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.

To search the Data Store, enter key words, project numbers, species, methods, etc. into the search box below and click "Search".

2019 Run-at-large PBT on juvenile Chinook

Data Categories Fish origin
Dates of Data 2019 TO 2019
Data Set Status Complete
Data Set Update Schedule None planned.
Date Data Set Published on StreamNet Data Store 04-01-2020
Project Name & Number 1991-029-00
Purpose of Data Set The USGS has developed a model to estimate daily abundance of hatchery and natural subyearlings passing Lower Granite Dam. As a way to validate daily abundance estimates of each group, fish were collected from the juvenile fish facility and had PBT analysis conducted to compare actual fish origin with origin estimated by the model.
Summary / Abstract These are parentage-based tagging (PBT) results from run-at-large subyearling fall Chinook salmon collected in at Lower Granite Dam in 2019 to validate fish origin for a juvenile abundance estimation model.
