This report presents the results of post-seasonal analyses including timing and relative magnitude of the outmigration, travel time for marked hatchery releases, and survival in mid-Columbia and lower Snake River index reaches. Travel time of marked yearling and sub-yearling chinook salmon (Oncorhynchus tsawytscha), sockeye salmon (Oncorhynchus nerka), and steelhead trout (Salmo gairdneri) is measured between specific sampling points in the system. Marked groups usually represent major hatchery production stocks. Survival estimates are computed for specific spring chinook and steelhead marked groups. Arrival time and duration of outmigration of the chinook, sockeye, coho (Oncorhynchus kisutch) and steelhead runs are reported at key sampling points. Hatchery and brand release information for 1986 is also listed.
