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
||This abbreviated status update for westslope cutthroat trout (Oncorhynchus clarkii lewisi, WCT ) relies primarily on information contained in a 2009 update of the WCT status database. This report is presented as a summary of information primarily obtained during nine (9) workshops held between January and March, 2009. Biologists and ArcGIS technical experts from several state, federal, and Tribal agencies along with representatives of private companies combined their collective knowledge and skills in the effort. The 2009 database update for WCT expands the information originally developed in 2002.
The database is managed and maintained as a component of the WCT interagency conservation working group's program for conservation of WCT. Coordination leadership for the WCT conservation effort and more specifically for management of the database is currently provided by Idaho Department of Fish and Game. This summary report relies heavily upon a number of database queries that were provided by Idaho Fish and Game.
This summary updates previous WCT status assessments by using an updated version of the 2002 protocol which allowed for an expansion of information contained in the database. The informational components of the updated protocol included a further refinement of historically occupied range, a review and adjustment of the current distribution that included additional characterizations, and identification of 'conservation populations' within the current distribution. The assessment of restoration and expansion possibilities for WCT within the context of the historical range was not completed. To the extent possible comparisons between the 2002 and 2009 reporting periods will be presented. A detailed range-wide status report (Shepard et al. 2003) and a scientific publication (Shepard et al. 2005) were developed from information contained in the 2002 WCT database. It is recommended that additional publications be prepared using the 2009 information.
