StreamNet Newsletter #1

Significant data updates have occurred over the past year. Information on many dams and hatchery facilities has been added and updated. In addition, time series data have been updated and improved, including counts of spawners, spawning population size estimates, redd counts, and hatchery returns. Many other smaller additions and improvements have been accomplished.


Because the Northwest Power Planning Council redefined subbasin boundaries for the 2001 round of subbasin planning, we modified the query system so it now allows you to query for data based on the new 2001 subbasins as well as the 1990 subbasins. Eventually the 1990 subbasins will be removed, so we encourage use of the new ones for new work.


The entire StreamNet database is available for download in MS-Access format. This Access database was updated in June 2002 and is available for download at


As of spring 2002, web-based interactive mapping is now available on StreamNet. Go to to give it a try. No mapping software is needed on your computer. You can produce maps showing the locations of hatcheries and dams, fish distribution, ESUs, and more. These maps can be saved for incorporation into your own reports and presentations. This mapping capability is powerful but complex, so be sure to read the help files. We believe this ability to make maps will be useful to many people. Let us know of any ideas you have for additions to the mapping system.


In addition to simply making maps, you can query the StreamNet database based on selections made on the map. You can select a subbasin, HUC, stream, hatchery, dam, or county, and find the StreamNet fish data associated with your selection. If you search for data by HUC, you will be given links to data outside of StreamNet for the selected HUC. You can also perform some simple GIS analyses, such as creating a buffer around a stream and determining who owns the land within the buffer area. This is powerful but complex, so be sure to read the help files to get started.


StreamNet recently completed a project to map the NWPPC protected areas and the smolt density model data sets to the 1:100,000 scale. These data sets were previously referenced primarily with textual information about their locations, but were not defined precisely on a map. Spatially enabling the information allows us to present it more flexibly in our on-line query system and also to create maps and map-related products that better show the information. Because the protected areas are stored as legal definitions, these original definitions should still be considered official, and any map products should be considered derivative interpretations of these source descriptions.

We have implemented an interactive on-line mapping application at to assist in locating the protected areas information. This provides a convenient visual interface for the information. It is important to note that a small percentage of the protected areas, which were defined as text descriptions, could not be located on the 1:100,000 stream GIS layer and so can not be mapped. We do provide a table of the unresolved areas, which should be of help to local users and planners. Many of the unresolved areas relate to streams not included in the 1:100,000 scale hydrography, but which may be well known locally. We will add these to the 1:100,000 stream layer as they are identified. Please let us know if you can locate any of these streams.


StreamNet has been involved with development of the National Hydrography Dataset (NHD). To support this effort and to make data conversion easy between the LLID system and the NHD system at the 1:100,000 scale, we created an NHD/LLID conversion tool for Oregon, Washington, Idaho, and western Montana. You can download this tool for your own use at


StreamNet created a summary of the proportion of hatchery salmon and steelhead that received an adipose fin clip prior to release. You can obtain this report at


A progress report describing an initial inventory of resident fish data being collected by projects funded through the Power Planning Council's Fish and Wildlife Program and BPA has been prepared and posted on the StreamNet Reports page at under Briefing Papers and Miscellaneous.


With the hiring of a staff programmer in late 2001, we have been able to significantly improve the reliability of the StreamNet data query system. If you are familiar with StreamNet, we hope you have already noticed improved reliability. We also installed new servers in the past 6 months, significantly improving the speed (and reliability) of our web site and data query system. In late summer 2001 we changed the look and organization of our web pages. We hope you find that information is easier to find than in the past. We intend to continue making improvements to the data delivery system, so please let us know of any problems or suggestions by clicking the FEEDBACK button on the site, or send an email to


We have made significant progress moving our data delivery applications toward an open, standards-based system developed around XML and the Web Services model. This will allow us much greater flexibility in how and in what format we deliver data. For example, instead of a single method for searching for and delivering data, we can provide multiple customized search interfaces and data views based on user and use type. The benefits of this effort can already be seen in the customized data views delivered through our new interactive mapper.

StreamNet is a cooperative, multi-agency effort among the Columbia River Basin's state, tribal and federal fisheries agencies, the Northwest Power Planning Council (NWPPC), the Bonneville Power Administration, and the Pacific States Marine Fisheries Commission to compile fish related data. We compile and make available on our web site information intended to be useful to fisheries managers and researchers, land managers, planners, and others. We acquire, regionally standardize, and georeference data from multiple sources on a number of topics, including: fish distribution, fish abundance trends, hatchery releases and returns, harvest levels, migration barriers, hatcheries, and dams. We provide a catalog of photographs relevant to fish species and facilities in the region. We have begun developing information on habitat restoration projects and some limited information on water temperatures and macroinvertebrates. We maintain the official list of stream reaches the NWPPC has recommended be protected from dam construction, and we are the official keepers of the Pacific Northwest's 1:100,000 scale GIS streams layer. We provide pre-made maps and let you make maps interactively from data in the StreamNet database to meet your needs. We continually work to update these resources, so new information becomes available several times each year. We also provide customized data related services for participants in the NWPPC's Fish and Wildlife Program. When significant changes are made at StreamNet (new data or new ways to display them), we will email another short StreamNet News to those on the mailing list.

You can learn more about StreamNet at We exist in order to bring useful information to people such as you, and we welcome your questions and feedback. We also hope you will inform your colleagues about the resources available at StreamNet (
