Columbia River Basin Passive Integrated Transponder (PIT) Tags by Hydro Unit

The Columbia River Basin Passive Integrated Transponder (PIT) Tags by
Hydro Unit data set provides daily counts of salmon containing passive
transponders detected at Columbia Basin dams by USGS Hydro Unit. The
data set is provided courtesy of Pacific States Marine Fisheries
Commission. The PIT Hydro unit data set is featured at the University
of Washington, School of Aquatic and Fisheries Sciences, Columbia
Basin Research, Data Access Real Time (DART) program. DART provides
an interactive data resource designed for research and management
purposes relating to the Columbia Basin salmon populations and river
environment. Currently, daily data plus historic information dating
back to 1910 is accessible online. DART focuses on the Columbia Basin
dams and fish passage. Detailed information is brought in daily from
federal, state and tribal databases to provide a comprehensive
information tool. DART generates user-specified data files which can
be saved to a user's personal directory in a variety of formats
designed to be compatible with most spreadsheet programs. In addition,
DART has graphing capabilities which allow for the visual comparison
of multiple variables on one plot. These output formats are available
for the following data resources related to fish passage, PIT tags and
the river environment.
