Before
the Ice Age Sockeye ancestors bearing our tribal name, Oncorhynchus
nerka, regularly came from the ocean to Lake Sammamish to find mates
and reproduce in its streams. As it got colder a huge glacier formed
cutting off escape to the sea. Being trapped we had to accommodate to
living our entire lives in fresh water. It was difficult at first but
soon we adapted to feeding on the insects and small invertebrates
living in the lake. Because this food was not as plentiful as in the
ocean our sizes got smaller. Our tribe became content with less travel
time for a life cycle and we were glad to be rid of the perils of
predation by bigger, salt water fish. We became land-locked, adapted
and survived.
We
did retain some of our sea-run traditions such as only living three to
five years and dying after we laid and fertilized our eggs in the
streams. Our short life spans allowed us to make rapid genetic changes
in response to climate changes and food availability. These changes
gave us sufficient numbers for disaster survival, targeted the food in
the lake we needed, and assured that the traditions of the tribe would
continue in our offspring. We specialized and thrived.
After
many generations the Vashon ice sheet retreated and our cousins, the
Sockeye Salmon, started returning to the lake coming up the Sammamish
River after entering Lake Washington through the Duwammish River and
now extinct Black River. We were not that glad to see them because they
were bigger and took over the spawning areas we had reserved for
ourselves. In addition the King and Coho salmon came in to claim more
spawning beds.
To
adapt we divided into three clans, each selecting a different time of
the year in which to go up the creeks to spawn. In this way the
competition for our redds, or gravel beds where we laid our eggs, was
eased and we had more safety during our reproduction efforts. We
adapted and endured.
When
the native humans came they named us Kokanee meaning "red fish" and we
got along reasonably well and provided them with food. The relationship
deteriorated when the immigrant humans came and allowed their farm and
logging waste to enter and change the spawning streams; and then used
us for fertilizer after trapping us while we spawned. It was worse
later when they dumped in their dairy and human waste not only
contaminating the streams but reducing our food supply in the lake.
Humans also restricted our ability to reproduce by putting dams and
culverts in some streams. But we were numerous enough to rebound, even
after our redds were mined away or scoured by flash floods as a result
of heavy water run off from developed areas..
The
worst came when the Federal Government built the Fish Hatchery denying
the Kokanee Clans access to our major spawning area on Issaquah Creek.
Their hatchery is popular bringing in millions of dollars for tourism
and providing some salmon for ocean fisherman. So it persists but we
can not go upstream from the hatchery to spawn, even when they are not
trapping salmon. They plan to remedy this to benefit some Salmon but it
may come too late for us. We can not adapt so we diminish.
Finally,
someone noticed there were not as many of us fresh water fish around so
instead of habitat restoration people chose a policy of stocking and
restocking. That is how we lost so many of our members as prey for
foreign trout, bass and other fish they introduced into the lake. They
even brought in related Kokanee from Lake Kootenay who competed with us
but eventually could not adapt to our special environment and
disappeared. The human's waste changed to include chemical poisons; now
lessening because of governmental concern. No one has heard from the
summer run clan that spawned in Issaquah Creek for quite a while. Our
early run clan has been declared extinct. Only some in the late run
clan have survived.
Good
news has sunk into the lake. The Federal Government passed the
Endangered Species Act that could address and remedy our plight. Our
human friends in the Trout Unlimited, City of Issaquah, King County,
People for Puget Sound, Save Lake Sammamish, Snoqualmie Tribe, and Wild
Fish Conservancy organizations have petitioned the Federal Wildlife
Agency to recognize our peril and help prevent our otherwise certain
demise. These friends filed this request last July citing our genetic
uniqueness and the certainty of our extinction if there is no
intervention. The deadline for response has long passed and there is
none. Another broken treaty. Those few of us left who spawn in Lewis,
Ebright, and Laughing Jacobs Creeks are diminishing. . . as is hope for
our fry.
