From: Juvenile salmonid migratory behavior at the mouth of the Columbia River and within the plume
Travel rate for emigrating yearling Chinook salmon, steelhead, and subyearling Chinook salmon smolts. Travel rate (rkm/day) is presented for two reaches, from rkm 153 and 8.3 and from the river mouth (rkm 8.3) to the plume array. Horizontal lines within each box represent median travel rate, ends of boxes represent the 25th and 75th percentile, and whiskers represent the 10th and 90th percentiles. The black dots represent the 5th and 95th percentile outliers. CH1, yearling Chinook salmon; STH, steelhead; CH0, subyearling Chinook salmon.
