PORTLAND, Ore. (AP) — Hundreds of thousands of salmon are making their way from the ocean up the Columbia River this month, a windfall for salmon eaters, and for tribal and recreational fishermen in the Pacific Northwest.

It’s one of the largest runs since dam construction blocked fishes’ river passage. The run is forecast at 1.5 million adult and young adult salmon by year’s end, although fish managers say the final number may turn out to be lower.
