Chilliwack hatchery coho are randomly selected for holding and spawning and are not selected for size alone. There are as many small and mid size fish used as larger ones.

Sorry, sarcasm and smart assed tone don't always come through on the net. All sizes spawned, not just big ones. Should be representative of natural size distribution (save for light on jacks).

There are some fry releases to some of the lower groundwater tribs in the lower river these days, and some of the restoration channels mid-river, but not targeted strategic enhancement. Nothing going on in the upper river these days I don't think. The program is focussed on large scale production from the swim-ins still, smolt releases to provide clipped fish to be bonked. Not really aimed at rebuilding any of the small, distinct wild pops. The hatchery does monitor many of the tribe you name, so there is some good data to track wild abundance from year to year in those streams. The wild pop's seem to be holding their own these days.

   Certainly agree there nibs... Buck and I plan to have a look at Centennial this week; may be a shade early for coho but hoping mega chum carcasses are evident!
