Over the last two centuries, bull trout populations have declined across North America. The bull trout, Salvelinus confluentus, once thrived in the Columbia River Basin and coastal rivers of Washington and Oregon, extending north into British Columbia and Alberta.

Bull trout are members of the genus Salvelinus, which also includes Arctic char, brook trout, and lake trout. Like its relatives, male bull trout exhibit brilliant colors during the spawning season. Bull trout migrate during summer, traveling up to 150 miles from lakes and rivers upstream to their natal headwaters to spawn.

A variety of factors have been cited in the decline of bull trout. Habitat degradation and fragmentation, migratory fish passage obstacles, poor water quality, the effects of climate change, bounty fishing, and the introduction of non-native fish species.

Currently, American bull trout populations are scattered across portions of Oregon, Washington, Idaho, Montana, and Nevada. They populate several river systems including the Klamath,Columbia and Snake River Basins. In 1998, bull trout were listed as a threatened species under the Endangered Species Act.

In 2011, bull trout were re-introduced into the Clackamas River after a nearly 50-year absence. The reintroduction team included representatives from the U.S. Fish and Wildlife Service, Oregon Department of Fish and Wildlife, U.S.Geological Survey, and Mt. Hood National Forest. The project was one of several bull trout restoration programs that are ongoing in western river systems.

Recreational anglers in the Pacific Northwest can continue fishing for hatchery-reared spring chinook salmon through June 15 on a section of the Columbia River stretching 163.5 miles above Bonneville Dam.

The spring chinook fishery was extended by fishery managers from Washington and Oregon, who recently agreed that enough fish are still available under the catch limit to allow anglers to keep fishing until the summer chinook salmon season starts June 16. The popular spring chinook fishery was already scheduled to run through June 15 below Bonneville Dam.


Anglers can retain up to two hatchery adult chinook salmon, marked with a clipped adipose fin, as part of their daily catch limit. Sockeye salmon and hatchery-reared steelhead also count toward anglers’ adult daily limit.

All unmarked chinook and steelhead must be released unharmed.

Keta (chum) salmon are considered to be almost extinct on the Oregon side of the lower Columbia River, according to Oregon Department of Fish and Wildlife. A cooperative effort of the Oregon and Washington departments of fish and wildlife seeks to restore populations of this unique salmon species to the river.

During early April, the Oregon Department of Fish and Wildlife (ODFW) released 106,000 juvenile chum salmon into lower Big Creek in the first phase of project attempting to re-establish the species.

Keta salmon began to disappear from the Oregon side of the river more than 50 years ago. Biologists believe that severe habitat degradation and other factors played a key role in their decline.

The approximately 50 adult chum salmon male and female pairs used to produce the 2½ -inch fry at ODFW’s Big Creek Fish Hatchery were donated to Oregon by the Washington Department of Fish and Wildlife (WDFW). The adults were captured last fall in Grays River, a tributary of the lower Columbia on the Washington side of the river.

If adult keta salmon make it back to Big Creek, they will be captured and spawned at Big Creek Fish Hatchery to produce more eggs and fry for release in subsequent years.

ODFW hopes to generate enough seed stock over time to begin out-planting keta in other lower Columbia tributaries that are considered suitable for the species.

Keta salmon are generally more selective in their choice of spawning habitat than other species, according to Knutsen. These colorful salmon especially seek out upwelling areas associated with springs and seeps, he said, and they also prefer very clean, well-sorted gravel that is free of sands and silts that could smother their eggs.

If the program works as planned, chum salmon will reproduce naturally in sufficient numbers that they will no longer need a boost from Big Creek Hatchery.
