the runs of summer chinook and sockeye wind down, their forecasted run sizes
were updated one last time by the U.S. v Oregon Technical Advisory Committee.
chinook run size, which last week stood at 74,100 upper Columbia River summer
chinook, this week was set as a final run size by TAC at its Monday, July 17
meeting, at 68,700 fish, according to the Compact Summer Fact Sheet No. 5 (http://www.dfw.state.or.us/fish/OSCRP/CRM/FS/17/17_07_18sf5.pdf), which was
presented this week at the Tuesday, July 18 two-state Columbia River Compact hearing.
The preseason forecast was 63,100 summer chinook.
also downgraded the sockeye salmon run to 88,200 fish as measured at the
Columbia River mouth. The preseason forecast was 198,500 sockeye, with 1,400 of
those fish thought to be Snake River sockeye listed as endangered under the
federal Endangered Species Act. TAC had previously downgraded the run to 90,400
analysis of the age composition of the 2017 sockeye run suggests that the
1-ocean and 3-ocean age components of the run were similar if not slightly
above their preseason forecasts, but the 2-ocean age component was less than a
third of its preseason forecast,” the Fact Sheet says. “These 2-ocean age
sockeye would have encountered the poor ocean conditions of 2015 in their
summer management period runs from June 16 through July 31, according to the
Fact Sheet. Chinook salmon passing Bonneville Dam or harvested during this time
period are managed as Upper Columbia summer chinook. The sockeye run size
includes any Columbia River sockeye no matter when it returns or passes
runs are nearing completion and TAC does not expect to meet again during the
summer management period. TAC will reconvene in early August to begin reviewing
salmonid returns for the fall management period.
week the Compact extended Treaty commercial gillnetting eight more days: 3.5
days July 19 to July 22 and 4.5 days July 24 to July 28. See the July 18
Compact Action Notice at http://www.dfw.state.or.us/fish/OSCRP/CRM/CAN/17/170718_notice.pdf
some of those days, the Tribes plan to lift the mesh restriction on nets
(currently, they are restricted to 7 inch nets). That will result in about 500
additional sockeye caught, assuming that some of the 250 boats that are
expected to fish use nets smaller than 7 inches.
the run of sockeye is expected to continue to decline the next couple of weeks,
as will the effort to fish for sockeye. According to Roger Dick of the Yakama
Nation, most of the gillnetters will continue fishing for chinook, which bring
a better price per pound than sockeye, so he doesn’t expect much change in the
catch of sockeye.
reason we are removing the restriction is that we have a good number of fish
left in our quotas,” Dick said.
on the updated run size forecasts and the US v Oregon Management Agreement,
Tribes are allocated 19,200 summer chinook and 6,174 sockeye. There is no
specific harvest limit for steelhead, although harvest is generally low in the
summer, the Fact Sheet says. “So far the steelhead run is tracking below the
expectation for a normally timed run at the preseason forecast size (112,100
A-index and 7,300 B-Index steelhead). The actual run size will be difficult to
estimate until the run is closer to 50 percent complete which typically occurs
near the middle of August.”
gillnetters, platform and hook and line fishers caught 13,257 chinook, 4,250
sockeye and 214 steelhead (about 29 percent of those are wild fish) through
July 15, according to Jon Hes, fishery scientist in the Fisheries Management
division of the Columbia River Inter-Tribal Fish Commission.
said the additional fishing time will add 3,100 chinook, 800 sockeye and 600
steelhead to the totals, which by the end of day July 28 is estimated to be
16,357 chinook, 5,050 sockeye and 814 steelhead.
in the Tribes’ allocation is 2,843 chinook and 1,124 sockeye, which will be
reserved for the platform and hook and line fisheries through the summer
season, Hes said. The Tribes will not ask for more gillnetting during the
July 17, 56,584 adult summer chinook had been counted at Bonneville Dam. That
is somewhat above expectations based on the pre-season forecast.
July 17, 85,954 sockeye had been counted at Bonneville Dam which is well below
expectations based on the pre-season forecast. Last year on July 17, some
336,398 sockeye had passed the dam and the 10-year average is 309,863 fish.
has not said how many of the sockeye this year are destined for the Snake
River. Some 372 have passed Ice Harbor Dam, the lower of the four lower Snake
River dams. Last year 841 had passed by July 17 and the 10-year average is 806.
Lower Granite Dam passage, the upper of the lower Snake River dams, was 189.
Last year the count on July 17 was 698 and the 10-year average is 738.
fall Compact hearing is scheduled for 1:00 PM Thursday July 27, 2017 at the new
Washington Department of Fish & Wildlife office (5525 S 11th Street,
Ridgefield, Washington 98642) to consider fall season Select Area commercial
and Treaty fisheries.
