"Normally, we have about 700,000 fish on hand just prior to opening day," Leaburg Hatchery manager Tim Wright Tim Wright may refer to:
Oregon Department of Fish and Wildlife The Oregon Department of Fish and Wildlife (ODFW) is an agency of the government of the U.S. state of Oregon responsible for programs protecting Oregon fish and wildlife resources and their habitats. officials were able to make up some of the loss by juggling production schedules and allotments at other hatcheries and by purchasing 38,000 trout from a private hatchery.
But the bottom line is there will be fewer hatchery fish available to catch in area waterways during the 2003 season.
"The overall numbers will be down about 30 percent or so," said Jeff Ziller, the ODFW's district fish biologist in Springfield.
As a result, fishing "might be a little bit more of a challenge" this season, Ziller said, adding that "most people are probably not going to notice the difference.
"Instead of catching three fish, you might catch two," he said. "It's certainly a drop, but not a total waste of time, either."
In the McKenzie River, for example, a total of 6,572 trout are scheduled to be released today between the mouth of Blue River and the head of Leaburg Lake. Another 2,075 fish were released Wednesday in Leaburg Lake. Normally, the pre-opener releases would number 9,500 and 3,000 fish, respectively.
Even with only a fraction of the fish available, however, the McKenzie River is bound to fish several times better than it did during the first month of the 2002 season. There was so much "turbidity turbidity /tur·bid·i·ty/ (ter-bid´i-te) cloudiness; disturbance of solids (sediment) in a solution, so that it is not clear.tur´bid
The cloudiness or lack of transparency of a solution. " (suspended silt) in the water then that few people even bothered to try catching trout.
Ziller is predicting a "typical opening day" in local waters this year, aside from the fact that fewer fish will be available.
"The flow is high in both the McKenzie and the Middle Fork Willamette systems," he said. "So the rivers are going to fish a bit slower than in a warmer year. But as long as the water temperature is not too cold, the catch rate should be acceptable."
The reduction in trout stocking does not apply to waters in other ODFW ODFW Oregon Department of Fish and Wildlife regions. So opening day fishing should be normal at popular Cascade mountain Cascade Mountain can refer to:
Those are all reported to be virtually snow and ice free, thanks to the mild winter.
"This is a good year to try fishing the hike-in high lakes," Ziller said. "We did helicopter stocking in 1999 and 2001, so there should be a nice combination of 2-year old fish that are in the 8-, 9-, 10-inch range and 4-year-olds that are 12 to 14 inches."
Coast lakes at full allotment
Meanwhile, lakes in the Florence area are also getting their full regular allotment of fish in anticipation of the trout season opener. As a bonus, many of these lakes are stocked with Adj. 1. stocked with - furnished with more than enough; "rivers well stocked with fish"; "a well-stocked store"

(The coastal lakes are open year-round, but pressure always increases once "fishing season" arrives.)
Anglers are reminded that all Coast Range streams and some in the northern end of the Willamette Valley remain closed to fishing until May 31, to protect juvenile salmon and steelhead as they migrate toward the ocean.
Some Eugene-area waters actually should produce better fishing this year because they will contain more - and bigger - fish than normal.
That results from the ODFW's policies toward fish that have been exposed to IHN, one of the major fish diseases affecting salmonids in the Northwest U.S. and Canada.
Biologists believe that the virus is brought back by fish returning from the ocean and "shed" into fresh water. Other fish then pick it up from the water. The virus poses no threat to humans.
Fish that have been exposed to IHN - even though they no longer test positive for the virus - may only be released in waters where IHN already occurs.

The 300,000 "exposed" rainbow remaining in Leaburg Hatchery's rearing ponds can be used in the lower Mckenzie but not in the McKenzie River above the dam, only 200 yards from the hatchery.
"Even though these fish have tested negative for the past three months, we don't want to take a chance that it (the IHN virus) would spread back down and infect next year's production," Wright said.
Leaburg Hatchery draws its water supply from Leaburg Lake.
Biologists suspect that the virus got into the water supply last summer after being carried above the dam by the large numbers of summer steelhead that "strayed" past the hatchery entrance and climbed the fish ladder over Leaburg Dam.
To reduce chances of that happening again, Ziller plans to trap as many steelhead as possible in the fish ladder this year and "recycle" them downstream.

Other area waters are being supplied with fish from the private Desert Springs hatchery.
Meanwhile, the lower river between the town of Leaburg and Bellinger boat landing is "going to be stocked more than it would have been traditionally," Wright said, because it is one of the few waters in the immediate area in which survivors of the IHN epidemic can be released.
Trout releases in the lower river will not begin until the first week of May, to give out-migrating salmon and steelhead smolts time to clear the area.
Starting at the end of May, the lower McKenzie also will get an allotment of larger (11- to 13-inch) trout that Leaburg Hatchery had been rearing for the upper river fishery.
"The guides have really been requesting some of these larger fish" for the upper river fishery, Wright said.

Salmon outlook optimistic
While trout fishing may be a little slower than normal this year, biologists are expecting a large run of bigger-than-average spring chinook salmon in the McKenzie and Middle Fork Willamette rivers.
About 110,000 salmon bound for the Willamette River Willamette River

The Fremont Bridge, a steel arch with a main span of 1,225 ft (373 m), crosses the river at Portland. were expected to enter the Columbia River this spring, about 10 percent less than year's record-setting run.
"The interesting part of the prediction is that approximately 80 percent of the run will be 5-year olds, which is an unusually large number of very large fish," Ziller said.
One new regulation for local salmon anglers this year is that the section of the McKenzie River between Greenwood Drive boat ramp and the ODFW markers 200 yards below Leaburg Dam has been re-opened to the harvest of adipose adipose /ad·i·pose/ (ad´i-pos)
2. the fat present in the cells of adipose tissue.

That two-mile section "includes some of the best fishing water" for salmon, Ziller said. The section had been closed because biologists thought that stretch of water held mostly wild salmon, which are protected by law.
"People were catching large numbers of adipose-marked salmon all the way up to the dam while angling for steelhead," Ziller said, so the decision was made to re-open the area to salmon fishing.
Another improved fishing opportunity this season is expected to occur in the Eugene-Springfield section of the Willamette River.
The ODFW resumed the "in-town" stocking of summer steelhead in 2001, when 40,000 smolts from Roaring River hatchery were released between the D Street boat ramp in Springfield and Valley River Inn in Eugene.
The first returning adults from that release should begin showing up soon. Based on the results of an experimental release in 1998, those fish are expected to mill around near their release points, where they can be caught by anglers, rather than swimming upstream to Dexter Dam.
The in-town steelhead fishing should be even hotter in 2005. The ODFW increased the total release this spring to 99,600, including about 57,000 IHN-exposed smolts from Leaburg Hatchery that could not be released at their originally intended site.
