Yeah, the terminal run size is supposed to be the number of fish that enter the "terminal" area which is generally the bay the river feeds into. That number is, again, "supposed" to include all the mortalities accounted for in the bay and river. This would be escapement, catch, release mortalities, and (at least back in the day) net drop-out. Back in time there was a piece added for pinniped predation on fish in nets. can't speak for what is included now but it tis obvious from the Skok example and maybe even the Nosqually that recovery of wild Chinook is not a value shared amongst the managers.
