Fall Fact Sheet No. 5 & Compact Action

September 21st, 2017

The Columbia River Compact convened by teleconference at 1:00 p.m. on Thursday, September 21, 2017 to review ongoing Treaty Indian and non-Indian commercial fisheries during the late fall management season.

TheĀ US v. Oregon Technical Advisory Committee (TAC) met Monday, September 18 and Tuesday, September 19 to update run-size numbers for the fall Chinook and summer steelhead runs. The upriver bright fall Chinook run is tracking near expectations, but tule fall Chinook stocks are tacking below expectations. TAC downgraded the tule stocks to 80% of the preseason forecast. TAC also reviewed the summer steelhead runs, the A-Index run is estimated to be 99,300 fish, and the B-Index run is estimated to be 8,500 fish, including 1,275 wild fish.

With regards to the non-Treaty mainstem commercial fishery, two nights of fishing during the late fall season had been completed. Based on observer data, wild B-Index steelhead impacts are estimated to be 2.7–4.8 mortalities, depending on whether cumulative in-season observed or the standard fall-season large mesh mortality rate is used. Using the standard fall-season mortality rate for large mesh gillnets, wild B-Index impacts to-date are at 85% of the current at 85% of the current commercial allotment. Were the third night of fishing to be held as previously scheduled, accrued impacts are estimated to be at 115% of the allotment, with the standard mortality rate applied. Therefore the staff recommended the third opener be rescinded.

With regards to the Deep River Select Area fishery, the staff recommended continuing with 15-hour periods through the remainder of the fall season.

Fall Fact Sheet No. 5 is appended in the form of a PDF file. The subsequent Compact Action Notice is posted as well.
