend reviewing the README.txt file for a summary of the data that are available, and a description of the Data Types.

Note: Each subbasin spreadsheet contains 16 separate pages, including introductory explanations, many data types, and a table of literature relevant to the subbasin. Spreadsheets may take a long time to download over a phone modem.

Data for Use in Subbasin Summaries:

For a quick overview of the types of data available for each subbasin, download the data inventory by subbasin spreadsheet.

To obtain data for a specific subbasin, select a subbasin from the subbasins map or from the list of subbasins below.

Water temperature data. This is a compilation of water temperature information from across the Columbia Basin and other parts of the Northwest. It is not complete in all areas, but may be of use.

Protected Areas. These waters have been protected from further hydropower development by the Northwest Power Planning Council. This is a basin wide data set.

Smolt Density Model. From 1995 publication of calculated smolt densities, basin wide.

Electronic copies of the 1990 subbasin plans can be found here.
