Up the Miami in very shallow water, predators were well fed at least.

Did you only see the dead fish at the bridge location? If so, it's possibly part of a nutrient enrichment program where they toss excess hatchery carcasses into various streams. I know of one such event that happened in the Nestucca area a couple weeks ago.

I have seen the hatcheries dump some carcasses in so.e of the creeks near Lebanon. I guess that was a fair while back.
I bet the hole with the carcasses was next to a bridge.....

I don't think they're "excess". I believe that's what the local hatchery does with the carcasses from fish they've harvested for the hatchery. But those don't wash up in a single spot like pictured.
-
I say "excess" because the fish in the close-up photo do not appear to have been spawned. Roughly half of the excess/surplus fish that show up in hatcheries are typically used in nutrient enrichment programs, alongside spawned-out carcasses.
Some of the skinnier ones in the first photo may have been spawned, but it's hard to tell.
Regardless, I'm confident these fish are part of a nutrient enrichment program. Possibly springers from the Trask River Hatchery, given its proximity to the Miami.

The area in question is not an easy drive to get to for a pickup truck let alone a fish transport truck, there were fish carcasses in single to 2-3 fish per area spanning the length of the river next to the road 1-2 miles. The photo is near a bridge but that’s the only deep hole close to the road. Most of the river is too shallow to natural wash carcass down river. If I’m by the hatchery I’ll check with them.

I didn't see that in the photos. Thanks for pointing it out. Time to get better reading glasses, I guess...

This river has an early run of Chum Salmon. Those fish will swim up thru 4" of water to get to the reds.
These were the 1st salmon I ever caught in a river. It's pretty interesting how they'll adapt to the conditions and spawn in the deeper parts of the river if necessary.
