Do the Coho Salmon stocked in Cascade lake spawn and die as part of their life cycle as do Coho that go to the ocean?

We have not documented a spawning run/event on the stocked coho. We have seen females with ripe eggs over the years but don't really think they can complete their life history in Cascade. Unfortunately we have stopped using coho in Cascade Res. due to poor returns (the numbers of coho caught by anglers) and budget cuts due to the increasing cost of fish food. We have upped the number of rainbow we are stocking slightly. Thanks for the question.
