Yeah, no native falls but natural spawners... maybe considering the amount the tribe dumps in to fish on. The tribes have subsistence fisheries on the springs, targeting the N Fork (Kendall) fish but who knows what they're intercepting, including other species (steel) when fishing below the confluence. There are definitely more N Fork springs than S Fork but the majority are hatchery brood stock (clipped and/or tagged) with few naturally returning spawners. But as I'm told it takes time (decades) for brood stock programs to show any colors. Skookum hatchery (Lummi-run) used to have a decent S Fork broodstock program going but cut it a while ago for BS reasons and now are struggling to reestablish it using captured juveniles and raising them to adulthood at Kendall. Stop by Kendall and ask to see the progress... very interesting. I would venture to say that there are currently well under 50 spring chinook returning to spawn in the S Fork, some of which are strays... N Fork springs? hatchery falls? who knows.
