  1. NOAA Mainstem PIT Tag Research NWPCC Tagging Forum-PIT tags March 22, 2012 Bill Muir bill.muir@noaa.gov Northwest Fisheries Science Center NOAA Fisheries

  2. Outline • Reach survival • Hydropower system survival • Hydropower system travel time • Seasonal effects of transport • PIT tag trawl • Bird predation

  3. Reach Survival Estimates • Used to assess progress in improving inriver travel time and survival and identify problem areas in the hydropower system

  4. Reach Survival Estimates • Used to assess progress in improving inriver travel time and survival and identify problem areas in the hydropower system • Relies mostly on tagging from other studies throughout the basin

  5. Reach Survival Estimates • Used to assess progress in improving inriver travel time and survival and identify problem areas in the hydropower system • Relies mostly on tagging from other studies throughout the basin • Under represented species tagged at Lower Granite (wild Chinook, wild and hatchery steelhead)

  6. Reach Survival Estimates • Used to assess progress in improving inriver travel time and survival and identify problem areas in the hydrosystem • Relies mostly on tagging from other studies throughout the basin • Under represented species tagged at Lower Granite (wild Chinook, wild and hatchery steelhead) • Estimates are from tailrace to tailrace (1 dam and reservoir)
