Stellar Salmon Returns Expected – but Don't Dust Off Fishing Gear Yet

BOISE, Idaho - Starting this month, more than 314,000 Chinook salmon are expected to make their way up the Columbia-Snake River system. It's an impressive forecast, but one expert cautions that the projections are still early, and last year, none of the salmon stock returns lived up to the early estimates.

According to fisheries biologist Doug DeHart, formerly Oregon's Chief of Fisheries, the most common methods for these "educated guesses" haven't proven especially reliable in recent years.

"That's led to the scientific folks that do this stuff having a whole series of little conferences on, 'Well, what's going wrong here? Should we change how we project?'"

The projections are used to set fishing seasons and make management plans for dams and hatcheries, among other purposes. Over the last 30 years, they've been higher than actual returns 11 times, and lower 19 times; seven of the forecasts were close to the actual fish numbers.

DeHart agrees it should be a good year for spring and fall salmon fishing. He says there's always uncertainty where nature is involved, although efforts to boost salmon survival appear to be working. Most notably among these is the court order to spill additional water over the Columbia River dams.

"That clearly produced additional survival. I mean, we saw it in the juveniles and now we're seeing it in the numbers of adults; one of the few new tools in the toolbox."

DeHart points out that at least 80 percent of the fish are from hatcheries, and there are separate counts for the endangered wild fish that don't look as impressive.

Fish forecast numbers are from the Washington Dept. of Fish & Wildlife and Northwest Sportsman December issue; see bit.ly/sXcT2W.
