Columbia River Basin Passive Integrated Transponder (PIT) Tag Adult Returns by Observation Site

The Columbia River Basin Passive Integrated Transponder (PIT) Adult
Returns by Observation Site data set provides daily counts of returns
of adult salmon containing passive transponders detected at
observation sites. The data set is provided courtesy of Pacific States
Marine Fisheries Commission. The Adult Returns by Observation Site
data set is featured at the 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.
