New Strategy To Boost Crashing Lake Sammamish Kokanee

THE FOLLOWING IS A KING COUNTY PRESS RELEASE

A partnership coordinated by King County released juvenile kokanee into Lake Sammamish after holding the rare native salmon in a controlled hatchery longer than usual to increase their chances for survival. Snoqualmie Tribe representatives released the first few 6-inch-long kokanee from a canoe Wednesday evening after a performing a traditional song.

It is one of several emergency actions that partners are taking to ensure the survival of the native salmon after a sudden, alarming decline in the number of spawners returning to Lake Sammamish streams in recent years.

“We are deploying every available resource and trying new techniques in a united effort to save this little native salmon that has plied our lakes and streams since time immemorial,” said King County Executive Dow Constantine. “It reflects the urgent work we are doing throughout the entire watershed – from the Cascades to Puget Sound – to protect and restore our natural environment.”

The 3,000 fish are the offspring of adult Lake Sammamish kokanee salmon captured during the 2018-19 spawning run, from October through January. Those adult fish were spawned at the Issaquah Salmon Hatchery, where a portion of the young were raised until their release.

Another portion of the offspring from last season’s spawning run were transferred into a private pond along the eastern shore of Lake Sammamish. Fish in both locations were fed and protected from predators with netting.

The wild-hatched siblings of these fish moved from the small streams where they began life buried in a gravel nest along the stream’s bottom down into Lake Sammamish soon after hatching. Once in the lake, the inch-long kokanee faced becoming a meal to larger fish, including non-native predators that have been introduced to the lake, or birds.

Two more-serious threats that young kokanee have to overcome in Lake Sammamish every summer are warm water temperatures and low dissolved oxygen levels. These conditions tend to force the fish into narrow bands of cooler, oxygen-rich water, making them more susceptible to the lethal effects of predators and disease.

Scientists believe these inhospitable conditions could be largely responsible for the sharp decline in native Lake Sammamish kokanee – from more than 18,000 adult fish on the spawning grounds in 2017 to just under 120 this past season.

Executive Constantine announced in 2018 that King County would work with partners to implement recommendations by the Lake Sammamish Kokanee Work Group, a broad coalition that includes residents who live in the watershed, the Snoqualmie Tribe, the cities of Bellevue, Issaquah, Sammamish, and Redmond, the U.S. Fish and Wildlife Service, the Washington Department of Fish and Wildlife, Washington State Parks, Trout Unlimited, Mid-Sound Fisheries Enhancement Group, Mountains to Sound Greenway Trust, Friends of Issaquah Salmon Hatchery, Save Lake Sammamish, Friends of Pine Lake, Friends of Sammamish State Park, and others.

Partners released kokanee after sunset far from the lakeshore so the juvenile salmon are safer from voracious non-native predator fish, such as yellow perch.

In addition to being culturally significant, the native kokanee are important to the bio-diversity of the region. Several scientific studies show that they have a unique genetic signature, having adapted over centuries to the unique Lake Sammamish ecosystem, making them impossible to replace. Genetic diversity makes the natural environment healthier and more resilient, which is particularly important in the face of climate change.

The kokanee run that occurs in November and December – known as “the late run” – is the only remaining native run. Biologists believe the other two runs that historically occurred between late August and early November have been extinct since the 2000s.

Lake Sammamish ‘Warm Water Test Fishery’ Netting Raises Questions

Lee Getzewich had heard that there was some gillnetting going on on Lake Sammamish, a water he’s fished for more than 25 years, and it gave him some pause.

But believing it to be just a “study,” the Issaquah resident decided to hit it earlier this month anyway.

“What we love about it is that it is such a diverse and quality fishery,” Getzewich says of the 4,900-acre King County lake. “We regularly target warmwater species such as bass, crappie, and perch, but we also enjoy the great cutthroat trout fishing, particularly during colder weather.”

When fresh fish is on their menu, yellowbellies and sometimes specks are the target, but that midspring weekday morning, he and his neighbor planned to catch and release cutts and smallies.

“This time of year, when the trout are keying in on the smolts, we regularly catch 20 to 30 cutts in a day, some going over 25 inches,” Getzewich states. “Twenty-seven inches is the biggest I can recall.”

The plan was to cast into the pods of coho just released from the state salmon hatchery in hopes of catching cutthroat preying on the young fish, but after launching at Lake Sammamish State Park’s southeast corner boat ramp they saw nets being deployed off the mouth of Issaquah Creek.

Motoring over to learn more they began talking to the two-person crew. Getzewich says they were shown totes with the previous night’s catch.

“He held up and showed us a sucker fish about 1 pound, but I could see several smallmouth bass and what looked like small crappie in the bin,” Getzewich recalls.

The crew told them that the fish were all being kept so their stomach contents could be studied, and that they were just doing what they’d been told to by biologists.

Getzewich and his neighbor left and fished elsewhere on Sammamish. The day was slow, and they only caught a few small perch and saw some small bass in the shallows at the lake’s north end, where the slough forms.

Afterwards, though, he talked to a buddy with a fisheries degree about what he’d seen and now he isn’t so sure it can be considered a study.

“What I really want to know is, Why is this permitted? Who said this was OK? Why aren’t the people being kept in the loop about this? Where is our DFW?” asks Getzewich. “There is going to be a serious revolution amongst sportsmen if it keeps going.”

ON A MISTY MAY FRIDAY MORNING I decided to go check out things on Sammamish for myself.

With my luck I figured that if any nets were in the water, they would be halfway down the lake, well out of my smartphone camera’s range, so I grabbed my big Nikon and a telephoto lens and headed for the state park.

I parked at Sunset Beach, near a long row of upturned picnic tables, then wandered out on the trail to the mouth of Issaquah Creek, where a wading angler stood in water midthigh high about 30 yards offshore, casting and retrieving a lure.

With his tackle box back on dry land, he kept a wary eye on what I was up to as I peered into the murk for buoys marking strings of nets, but the only ones to be seen were the floats delineating the swimming area. Over on the other end of the string, an angler sat fishing the edge of the lily pads.

Turning around I went back and struck up a conversation with a plunker set up next to a long since fallen cottonwood. He said he was fishing for cutthroat and as we talked some salmon smolts began breaking the surface of the little bay he was on.

He told me that earlier in the day he’d seen a couple larger fish swim by together, but wasn’t quite sure whether they were trout, bass or something else. More and more of the young fish started jumping and as I zoomed in, there were a couple big swirls among the pod.

The angler didn’t really have anything to say about the netting and seemed more focused on trying to catch the fish making those swirls, so as the mist turned to a light sprinkle I left him to it and drove over to the boat ramp.

IT’S BEEN A LONG, LONG TIME SINCE I’VE USED this launch, though back when my dad lived in North Bend we’d put in his aluminum boat and fish it somewhat often.

I remember catching a really, really nice trout one time while we were anchored up just to the right of all the ramps. We ate that one as well as some bass we caught another time.

The last time I was on Sammamish was maybe 15 years or so ago with fellow F&H News staffer Jamie Parks. We hit the other southern corner that early spring day to fish for largemouth then zipped north to smallie waters, and on this morning three bassers were launching two boats.

Moored at the end of the leftmost dock was a net boat.

As he readied his craft, I asked the lone angler if he’d heard about the netting and after initially drawing a blank, he recalled fellow anglers mentioning some being dragged through the water.

The other two gents putting in were far more in tune with what’s been going on and they were not exactly happy about it.

As he swiped through pics on his phone of beautiful — and big — bronzebacks, Chris Senyohl, who operates a fly fishing guide service called Intrepid Anglers, told me that the nets had wiped out one of his best smallmouth spots.

His buddy said I’d just missed the net crew and that he’d seen them lift two largemouth out of their boat.

He said they’d been on the water every day during the work week, which is when he said he prefers to fish Sammamish.

HUNGRY PREDATORS GATHER AT THE SOUTH END OF LAKE SAMMAMISH IN SPRING TO SNARF DOWN JUST-RELEASED SALMON SMOLTS LIKE THESE COHO THAT SPILLED OUT OF THE BELLY OF A TROUT CAUGHT BY FAUSTINO RINCON. (FAUSTINO RINCON)

SLIGHTLY DAMP I CALLED IT A MORNING, drove past BMC West, where I worked for awhile after college loading lumber, fighting with customers over bent boards and drawing cartoons at the back gate, and headed in to my office.

I started working on this story on May 9, the day that the Muckleshoot Tribe sent out a notice showing they were intensifying their test fishery for warmwater species on Lake Sammamish and, coincidentally, the day that Lee Getzewich and his neighbor had fished there.

The notice showed that the effort could be expanded from two boats to three, with the maximum number of 3.75- to 6-inch-mesh gillnets tripling, from eight to up to 24.

Now, that doesn’t necessarily mean that that happened, but the regulation restated that the nets could be fished from 6 a.m. Monday until 6 p.m. Friday, by which time they’re to be removed for the weekend.

I left a voice mail on the Muckleshoot Fisheries department’s phone not long afterwards, but it hadn’t been returned as of Tuesday morning, May 28, so to figure out what’s going on, you have to zoom in on a couple different documents.

Probably the most important source of information is inside the LOAF — the 2019-20 List of Agreed Fisheries that was concurred to and signed on April 22 by the Washington Department of Fish and Wildlife and Northwest Indian Fisheries Commission coming out of the annual North of Falcon season-setting process.

The LOAF essentially lays out all of Western Washington’s salmon fisheries in salt- and freshwaters negotiated between the state and 20-plus tribes, and in the back are a number of appendixes.

Pages 83 to 85 detail what is termed the “2019-2020 Warm Water Test Fishery” to collect data whether a directed fishery on spinyrays in the Lake Washington watershed could be “commercially viable” while also avoiding impacts on Endangered Species Act-listed salmon and steelhead.

“Using large mesh gillnets will eliminate impacts on age-0 Chinook and any potential steelhead smolts migrating out to sea,” the project description states.

The Muckleshoots also state they want to “instrument” walleye they catch with acoustic receivers to see how much their range overlaps with outmigrating coho smolts to target those areas in the future.

Another document, the tribe’s 2016 watersheds report, adds context: “A recent tribal study found that fewer than 10% of coho smolts released from the Issaquah Hatchery survived their freshwater migration to Puget Sound. The Lake Washington basin’s miles of docks, bulkheads, rip-rap, warm water, and the many native and exotic fish predators favored by those degraded conditions are likely at fault.”

Their announcement that they were increasing netting efforts roughly coincided with this month’s release of millions of coho as well as Chinook smolts — the fish I saw jumping in the mist.

SALMON SMOLTS LEAP OUT OF THE LAKE, PERHAPS JUST HAPPY TO HAVE BEEN RELEASED FROM THE NEARBY ISSAQUAH HATCHERY OR MAYBE ATTEMPTING TO FLEE PREDATORY FISH. (ANDY WALGAMOTT)

THIS IS THE THIRD YEAR THE MUCKLESHOOT test fishery has been going on — it initially included Lake Washington — and it follows 2015’s unexpected discovery of more than a dozen walleye, including an egg-dripping 13-pound hen and six males close by her.

To paraphrase a retired state fisheries manager, whomever recently put walleye (and then northern pike) in the system was no friend of fellow anglers who’ve chased warmwater species for decades, but the Muckleshoots are more blunt; they use the word “criminal” to describe the act.

Besides its many native stocks, crappie have been in the watershed the longest, in Lake Washington since at least 1890, followed by largemouth in 1918, and smallmouth there and in Sammamish since sometime in the 1960s, perhaps earlier.

Lake Washington is ranked as one of the top 100 bass lakes in the entire country by Bassmaster magazine, and is 16th best in the Western U.S.

Local clubs regularly hit it and according to WDFW tournament fishing records, the average bass landed there during the last 10 years weighed 2.22 pounds; the average on Sammamish was 2.31 pounds.

As popular as they’ve become, the times they are a’changing. The plight of the orcas and their primary food has put a target on the fins of spinyrays.

Earlier this month Gov. Jay Inslee signed Second Substitute House Bill 1579 which primarily — and finally — gives WDFW some actual teeth to protect shoreline habitat for Chinook and their forage fish.

It also contains a clause that the Fish and Wildlife Commission must now “liberalize bag limits for bass, walleye, and channel catfish in all anadromous waters of the state in order to reduce the predation risk to salmon smolts.”

The latter idea came out of the governor’s Southern Resident Orca Task Force’s recommendations last year and it echoes current regulations on the Columbia.

Limits were dropped on the three species in the big river system several years ago following pushing from federal fishery overseers.

How WDFW and the commission interpret “liberalize” and “anadromous” has yet to be determined (no limits? using SalmonScape?), but the bill goes into effect July 1 and will surely include Lakes Sammamish and Washington.

I’m no biologist, but my bet is that bass really don’t have much to fear from sport pursuit because of current support, Northwest anglers’ general preference for other fish on the table and conservation practices, and health advisories.

In other words, it’s a feel-good measure, though with more and more efforts throughout our region to supress or kill off nonnatives like lake trout, northern pike — even rainbow trout — this also feels like it could be a potential inflection point.

ONE GROUP THAT ESSENTIALLY SUPPORTS the netting on Lake Sammamish is FISH, the Friends of the Issaquah Salmon Hatchery, a nonprofit that leads tours at WDFW’s most-visited production facility and does a lot of youth education with third- and fourth-grade students.

But the organization has also been moving into the realm of advocacy lately, said Larry Franks, its vice president and longtime salmon and steelhead angler.

“We’ve tried to identify things that benefit fish,” he said.

Franks, who retired from Boeing and also has a fisheries degree from the University of Washington, said that despite 2.5 million Chinook being released from the hatchery, last year saw a return of just 1,800 adults, or .07 percent survival.

Part of that is the productivity, or lack thereof, of the North Pacific, as well as harvest by all fleets, but primarily low smolt survival, just 8 to 10 percent from Issaquah to Shilshole Bay, outside the Lake Washington Ship Canal, he said.

“The deck is stacked against them. Our goal is to have better returns,” Franks said.

One problem, he said, is the increasingly narrow band of Lake Sammamish that salmon must swim through between too-warm surface waters and its anoxic depths.

The other is the predators that sit and wait in the zone for the smolts to swim through, then chow down.

Franks believes that the number of warmwater species in the lake and their populations have grown, and that that is impacting salmon outmigration and thus returns that are “dropping precipitously.”

“We’re of the position these are cause and effect, not correlation,” he said.

He acknowledges the growth of the state bass fishery and that smallmouth and largemouth anglers are every bit as dedicated as he is to chasing salmon. He believes that WDFW doesn’t want to piss off spinyray anglers either and is afraid to act — at least without more hard scientific data.

“It comes down to a choice: If you want to retain bass fishing, it’s going to be hopeless, in Larry’s opinion, to save Chinook,” Franks said.

A state staffer close to the situation didn’t want to be quoted for this story, but if official WDFW comments during its recently held Walleye Week on Facebook are any indication, they will be managing salmon and steelhead waters for salmon and steelhead first, and spinyrays where it makes the most sense.

(WDFW is also in the third year of a Lake Washington Ship Canal study to determine abundance and diets of smolt-eating fish there.)

Another option might be trucking Issaquah Hatchery’s smolts and Franks said experiments are ongoing. But anecdotally, it didn’t produce bigger returns last year, though more results are expected this year and next.

That leaves removing the predators, like the Muckleshoots are doing.

“We’re supportive of efforts that would increase the Chinook return,” said Franks.

AS FOR HOW MANY FISH ARE BEING GILLNETTED in Sammamish, the LOAF — that marine area by river by lake rundown of agreed-to fishing state and tribal seasons and constraints — contains a short statement that caught my eye.

It says that with “the potential for interaction with the public,” the Muckleshoots propose providing monthly reports on their test fishery, including gear used, where it was fished and for how long, to the National Oceanic and Atmospheric Administration.

So I asked NOAA for that information, and a week and a half later a federal spokesperson provided me with summaries of catches in March and April for what are known as Zones 7 and 8, the northern and southern halves of the lake.

According to the figures, nearly 2,850 fish were caught and removed from the system during those two months, roughly 60 percent of which were native species, 40 percent nonnatives.

Just over 53.5 percent of the overall catch (1,525) was comprised of largescale suckers, a native fish, followed by introduced smallmouth bass (577) at 20 percent and fellow transplant black crappie (258) at 9 percent.

Other species caught include:

Northern pikeminnow (146), 5 percent, native
Brown bullhead (126), 4 percent, nonnative
Cutthroat trout (85), 3 percent, native
Largemouth bass (78), 3 percent, nonnative
Peamouth chub (24), 1 percent, native
Common carp (11), .4 percent, nonnative
Yellow perch (10), .3 percent, nonnative
Hatchery-origin Chinook (3), .1 percent, native
Mountain whitefish (3), .1 percent, native
Hatchery-origin coho (1), .03 percent, native
Rock bass (1), .03 percent, nonnative
Walleye (1), .03 percent, nonnative

No rainbow trout or natural-origin Chinook were caught, NOAA’s catch breakout shows.

Kokanee, which are at low levels in the lake but also a pelagic, or open-water, fish were not listed in the catch tally.

Under the terms of the test fishery, if three wild steelhead are netted, the effort will be shut down immediately. In the LOAF, the Muckleshoots state that there is a “very low to zero” chance of any turning up, and if one did, they suggest it would probably be a Green River stray.

Gillnetting is set to run through June 15, and I am interested to see what turns up in the catch during the final seven weeks of the program, what with the release of all those coho and Chinook smolts into the system — will the catch percentages change?

The test fishery is also scheduled to resume next January through April.

SOMETHING LARRY FRANKS SAID STUCK WITH me after our talk:

“It’s a thorny problem.”

Understatement of the century.

As a salmon angler, like many other Northwest sportsmen these days I’m howling that something, anything needs to be done about predators — be they sea lions, harbor seals, Caspian terns, cormorants or piscivorous fish — to get more smolts out and more adult fish back.

That means there’s no way I can support killing pikeminnows in the Columbia, northern pike everywhere in our region, birds at the mouth of the river, and pinnipeds at Bonneville and Willamette Falls without also giving the thumbs up to removing smolt-eating fish in Lake Sammamish.

At the same time, my inner spinyray angler is revolted by what feels like a targeted attack on a fish I like — I literally nearly went bankrupt trying to write a story inspired by catching a huge smallmouth on the Grande Ronde — one that’s widespread across the Northwest and is a great entry-level fish that’s easy to catch.

I’m all for hatcheries, but, holy sh*t, here’s a species that doesn’t require the world’s largest fish production infrastructure to perpetuate in perpetuity, plus they’re ready-made for climate change.

Yet as a Washington native, tell me why our fisheries have to be exactly like what you can already find in Michigan, Arkansas, Pennsylvania, Ohio, Quebec, Tennessee, Iowa, New Jersey, Minnesota, New York, Ontario, Missouri, the Dakotas, New England, Illinois, Wisconsin, Indiana? We’re not the Old Northwest, this is the Pacific Northwest, home of silver fish, not green ones, and proud of it.

Then again, I’ve also read my King of Fish: The Thousand Year Run of Salmon — with all the problems that our kings, silvers and steelies face, you tell me that smallies and their Midwestern and Southern cousins aren’t what’s going to come out of the other end of things here as the sole survivors.

The utter mess we have made of this region obliges us to do our best to fix it.

At what cost, pray tell?

So as you can tell, I’ve got mostly mixed feelings here.

I do, however, have a problem with the illegal release of walleye in Lakes Sammamish and Washington, and northern pike in the latter. Doing so was among the most asinine, destructive and disrespectful things perpetrated on the watershed since the Great Glacier smothered it. I’ll tar and feather the a@$hole bucket biologist(s) myself.

The comanagers aren’t talking, but I’ll tell you what, I wouldn’t doubt for a second that those crimes were among the tipping points that set their test fisheries in motion. And now everybody but the guilty are paying.

A BLUE HERON WAITS FOR PREY TO SWIM BY. MANY THINGS PREY ON LAKE SAMMAMISH’S SALMON. (ANDY WALGAMOTT)

I’M DOUBTFUL THERE WILL BE A “COMMERCIALLY VIABLE” fishery for bass in Lake Sammamish or elsewhere in the system some day, but I could be wrong.

I just hope that the netting shows whether targeted removals of smolt predators at select times and places is worthwhile for increasing salmon survival and expanding harvest seasons — while also preserving native and nonnative fish and fisheries that aren’t going away any time soon.

I’m willing to put a nickel down that while introduced exotics like the bass do have an impact, it’s mostly limited to the two months or so that the young coho and Chinook are transiting the system, and that like over on Lake Washington with sockeye smolts, cutthroat and northern pikeminnow are the actual primary predators.

Again, I could be wrong, but I’d love to learn what is in the stomachs of the thousands of fish the Muckleshoots pull out of the lake this spring. I’d hate to see this all go to waste.

Perch Derby Highlights Plight Of Seattle-area Kokanee Stock

Another yellow perch derby will be held on Lake Sammamish, this one on Saturday, May 18, part of a larger effort to recover the lake’s kokanee population.

THE 2ND ANNUAL LAKE SAMMAMISH PERCH DERBY WILL BE HELD SATURDAY, MAY 18, WITH CASH AND PRIZES TO BE AWARDED FOR ANGLERS WHO BRING IN YELLOWBELLIES LIKE THIS ONE. (ANDY WALGAMOTT)

It follows on an initial derby put on last September by Trout Unlimited, who say that catching yellowbellies will help the metro water’s landlocked sockeye. Juvenile perch compete with kokanee for zooplankton, key forage for the native fish.

Headquartered at Lake Sammamish State Park in Issaquah, the derby begins at 8 a.m. and runs till 1 p.m. 

“There will be adult and kid divisions with prizes awarded to the person catching the longest perch, the heaviest perch, and the heaviest 25 perch, and also a bonus prize for the largest pikeminnow caught by registered anglers,” reads a TU event announcement.

Tickets are $30 for adults, $15 for kids, and all proceeds go towards recovering Sammamish kokanee.

Those in the King County lake have been struggling for decades as the surrounding area has urbanized and water quality has declined. Despite efforts to prop up the population in recent years, there has been an alarming decline in spawning numbers. Less than 20 were counted in tributaries in fall 2017, prompting an emergency response from county officials.

TU was among the groups that in 2007 petitioned the U.S. Fish and Wildlife Service to list the stock under the Endangered Species Act, but in 2011 the feds declined to do so, saying it wasn’t an independent population.

According to state biologist Aaron Bosworth, yellow perch were introduced into Sammamish in 1915, and though it’s unclear who put them there, it came near the end of the era when the U.S. Fish Commission was moving Eastern gamefish into Western waters.

These days, efforts are being made to get them out of the lakes, or limit their impacts to young salmonids.

During last fall’s derby, 636 perch weighing 146 pounds were weighed in, with Jeff Stuart accounting for nearly 19 pounds alone, most of anyone.

He also had the longest in the adult division, a near 11½-incher, while in the kids division, Wesley Mehta weighed 7¾ pounds of perch overall and Carson Moore brought in both the longest and heaviest perch.

Sponsors include Washington State Parks, King County, Bass Pro Shops, the Snoqualmie Tribe. For more info, see lakesammamishkokanee.com/perch-derby.

Tourney Catch Data Shows Central Washington Waters Shine Bright For Bass

Updated 9:10 a.m., March 27, 2019 at bottom with additional details on the impact of bass retention liberalizations on the Columbia.

Draw a straight north-south line from Oroville to Plymouth in Central Washington and it will touch the four waters producing the fattest tournament bass in the Evergreen State.

WDFW reports that the average weight of largemouth and smallmouth caught in contests at Lake Osoyoos, Moses Lake, Potholes Reservoir and the John Day Pool was 3.34, 2.74, 2.57 and 2.45 pounds.

TOURNAMENT BASS ANGLERS FISH A LAKE WASHINGTON SHIP CANAL BAY DURING AN EVENT LAST MAY. (ANDY WALGAMOTT)

The agency posted the rundown on its Facebook page today, and it also might help noncompetitive anglers figure out where to go catch bucketmouths and bronzebacks.

In listing the top 18 waters, WDFW said that it had crunched the weights of 146,124 bass caught during events held across the state over the past decade.

Four other Central Washington waters are also on the list:

5 Bonneville Pool, 2.36 pounds
7 McNary Pool, 2.24 pounds
10 Lake Chelan, 2.15 pounds
15 Banks Lake, 1.84 pounds

Further east, far Eastern Washington posted four:

11 Long Lake (Spokane), 2.13 pounds
13 Box Canyon Reservoir, 2.05 pounds
16 Lake Roosevelt, 1.81 pounds
18 Little Goose Pool, 1.33 pounds

But the Westside has its share of lunker lakes too:

5 Bonneville Pool, 2.36 pounds (we’re calling it a liner for two regions)
6 Lake Sammamish, 2.31 pounds
8 Lake Washington, 2.22 pounds
9 Lake Whatcom, 2.21 pounds
12 Silver Lake (Cowlitz), 2.11 pounds
14 Riffe Lake, 1.86 pounds
17 Lake Tapps, 1.67 pounds

As part of receiving a permit to hold a tournament, organizers must report how many fish were caught during the event and how much they weighed.

That Osoyoos stands so far above the other waters may (or may not) be due to the relatively few are held there, if WDFW’s 2019 fishing contest calendar is any indication. It lists just two this year on the Okanogan River reservoir that stretches from Oroville into British Columbia, so a couple events with relatively hefty catches might have pushed its average up. Or not.

A pair of Grant County lakes are particularly popular with bassers; Potholes and Moses will host dozens of events this year.

WDFW’s rundown comes as a bill in the state legislature would require the state Fish and Wildlife Commission to liberalize bag limits on bass, as well as walleye and channel catfish, in all anadromous waters of Washington to reduce predation on salmonid smolts.

That would essentially extend the current no size/bag limit regulations on the Columbia and Snake systems to places like Lakes Washington and Sammamish, where the Muckleshoot Tribe has been conducting warmwater test fisheries in recent years.

There have been no restrictions on how many or what size bass you can retain on the Columbia above Tri-Cities, the Snake and their tribs since 2013, and the Columbia below Tri-Cities since 2016.

A month or so ago I asked WDFW biologists if they’d seen any effect of that in terms of bass as well as similarly affected walleye and channel catfish, but they couldn’t say as they don’t conduct creel or population samples specifically for those species, though walleye and bass are monitored by ODFW through the northern pikeminnow program.

However, the tourney bass data does offer an unexpected window.

In responding to feedback on its Facebook post yesterday, WDFW said, “Average weights of bass weighed in tournaments have not changed significantly in the Columbia River Pools. The average since 2016 is slightly higher than the 10-year average.”

Angler Calls In Illegal Release Of Tilapia Into Lake Sammamish

An angler still can’t believe what he witnessed at Lake Sammamish last week: a woman dumping live tilapia off the docks there.

BRAD HOLE REPORTS THE TILAPIA WERE STILL BREATHING FIVE HOURS AFTER THEY WERE RELEASED. (BRAD HOLE)

While apparently not a brazen act of bucket biology, it still serves as a reminder about how not to dispose of unwanted nonnative species.

Brad Hole was preparing to launch his Hobie to fish for one of the King County lake’s other species when he saw a woman roll a cooler down the dock and tip its contents in.

“At the time I didn’t know they were fish. She went back to her car and got another wheeled cooler and dumped that one in,” Hole says.

“I asked her what she dumped. ‘Tilapia,’ she said,” he recalls. “I educated her that it’s illegal to dump fish into the lake — especially nonnative species. I even went on to tell her about the Louisiana crayfish that were dumped years ago.”

As the woman left, he took down her license plate, and later WDFW Sgt. Kim Chandler arrived on the scene.

“Three of the fish she dumped were laying on the bottom,” says Hole. “I was already out fishing but managed to snag a couple off of the bottom. Doubt they can survive in the cold water.”

Tilapia are a warm-water species and it’s unlikely they would have survived in the lake, but Hole says that even five hours after their release the ones he snagged were still breathing.

“People often think they are doing a kindness to animals by releasing them into the wild, but, in many cases, those animals are not adapted for our climate and perish,” said Justin Bush, executive coordinator of the state Invasive Species Council, in a press release. “What seems like a humane action often leads to suffering in the end for the animal. In addition, wildlife that can survive may damage Washington’s natural resources and cost thousands of dollars in cleanup costs.”

According to the Washington Recreation and Conservation Office, $137 billion — with a b — is spent annually across the country trying to manage the impacts of invasive species.

Northeast Washington is on the front lines of one such a fight as state and tribal managers work to knock down northern pike numbers in Lake Roosevelt before they get into the anadromous zone downstream of there.

Lake Sammamish doesn’t have any northerns, at least that we know of, but illegally introduced walleye have been captured there.

Hole says that he was able to identify the tilapia dumper for WDFW.

“The subject who released the fish was contacted and given a written warning,” says Rachel Blomker, an agency spokeswoman.

But Hole still can’t believe someone would do that.

“She seemed surprised that she was doing anything illegal,” he says.

RCO offered these tips for getting rid of unwanted fish:

  • Donate unwanted plants and animals to an accredited environmental learning center, aquarium or zoo. You also may contact your local pet store, which might be willing to accept them. Please instruct them to never release them either.
  • See the Invasive Species Council’s map of “Don’t Let it Loose” partners who might be able to help you re-home your unwanted pet or give you advice on how to care for them.
  • Seal all plants in a plastic bag, freeze for at least 24 hours or until frozen solid, and then place them in the trash. Do not compost the material.
  • Contact a veterinarian or pet retailer for guidance on humane disposal of live animals, as a last resort.

Catch Perch, Help Save Imperiled Sammamish Kokanee At Derby

A yellow perch derby will be held on Lake Sammamish tomorrow, Saturday, Sept. 15, part of an effort to help out the lake’s landlocked salmon.

“They are abundant and are predators of the endangered kokanee salmon at certain life stages,” say organizers of the event being put on by Trout Unlimited. “The derby will not only help to reduce the number of perch in the lake but will educate anglers about kokanee salmon and the ongoing work to improve the watersheds and health of Lake Sammamish.”

Headquartered at Lake Sammamish State Park in Issaquah, the derby begins at 7 a.m. and runs till 2 p.m.

Prizes include $200 each for longest and heaviest perch, and heftiest overall catch (maximum: 25 fish).

There’s also a youth division with $50 gift certificate to a sporting goods retailer for the same three categories.

More prizes from the Snoqualmie Tribe and local businesses will be given away as well.

And according to TU, all proceeds will go towards recovering kokanee.

Those in the King County lake have been struggling for decades as the surrounding area has urbanized, and despite efforts to prop up the population in recent years, there has been an alarming decline in spawning numbers.

Less than 20 were counted in tributaries last fall, prompting an emergency response from county officials.

TU was among the groups that in 2007 petitioned the U.S. Fish and Wildlife Service to list Sammamish kokanee under the Endangered Species Act, but in 2011 the feds declined to do so, saying it wasn’t an independent population.

Yellow perch are a popular sportfish. According to state biologist Aaron Bosworth, the species was introduced into Lake Sammamish in 1915, and though it’s unclear who put them there, it came near the end of the era when the U.S. Fish Commission was moving Eastern gamefish into Western waters.

These days, efforts are being made to get them out of the lakes, or at least limit their numbers and impacts to young salmonids.

After perch were illegally stocked into Eastern Oregon’s Phillips Reservoir, state officials launched a gillnetting campaign and released piscivorous tiger muskies into the lake to try and recover the once-vaunted rainbow trout fishery.

In Northeast Washington, after a “startling increase” in perch numbers at previously clean Curlew Lake, locals organized a “Perch Purge.”

Tickets for the Lake Sammamish derby are $20 for adults and $5 for kids, $30 and $10 if you register on site at the state park tomorrow.

Dramatic Dropoff In Lake Sammamish Kokanee Population Spurs Action

THE FOLLOWING IS A PRESS RELEASE FROM KING COUNTY

A work group created by King County is taking emergency and long-term action to counter an alarming downward trend of Lake Sammamish kokanee, a native salmon population that appears closer than ever to extinction.

County and state biologists counted fewer than 20 kokanee in the most recent return, five years after more than 18,000 spawners returned from Lake Sammamish.

“The native kokanee salmon – important to our history, our culture, our environment – are facing new challenges that potentially threaten their very existence,” said King County Executive Dow Constantine. “Together with our partners, we will take new, immediate actions to protect the iconic species and continue our long-term work to create healthier salmon habitats throughout our region.”

Biologists are investigating a number of possible factors that led to the most recent dramatic decline, including the increasing frequency and magnitude of harmful high temperatures and low-dissolved oxygen conditions during summers in Lake Sammamish. They are also beginning to study the compounding effects of parasites, bacteria, and related diseases during these events.

The Lake Sammamish Kokanee Salmon Work Group – which King County created in 2007 to help guide strategies to protect the unique species – recommended a series of immediate and long-term actions:

  • Use specially designed traps to capture returning spawners for the hatchery program
  • Use the latest technology to protect the unique genetic stock of Lake Sammamish kokanee
  • Release young salmon into Lake Sammamish in the fall of 2019, after the lake’s temperature cools and oxygen levels rise
  • Reintroduce kokanee salmon to additional creeks in the watershed, reducing the risk that a flood or drought in a single creek will wipe out the entire run
  • Lead technical work to understand and guide strategic actions to address the underlying factors that are threatening the kokanee population

For the past decade, the Kokanee Work Group – an alliance of tribal and local governments, state and federal agencies, landowners, and residents of the watershed – has worked together with the shared goal of a healthy, stable kokanee population.

The Work Group continues to make progress, with more than 18,000 spawners returning to Lake Sammamish during the 2012-13 run. But scientists are concerned that the new challenges have the potential to wipe out the remaining kokanee population unless immediate action is taken.

Working together to restore healthy salmon habitats throughout King County

King County and other land managers are continuing their habitat-restoration work that will improve the health of the kokanee salmon population. The ongoing work includes:

  • Removing barriers to healthy habitats, such as replacing fish-blocking culverts along the East Sammamish Trail and Parkway so salmon can move up and down streams
  • Planting thousands of trees and shrubs that provide shade and cover for salmon
  • Increasing public awareness and education to reduce stormwater pollution
  • Partnering with the Issaquah Hatchery to help secure remaining kokanee population

In addition to being culturally significant, the native kokanee are important to the bio-diversity of our region. They have a unique genetic signature, having adapted to the unique Lake Sammamish ecosystem, making them impossible to replace. Genetic diversity makes the natural environment healthier and more resilient, which is particularly important in the face of climate change.

(KING COUNTY)

The kokanee run that occurs in November and December – known as “the late run” – is the only remaining native run. The two other native runs that historically occurred between late August and early November no longer occur because those kokanee have been extinct since the 2000s.

The Lake Sammamish Kokanee Work Group active membership includes the Snoqualmie Tribe, each of the five local jurisdictions in the Lake Sammamish watershed, the U.S. Fish and Wildlife Service, the Washington Department of Fish and Wildlife, Washington State Parks, Trout Unlimited, Mid-Sound Fisheries Enhancement Group, Mountains to Sound Greenway Trust, Friends of Issaquah Salmon Hatchery, Save Lake Sammamish, Friends of Pine Lake, Friends of Lake Sammamish State Park, and residents who live in the watershed.

Hatchery Coho OKed For Retention On Sammamish

Anglers will be able to keep hatchery coho they catch in Lake Sammamish, smolts that apparently decided against going to sea in 2016.

WDFW put out an emergency rule-change notice early this afternoon allowing the retention of fin-clipped silvers under landlocked salmon rules.

 

That means they count towards your trout limit.

Minimum size is 12 inches, and the regulation stays in effect through May 31.

Kokanee and Chinook must be released.

According to biologist Aaron Bosworth, the residualized coho are believed to have been from last year’s release.

He says he’s not sure why they didn’t head for the ocean, but it’s happened in the past, he’s heard.

Cutting an e-reg allows anglers to legally remove them from the lake, Bosworth says.
