Based on The Technical Advisory Committee (TAC) in-season forecasts for upriver stocks and the preseason forecasts for the lower river stocks, the Columbia River return is projected to reach nearly 1,200,000 adult fall Chinook in 2013.
- Fall Chinook passage at Bonneville Dam since August 1 totals nearly 717,500 adults. Counts remain strong, and cumulative passage has reached a record high. The run is typically around 80% complete by now.
- The total upriver fall Chinook run is a record run with 1,055,800 upriver origin fall Chinook expected to enter the Columbia River. TAC expects over 950,000 upriver origin fall Chinook to pass Bonneville Dam.
- The adult fall Chinook count at McNary Dam is 169,207. The 60,000 fish escapement goal was met on September 7.
- The adult fall Chinook count at Lower Granite Dam is 19,384 through September 17. The cumulative adult fall Chinook counts at Lower Granite, Little Goose and Lower Monumental Dams are all record high counts to date since the construction of the four lower Snake River Dams between 1961 and 1975.
