Add Your Data Set

Use our Data Publishing Service to add your data set to the Data Store.

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.

Date Data Set Published on StreamNet Data Store 05-02-2023
Project Name & Number 2009-004-00
Purpose of Data Set The proposal has two major components that are identified below:

1. Habitat degradation is attributed as a significant cause for the decline of numerous salmonid populations. The key objective of this proposal is to identify areas that have depressed populations within a sub-basin in the Columbia, and establish habitat conditions for these populations at different scales. Over the next 10 year period, various aspects of the habitat and fish populations will be inventoried, and treatment-control and before-after control impact (BACI) designs will be applied to both habitat conditions and population attributes (abundance and productivity) on these sub-basins.

2. The second phase of this project will be developed after baseline habitat data are collected and will focus on life cycle-based models for spring Chinook salmon. The approach used will develop life-cycle specific models to address life-history complexities, and intends to capture inter-annual variation in recruitment as a function of freshwater and early ocean/estuary variation. Based on data collected from the previous sections overlayed with life-history parameters, we will develop a quantitative modeling approach to estimate the annual variation in recruitment (and survival). This approach will probably use a collaborative effort with other agencies in the region (e.g., ODFW and NMFS) and tribes (e.g., CTUIR) that may have similar objectives.
