The key, though, is biomass per square metre. S Prairie Creek has hosted at least 200K pinks, maybe more. In a 15 mile anadromous zone (more or less) and 20-30 feet wide. What is that? 5% (1/20) of the Skagit ? If so, it would take 4 million to be equal. The MSY goal on Skagit is/was less than 400K. A manager looks simply at numbers and says a million is a lot. Even so, Skagit coho showed a strong response to pinks.

Not to say that those aren't great numbers for the Kenai, but the IPSFC had suggested that, if the Cedar had been a Fraser trib-so they could manage it- that they would have put a million sockeye into it and I don't think the Kenai and Cedar are similar sized.

All that said, on motored streams the salmonids rearing in a stream show and immediate positive response to any increase in deposition with a very steep ascending line from 0 to about 2 kilos, where it then flattens.

In the Shushwap Lake system of the Fraser the resident trout population was sustained by the dominant year sockeye run. The sub-dominant and off years were insufficient to support the trout. They essentially had one good year in four.
