Query & Graph Smolt Data:

Smolt Migration Timing for the Runs at Large

Tabular data includes real-time passage index, collection count, sample count, mortalities, descaling and sampling comments. Graphs include real-time passage index versus river flow. As the batches span two calendar days the enddate is used for the sample date. River flow in the SMP data is calculated for the exact sampling hours. Table of rearing dispositions possible by site/year/species.

  • SMP Data Query and Graph Returns passage index data, collection count, sample count, mortailities, descaling, mortality and sampling comments for 1985 through the current year. A graph containing passage index vs. river flow graphs for mainstem dams, and collection count vs. river flow graphs for upriver traps is also returned.

Cumulative PI Graphs include average run timing for past ten years for Yearling Chinook, Subyearling Chinook, Steelhead and Sockeye (LGR only) at Bonneville, McNary, Rock Island and Lower Granite Dams.
