Back in the early 1990s when I first tried my luck at catching the famous upriver bright fall Chinook salmon in the Hanford Reach of the mighty Columbia River, I was amazed to see huge fish rolling all over the river.
THE NUMBER OF 5-YEAR-OLD FALL CHINOOK RETURNING TO THE COLUMBIA RIVER’S HANFORD REACH HAS DROPPED IN RECENT YEARS. PRIOR TO 2006, ONE-THIRD OF THE RUN CAME IN AS 5’S, ON AVERAGE, BUT SINCE THEN THE PERCENTAGE HAS DROPPED TO 18. DAVE SITTON CAUGHT THIS BEAST IN 2012. (YO-ZURI PHOTO CONTEST)
And when I say huge, I mean salmon running in the 30- to 40-pound range. The first time I hooked one of these giants, I fought it for 20 minutes before my 30-pound-test monofilament finally snapped when I tried to horse the fish into the net.
In those days, outdoor sections of newspapers often contained photos of smiling fishermen displaying monster fall Chinook caught with regularity.
Fast forward to the present and you have a totally different scenario. You simply do not see anglers landing many really large fish as before.
Toby Wyatt, owner/operator of Reel Time Fishing (208-790-2128) and who is one of the most successful guides on the Hanford Reach, says his clients land just a few fish in the 30-plus-pound range. Most of his catch ranges in the 10- to 20-pound range. He misses getting his clients into the monsters.
So what happened to the giants of the Hanford Reach?

Paul Hoffarth, Region III fisheries biologist for the Washington Department of Fish and Wildlife, confirms the drop in size of fish. Surprisingly and for unknown reasons, Hoffarth says that a significant shift in the age structure of fish happened all in one year — 2006.
Prior to 2006, roughly one-third (34 percent) of the upriver brights were the big 5-year-old fish and 37 percent were 4-year-olds.
Beginning in 2006, the percentage of 5-year-olds has averaged 18 percent (with a range of 10 to 28 percent) and has never recovered.
Hoffarth does not know why the decline happened so suddenly and no studies have been done to determine a cause or causes. Therefore, no one knows if the age structure will return to pre-2006 levels.
So we anglers are left in the dark as to what the future of the upriver bright population has in store in terms of the size of fish caught. Let’s hope whatever caused the flip in the age structure of these magnificent fish will just as suddenly flip the other way.
I would love to see a river full of rolling giants again.
