angling improved over the weekend in the Columbia River from the river’s mouth
to Bonneville Dam, prompting the two-state Columbia River Compact this week to
take a cautious approach to extending early season fishing.
Compact at its call-in hearing this week, Wednesday, April 12, added two five
day periods for anglers downstream of the dam in the next two weeks, but
scheduled a check-in hearing between the two periods in case catch of upriver
fish, the limiting factor in the number of fish anglers can catch, exceeds the
limit of over 6,900 fish.
four-day lower Columbia River spring chinook season that closed Monday, April
11, showed a significant improvement in angling success than a previous period,
ending April 2, when anglers caught just 82 fish from 10,578 angler trips,
according to the Compact’s April 12, 2017, Winter Fact Sheet No. 11 (http://www.dfw.state.or.us/fish/OSCRP/CRM/FS/17/17_04_12wf11.pdf).
poor fishing has been due to river conditions with higher, colder and more
turbid water than normal. Those conditions persist, but somewhat improved last
week and angling success improved with the conditions.
seasonal water flow well above average, anglers have not had much success in
getting fish to bite, said Ron Roler, a Columbia River fishery manager for the
Washington Department of Fish and Wildlife.
April 10, anglers had caught only about 10 percent of the upriver spring
chinook available for harvest at this point in the season.
the period April 3 through April 10 anglers caught 1,052 spring chinook from
11,549 angler trips bringing the season total to 1,134 spring chinook and 35
steelhead from 22,127 angler trips. Some 117 spring chinook and 18 steelhead
were released. The number of fish caught April 11 had not become available at
the time of the Compact’s call-in hearing this week.
number of upriver fish caught through April 10 was estimated at 702 chinook, or
10 percent of the 6,905 available to this fishery prior to an expected run-size
update in early May.
fishing by the Washington Department of Fish and Wildlife is continuing to show
a significant increase in chinook abundance in the lower river, according to
the fact sheet. Test fishing April 9 increased to 7.8 fish per drift compared
to 6 fish per drift April 2, 3.1 fish per drift March 27 and 1.7 fish per drift
March 19. The highest count last year was 2.7 fish per drift on April 3, 2016.
fisheries in the lower river are finding plenty of spring chinook," Roler
said. "They're just not very quick to bite or move upriver under these
conditions. Often visibility in the river is so limited that the fish can't see
the anglers' lures."
should pick up fairly quickly once the fish start to move," Roler said.
at this point in the season few chinook are moving upriver beyond Bonneville
Dam, with just 217 of the fish passing the dam by April 10, one of the lowest
counts on this date since Bonneville Dam was built, according to John North of
the Oregon Department of Fish and Wildlife.
number over the dam had picked up to 305 fish by April 13, but it is still far
below last year’s count at this time of 2,515 fish and below the 10-year
average of 3,372 chinook (see http://www.fpc.org/web/apps/adultsalmon/R_yeartodatecomparisontable_results.php).
still too early to tell how big this run is, or if it will be larger or smaller
than our forecast,” said Stuart Ellis harvest management biologist with the
Columbia River Inter-Tribal Fish Commission and lead of the U.S. v Oregon
Technical Advisory Committee, which forecasts salmon and steelhead runs in the
the preseason forecast, approximately 160,400 upriver spring chinook are
expected to return to the waters upstream of Bonneville Dam this year, which is
about 80 percent of the 10-year average. That forecast is also down from last
year’s actual run of 187,816 fish.
total 2017 spring chinook forecast – including upriver and lower river chinook
– is down 17 percent to 227,890 fish from the 2016 actual run of 274,652 fish.
chinook returns to the Willamette River and other tributaries are also expected
to be lower than in recent years.
conditions at Bonneville dam are still higher, colder, and more turbid than
recent 5-year averages for the first half of April. Outflow at the dam is
nearly 400,000 cubic feet per second, which is almost 40 percent higher than
average, the Fact Sheet said.
temperature is 47 degrees Fahrenheit, colder than the average of 49 degrees F.
Visibility is 2 feet compared to the average of just over 4 feet. The river
stage at Vancouver is currently 12.9 feet and is forecasted to crest at 14.5
feet on April 15 (Action Stage is 15.0 feet and Flood Stage is 16.0 feet).
the end of the long meeting that had more fishing guides and fishing industry
people testifying than is normal, the Compact set two five day periods of
fishing for recreational anglers (see April 12 Columbia River Fishery Notice at
for spring chinook opened yesterday, April 13, and will be open through Monday,
April 17, and again from Thursday, April 20 through Sunday April 23. The
Council scheduled a check-in hearing at 1 pm, Wednesday, April 19. That meeting
could be canceled if catch and upriver mortalities during the first five-day
period are low.
staff had expected river conditions to improve and, along with the increasing
abundance of chinook in the lower river, it had expected catch to improve as
well. Staff recommended the “days-per-week” approach that the Compact adopted,
but suggested setting just one period, April 13 to April 16.
is open from Buoy 10 upstream to Beacon Rock (boat and bank) and from Beacon
Rock to Bonneville Dam from the bank for two adipose fin-clipped salmonids per
day, with only one being a chinook.
spring chinook fishery upriver from Bonneville Dam to the Washington-Oregon
border near Umatilla is open until May 5. If spring chinook return at or above
projections, fishery managers plan to provide additional fishing opportunities
in both areas later this spring, according to the Washington Department of Fish
fishing above Bonneville are allowed to retain one marked, hatchery-reared adult
chinook salmon as part of their daily limit of two salmon, two steelhead, or
one of each. Any chinook or steelhead without a clipped adipose fin and a
healed scar must be released unharmed.
gillnetters that have been fishing in off-channel select areas since January,
also saw an extension this week, but only at upper Youngs Bay and Blind Slough
in Oregon. Fishing in Select Areas will be open April 13 and April 17.
catch in Select Areas through April 11 totaled 583 chinook, or 81 percent of
the recent 5-year average harvest of 721 fish. The catch includes an estimated
76 upriver spring chinook.
