File S1 - Assessing the Relative Importance of Local and Regional Processes on the Survival of a Threatened Salmon Population

Tables S1–S3. Table S1. Juvenile spring/summer Snake River Chinook salmon with PIT tags included in the study. Year of emigration and date and size at tagging are reported. The otolith-derived estimates for size at marine entry (FLME) and duration of time at liberty prior to marine entry (Release to ME) are included with estimated mean in-river migration rate (In-river), date of marine entry (ME) and the date and location of final detection along the Columbia River hydropower system. Table S2. Comparison between marked and unmarked Snake River yearling sp/su Chinook salmon. Mean (SE) size at marine entry, marine growth rate, date of marine entry, marine migration rate (body length per second), and size at capture by emigration year. Table S3. Annual values for model parameters. Smolt-to-adult return ratios (SAR) for Snake River spring/summer Chinook salmon; NPGO4_6 =  mean value from April to June; PDO7_9 =  mean value from July to September; CPUE6 =  catch of yearling Chinook (fish km−1) in June; and CCI6 =  Copepod Community Index in June are included.
