Default Final Stock Status Spring/Summer Chinook

OREGON AND WASHINGTON DEPARTMENTS OF FISH AND WILDLIFE

JOINT STAFF REPORT WINTER/SPRING FACT SHEET

FINAL 2006 IN-SEASON SUMMARY

August 2, 2006



Stock Status
Total Spring Chinook
The total spring Chinook run is comprised of Upriver, Willamette, Lower Columbia (Cowlitz, Kalama, Lewis) and Select Area spring Chinook.

The preseason forecast was for a total of 161,400 spring Chinook at the Columbia River mouth.



Upriver Spring Chinook
The 2006 preseason forecast was 88,400 fish. The final run size is estimated to be 132,200.

Bonneville Dam counts between January 1 and June 15 totaled 126,158 Chinook; however the run was the latest timed in recent history (the 50% date was May 12).


Willamette Spring Chinook
Preseason forecast for Willamette spring Chinook included 46,500 fish, with an estimated 10% of the run being wild. The final run is estimated to be 56,700.

Willamette Falls counts between January 1 and July 23 totaled 36,700 Chinook.

In-season harvest estimates for the mainstem Columbia River include 4,400 Willamette Chinook (kept plus release mortalities).



Wild Winter Steelhead
The preseason forecast for wild winter steelhead was 16,000 fish. The preliminary final run size is estimated to be near this number.



Management Guidelines
Spring Chinook are allocated through the U.S. v Oregon Management Agreement, the Fisheries Management Evaluation Plan (FMEP) for the Willamette River, The Willamette River Basin Fish Management Plan (WFMP), and through Washington and Oregon Commission guidance.

Endangered Species Act (ESA) limits restrict non-Indian harvest of wild upriver spring Chinook (2%) and wild winter steelhead (2%).

Impacts to upriver spring Chinook were allocated preseason at 57%/43% sport/commercial.

As part of the annual 8,000 sturgeon commercial guideline, 1,800 sturgeon were set aside for winter/spring commercial fisheries.


Fisheries Review
Non-Treaty Sport Fisheries
The mainstem Columbia River from the mouth at Buoy 10 upstream to the I-5 Bridge is open to selective salmon angling during January 1 through March 31 under permanent regulations with a two Chinook daily bag limit.

Regulations were adopted to extend the season below the I-5 Bridge through a target date of April 19; however, the fishery closed to Chinook retention April 14 (6 days early) until a run size update was available. The area from the Tongue Point/Rocky Point line upstream to Bonneville Dam reopened for Chinook retention during May 17 through June 15.

Except for specific fishing sanctuaries, the area from Bonneville Dam to McNary Dam was open March 16-30 as scheduled and reopened May 12 through June 15.

An estimated 87,000 angler trips below Bonneville Dam resulted in approximately 7,000 kept and 2,500 released Chinook and 2,400 kept and 350 released steelhead.

Catch above Bonneville Dam was projected at less than 600 upriver Chinook kept.

The Snake River near Little Goose Dam was open for hatchery Chinook retention May 17 through June 30, with an estimated 191 fish kept.



Non-Indian Commercial Sturgeon Fisheries
A total of 10 fishing periods (12-24 hour) were conducted in Zones 1-5 from January 10-February 22. Landings totaled 39 Chinook and 288 white sturgeon.


Non-Indian Commercial Salmon Fisheries
A total of five fishing periods (12-24 hours; 8-inch minimum mesh) were conducted in Zones 1-4 (upstream to Kelley Point) between February 23 and March 15.

The commercial fishery was put on hold in mid-March until a run size update was available

Six additional fishing periods (10-12 hours; 8-inch minimum mesh) occurred in Zones 1-5 between May 16 and June 2.

Landing for the season totaled 4,350 Chinook and 1,651 white sturgeon. The number of deliveries ranged between 21-91 per period. Prices for Chinook averaged about $5.51/lb (range $4.50-$10.00).

The total season catch was 4,389 Chinook and 1,939 white sturgeon.



Treaty Indian Commercial Fisheries
Treaty Indian ceremonial and subsistence (C&S) fisheries occurred for spring Chinook but no commercial fishing periods were conducted, due to the very late timing of the run.

Total C&S harvest was near 8,800 Chinook.



Summary of ESA Impacts
Impacts to listed upriver spring Chinook are estimated to be 0.59% in sport fisheries and 0.86% in commercial fisheries, for a total of 1.45% compared to the preseason guideline of 2.0%.

Impacts in the sport fishery were 52% of the preseason allocation and impacts in the commercial fishery were 100% of the preseason allocation. Non-Indian fisheries were only able to utilize 73% of the available impacts to upriver spring Chinook because of the record late timing of the run.

Wild winter steelhead mortalities are estimated to be less than 20 fish or about 0.1% of the preseason run size of 16,000 fish.

Impacts in the treaty Indian fishery are estimated to be 6.7% compared to the guideline of 8%.

I think that might be one boats total, for one night, 20 native steehead killed for the whole season?
That has got to be a typo, or we need a lot more observers.

Due to their rocket shape, steelhead that die in the gillnets tend to fall out when they expire. Oops...
