The StreamNet Data Store is a searchable archive of data sets related to fish and other aquatic resources that are not of the specific data types included in the main StreamNet database. These data sets come from many different sources and are provided for download in their original formats. To add your own data set to the Data Store, use our Data Publishing Service.

StreamNet did not participate in creation of most of these data sets, and we are not able to answer questions about those we did not help develop. For questions about the data sets available from this page, please contact the originator of the particular data set.

Summary / Abstract Guidelines for locating data on 'Salmon Supporting Streams' as defined by the court in the pesticide spraying case.


A 2004 ruling by the United States District Court, Western District of Washington, at Seattle, established rules for use of pesticides near 'Salmon Supporting Waters.' It cited information on the StreamNet web site as the definition of these waters for Oregon and Washington.

While the court cited StreamNet as the source of information on 'Salmon Supporting Waters,' we do not have data specifically intended for that purpose. What we do have is information on salmon and steelhead distribution, broken down by life stage (i.e., spawning, rearing, migrating). This information indicates areas where salmon and steelhead occur for at least a portion of the year and what they are doing there. We presume these occupied streams would fit under any definition of 'Salmon Supporting Waters' as intended by the court. This information is the best place to start to find waters that support salmon or steelhead, as described below.

However, be aware that the information in the StreamNet database, while extensive, is not exhaustive. If a stream is included in the StreamNet anadromous fish distribution list, then that stream should be covered under the court's definition. But just because a stream is not included does NOT necessarily mean that salmon and/or steelhead do not occur there.
