This market will resolve to "Yes" if "Chinook" Adult Passage Annual Count at Bonneville Dam from January 1, 2026 through October 31, 2026, 11:59 PM ET, exceeds the listed value. Otherwise, this market will resolve to "No". Each market in this event will resolve independently, and any number of these markets, including all or none, may resolve to "Yes". The qualifying data is the Adult Passage Annual Count for Bonneville Dam for the date range January 1, 2026 through October 31, 2026, 11:59 PM ET. Jack Chinook will not be considered for resolution. A value exactly equal to the listed value will resolve to "No". The value read for that date range is final, and counts for dates after October 31, 2026 are disregarded. The count is used as published, without expansion, interpolation, or adjustment, and annual and year-to-date summary totals are not used. The resolution date is November 3, 2026, 11:59 PM ET, extending to November 17, 2026, 11:59 PM ET if the count through October 31, 2026 has not been published by that time. If DART has not published the count through October 31, 2026 by November 17, 2026, 11:59 PM ET, this market will resolve based on the available data. If Columbia River DART becomes unavailable and does not re-appear by November 17, 2026, 11:59 PM ET, all markets will resolve to "No". No substitute data provider will be used. Revisions published before the controlling deadline are incorporated; revisions published after the controlling deadline are disregarded.
