Oncorhynchus nerka, our kokanee salmon in Lake Sammamish, is a threatened native species with greatly reduced numbers spawning in streams feeding the lake.
Most of their historical spawning areas are now denied by barriers or degraded as a result of land development.
Until recently, Lake Sammamish kokanee have not been included with other salmon species in conservation measures and have been low in profile for public concern.
For the past several years, an effort of the environmentally concerned and governmental communities adjacent to Lake Sammamish have participated in defining the problem, setting goals and taking action to address the threatened loss of the kokanee.

For 5 million years, an ancient class of salmon has been swimming in lakes and streams once connected to the Pacific Ocean. They are kokanee, a small species of freshwater salmon.
Kokanee live in Lake Sammamish and spawn in its creeks. Their scientific name is Oncorhynchus nerka. It is a combination of hooked-nose in Latin together with a complex, Latin-Polish name for red salmon. They share the nerka name with their ancestral, but genetically distinct, sockeye salmon. The name, kokanee, comes from the Okanagan-Salish language and means red fish.
Lake Sammamish kokanee embrace their red fish name when they return in November through January to their birth creeks to spawn. In the lake, they are mostly silver with small scales, not spotted like trout, and have a distinctively forked tail. At spawning time, the bodies of males turn a bright red with green heads and a hooked nose. The females’ bodies turn red with a faint green stripe.
Spawning pairs seek gravel beds in the same streams where they were hatched. In these streams, they move gravel around making redds in which the female lays eggs to be fertilized by the ever-attendant male. The eggs incubate in the gravel redds for three to four months during which an alevin with an egg sac forms. Alevin then absorb the sac and mature into kokanee fry. The fry wait for a stream temperature of about 52 degrees and a dark night to leave their gravel beds and make a run downstream to the lake.

Conservationists plodded along rain-soaked creek banks last autumn to collect mature Lake Sammamish kokanee salmon in a soggy slog and pluck fish from a handful of streams to preserve the fading species.
The groups responsible for the salmon run restoration effort plan to return to Laughing Jacobs Creek on April 19 to release minuscule fry — a sign of success for the local, county, state and federal agencies entwined in the preservation program.
The annual kokanee fry release celebrates the ongoing push to restore the declining kokanee population in Lake Sammamish and launches Earth Day observances in the area. The community is invited to participate and learn about the salmon species — a landlocked cousin of sockeye — and the preservation program.

Lake Sammamish kokanee salmon supporters raised almost $10,000 last month to protect the disappearing fish species.
Friends of the Issaquah Salmon Hatchery and Coho Café organized a March 16 fundraiser to net dollars for a kokanee restoration program.
The sold-out event raised funds from ticket sales for a reception at the Watershed Science Center on the hatchery grounds and a silent wine auction benefit.
Matt Baerwalde, a Snoqualmie Nation representative, presented a $5,000 check to FISH Executive Director Jane Kuechle for the kokanee spawning program.

The message from groups toiling to save a fish species from extinction is simple and stark: SOS, for Save Our Salmon.
Kokanee S.O.S. is a planned fundraiser organized by Coho Café and Friends of the Issaquah Salmon Hatchery to aid the diminishing Lake Sammamish kokanee salmon population. The restaurant and the nonprofit organization are planning a March 23 fundraiser to benefit kokanee restoration efforts.
“This possible extinction is literally happening right in our own backyard and if a community as educated and affluent as King County cannot turn this critical situation around, then I’m not sure there is hope for any people to protect a dwindling and important resource,” said Heather VanDorn, Coho Café Catering manager.

Population is in decline, but local stock is not ‘distinct’ from other kokanee
Federal officials decided dwindling Lake Sammamish kokanee salmon do not qualify for protection under the Endangered Species Act, prompting a chorus of disapproval from local officials.
The species’ decline concerned U.S. Fish & Wildlife Service officials, but did not merit the fish being listed under the act. The agency announced the decision Oct. 3.
The once-abundant kokanee declined in recent decades, perhaps due to construction near creeks, increased predators, disease or changes in water quality.
In recent years, the number of salmon in the late-fall and early-winter run has dwindled to fewer than 1,000 in some seasons. Kokanee return to only a handful of creeks — Ebright, Laughing Jacobs and Lewis — to spawn. Scientists estimated the total 2010 run at 58 fish, including the 40 kokanee spawned at the Issaquah Salmon Hatchery in a last-ditch effort to save the species.
The decision came after the agency spent four years to review the Lake Sammamish stock’s health.

The unsettled economy is threatening the chinook-salmon spawning program at the Issaquah Salmon Hatchery.
The state Department of Fish and Wildlife has proposed reducing the number of chinook eggs collected at Issaquah and other state-run hatcheries to cut costs as the state faces a $1.4 billion shortfall.
The proposal recommends for the local hatchery to collect about 1.3 million eggs — about 1 million fewer than hatchery crews planned to collect.
“Issaquah is not a sole target in this,” said Doug Hatfield, hatchery operations manager for the region encompassing Issaquah. “This is a decision that the agency put forth to distribute this impact throughout Puget Sound and on the coast.”

Summer is on the wane and autumn starts Friday, so the time is right for salmon to complete a final journey from the Pacific Ocean to Issaquah Creek and other King County streams.
Though the salmon return so far is generally smaller than the pre-spawning season forecast, opportunities abound to see migrating salmon in the Lake Washington, Cedar River and Lake Sammamish watershed as chinook, sockeye, coho and chum complete a long sojourn.
King County calls the event Salmon SEEson.
Salmon can soon be spotted at parks, along trails and at events sponsored throughout the Puget Sound region. In many cases, naturalists can help visitors spot the fish and learn about the salmon life cycle.

Creeks leading to Lake Sammamish could serve as staging areas in the years ahead for a bold plan to restore salmon habitat.
The regional Lake Sammamish Kokanee Work Group has proposed 11 projects in Issaquah and Sammamish to restore habitat for chinook salmon — a species protected under the Endangered Species Act — and dwindling Lake Sammamish kokanee salmon.
The once-abundant kokanee has declined in recent decades, perhaps due to construction near creeks, increased predators, disease or changes in water quality. Scientists estimated the total 2010 run at 58 fish, including the 40 kokanee spawned at the Issaquah Salmon Hatchery in a last-ditch effort to save the species.
The proposed projects range from colossal — such as rerouting Laughing Jacobs Creek through Lake Sammamish State Park — to small — adding plants in the Lewis Creek delta, for instance.

The long process to add the dwindling Lake Sammamish kokanee salmon to the endangered species list inched ahead July 12, as the U.S. Fish & Wildlife Service agreed to make decisions soon about the salmon species and more than 700 animal and plant species under consideration for federal protection.
Under a legal agreement between the agency and environmentalists, the Fish & Wildlife Service is required to decide by the end of the year whether the Lake Sammamish kokanee proposal should proceed.
Taylor Goforth, a spokeswoman for the Fish & Wildlife Service in Lacey, said the agreement does not change the plan, because the agency intends to release a decision during the same timeframe.
“It’s still under review and we’re aware of the deadline and we plan to make it,” she said.
Local environmental groups, governments and the Snoqualmie Tribe petitioned in 2007 to list the landlocked salmon species as endangered.
