BONNEVILLE DAM —Northwest salmon fishery managers have plenty to celebrate this fall: The region’s salmon runs shattered modern-day records this year, returning to the Columbia River Basin in the highest numbers since fish counting began at Bonneville Dam more than 75 years ago.

This year’s run of about 2.3 million salmon and steelhead exceeds the previous record of 2.1 million set in 2011, according to the Fish Passage Center. This year also brought a new single-day record, when 67,521 adult fall Chinook passed by Bonneville Dam on Sept. 8 – the highest one-day total in more than seven decades.
