2023 Columbia Springer Update

Columbia spring Chinook managers this evening issued an update on the fishery that closed last Tuesday, reporting that anglers kept an estimated 2,910 of the salmon in the lower river, including 26 percent of the constraining above-Bonneville quota.


Even with the four-day extension in a usually hot time of the month, fishing was far slower than expected, but ODFW and WDFW note that mainstem tangle net test fishing has seen “steadily increasing” catches as April’s worn on.

Still, with no Columbia River Compact calls scheduled, springer anglers will bide their time before the runsize update by focusing their efforts on local tributaries or the gorge pools, which are open in part, though the update says none have been caught there since they opened.

Here are pertinent outtakes from the update:


• As of April 17, the recent five-day average outflow at Bonneville Dam is 163 kcfs compared  to the five-year average of 186 kcfs. The current five-day average water temperature at  Bonneville Dam is 46°F compared to the five-year average temperature of 48°F. The five-day  average visibility at Bonneville Dam is 5.6 feet which is greater than the five-year average of  4.6 feet.  


• Adult Chinook passage at Bonneville Dam through April 16 totals 830 adult fish, compared to  the recent 10-year average of 3,680 fish and the recent five-year average cumulative adult  count of 862 fish (range 250–1,956). It is still very early in the return; the 10-year average  proportion complete at Bonneville Dam is approximately 2.2% by April 16. 

• Weekly test fishing in the lower Columbia River using tangle nets began on March 13 this  year, with five weeks completed to date. Weekly catch rates have been 0.0, 0.1, 0.2, 0.9 and  1.8 Chinook per drift, which are consistently lower when compared to the same timeframe in  2022 but are steadily increasing. All test fishing results are available on the WDFW test fishing  webpage (click here).  


Columbia River Recreational Spring Chinook Fishery – Downstream of Bonneville Dam  

• The lower Columbia River (LCR) mainstem recreational spring Chinook fishery was open  under temporary regulations from March 1 – April 11 between Buoy 10 and Bonneville Dam.  

• Water conditions were favorable (low and clear) throughout the season but colder than average. 

• The preliminary kept catch through April 11 is estimated to be about 2,910 adult spring  Chinook from approximately 42,900 angler trips.  

• Total mortalities of upriver-origin spring Chinook in the fishery through April 11 are estimated  to be 1,715 adult Chinook, or 26% of the 6,487 available to this fishery prior to a run-size  update. 

• During the Compact/Joint State Hearing on April 4, 2023, the states extended the LCR  recreational fishery for four additional days past the original closure date of April 8 to allow  for additional opportunity before catches became too volatile in mid to late April. With the  current low passage at Bonneville and potential for very high catch rates, fishery managers are  not prepared to consider additional fishing time until we get closer to the run size update. The  run size update is provided by U.S. v. Oregon Technical Advisory Committee and typically  occurs in mid-May, when substantial numbers of upriver spring Chinook have crossed  Bonneville Dam. The Joint State Staff will continue to evaluate the return and make  recommendations for additional angling opportunity when more Chinook have passed  Bonneville Dam and catch volatility has decreased. 

Columbia River Spring Chinook Recreational Fishery – Bonneville Dam to OR/WA Border 

• The recreational spring Chinook fishery is currently open under temporary regulations through  May 6 in the mainstem Columbia River from Bonneville Dam upstream to the OR/WA border (upstream of McNary Dam). The pre-run-update guideline for this fishery is 927 upriver Chinook mortalities. • Through April 16, no catch has been observed from approximately 200 angler trips in the  recreational fishery above Bonneville Dam.


• No Compact or Joint State hearings are scheduled at this time. The Joint State Staff will  continue to monitor fish runs and ongoing fisheries and recommend additional hearings as  needed.
