RECENT DEVELOPMENTS AT STREAMNET (JULY 10, 2002):
-------------------------------------------------
DATA ADDITIONS AND UPDATES
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.
REDEFINED SUBBASIN BOUNDARIES
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.
UPDATED MS-ACCESS DATA AVAILABLE
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
http://www.streamnet.org/online-data/accesstable.html.
INTERACTIVE MAPPING I
As of spring 2002, web-based interactive mapping is now available
on StreamNet. Go to http://map.streamnet.org/website 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.
INTERACTIVE MAPPING II
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.
PROTECTED AREAS DATABASE MODERNIZED
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 http://205.230.28.30:8080/website/protectedmapper/default.htm 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.
HYDROGRAPHY CONVERSION TOOL
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
http://www.streamnet.org/nhdllid/index.html.
SUMMARY OF MASS MARKING
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
http://www.streamnet.org/online-data/massmarkingmaps.html.
RESIDENT FISH DATA
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
http://www.streamnet.org/about-sn/project_management.html under
Briefing Papers and Miscellaneous.
INCREASED SPEED AND RELIABILITY
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 project@streamnet.org.
AND FOR YOU COMPUTER SPECIALISTS...
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.

ABOUT THE STREAMNET PROJECT
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 http://www.streamnet.org/about-sn.html. 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 (http://www.streamnet.org).
