Record single-day chinook count shattered Monday at Bonneville Dam
The fall chinook counts are on a record setting pace in the Columbia River.
According to Joe Hymer, a state Fish and Wildlife biologist, the single-day count of 63,870 adult fall chinook at Bonneville Dam on Monday smashed the previous record set just last Saturday of 48,710.
The record before that was 45,884 fish set on Sept. 11, 2003.
“As far as I can tell going back through the annual counts since 1938, the 63,870 adult chinook counted at Bonneville may be a record daily count for all salmon, not just fall chinook,” Hymer said.
Other large single-day counts this season are: 42,445 on Sunday (Sept. 6); 48,710 on Saturday (Sept. 7); 25,956 on Friday (Sept. 6); 20,216 on Thursday (Sept. 5).
The 475,000 adult fall chinook counted at Bonneville Dam to date is the third highest on record for the entire run (from August through December).
Only 610,000 in 2003 and 584,000 in 2004 are larger.
