This page is devoted to counting fish to pinpoint the status of runs on the Columbia River system.

With an emphasis on very recent, 10-day counts to hone in on what’s going on right now on the great Columbia River.

The flow of this page goes from the lower Columbia River to the upper reaches and the Snake River. So we start with Bonneville Dam and the Willamette River.

Columbia river between mouth and Bonneville

Bonneville Dam Steelhead Counts

You will see Steelhead counts over Bonneville in the winter and early spring months, but the bulk of the run starts in June with a peak from July through September.

Bonneville Dam Chinook Counts

Spring Chinook salmon fill the lower river in March but start to head over the dam in big numbers in April, tailing off in May, but transitioning right into summer chinook which peak in June, and tail off in July before the big wave of fall chinook heads over the dam in August through October.

Bonneville Dam Shad Counts

Shad start being counted over Bonneville Dam in May, but really peak in June before tailing off in July.

Bonneville Dam Sockeye Counts

Sockeye still start being counted on May, but peak in June and remain strong through July if the run is good.

Bonneville Dam Coho Counts

Finally, Coho still began being counted in August, but show up in two distinct runs, an A and a B run. The A run starts in August before tailing off in September, before the B run of Coho kicks in, in October, tailing off in November.

Willamette Falls Fish Counts

WIllamette falls and the columbia river map

The Willamette River runs right through the heart of Portland, OR and dumps into the Columbia River just NW of the metro area.

It’s so cool to have a river like the Willamette so close to a major metropolitan area. Counting fish over Willamette Falls is not just about fishing the Willamette, but a key data point for all lower Columbia River fisherman.
