From: Juvenile salmonid migratory behavior at the mouth of the Columbia River and within the plume
Residence time for emigrating juvenile salmonids between the river mouth and plume array. Residence time (days) was calculated using the last detection at the Columbia River mouth to the last detection on the plume array for (A) yearling Chinook salmon, (B) steelhead, and (C) subyearling Chinook salmon. CH1, yearling Chinook salmon; STH, steelhead; CH0, subyearling Chinook salmon.
