Retriever,
You've got the general idea.  Commercial fish sales are reported on the state fish ticket system (except Quinault, who have their own system, I believe), and the fish buyers send a copy of the tickets to WDFW in Oly.  To speed up the process, port samplers visit each buyer every day during the season and tally the catches and phone,fax, or email them to Oly.  That is called the provisional, or soft, data.  It is sometimes incomplete and therefore subject to revision.  The catches are monitored, usually on a daily basis also, by the harvest managers at WDFW and the tribes.  The feds have a role in setting seasons that deal with inter-state and international fisheries, but leave the day to day management to the state and tribes, so I don't think they monitor the daily catches.
The hatchery managers' jobs are to rear and release fish; they have very little role in harvest management, other than perhaps to report that they aren't getting enough fish back to their hatcheries in some years.
Salmon sport fishing is a management consideration in planning ocean and Puget Sound fisheries.  It is mostly coincidental for freshwater fisheries.  If there are predicted to be harvestable fish left in a run when it reaches the rivers, and after the treaty share is deducted, then freshwater salmon fishing is scheduled.  I don't know that the advance planning by any agency proposes management actions for the purpose of assuring in-river sport fishing.
For most salmon species, the in-river sport harvest, even if it was planned as the number one management priority, would take a very small fraction of nearly every salmon run.  I think it is for that reason that it just isn't on the management radar screen.  The vast majority of the state's salmon harvest is taken commercially, second by salt water recreational fishing, so those are the main management planning considerations.  Lake WA sockeye is the only notable exception that comes to mind.
And since in-river sports harvest is typically last in line (in-river treaty being second to last) these are the fisheries most likely to be shut down as an emergency response when runs come in under the escapement goal - since it's too late to undo the marine harvests that have already taken place.
So if you were thinking that in-river sport fishing is sucking hind t!#, that is why.  If it's any consolation, many of the tribes used to be in that situation, but through court action, they got their fisheries into the pre-season management planning - they attend the north of Falcon hearings and so forth - and so marine fishing is generally restricted to specifically ensure that harvestable salmon make it back to their river fisheries.  And they sometimes get exceptions to fish into the escapement if estimation errors allow over-fishing prior to the treaty fishery.  Of course, two wrongs don't make a right, but that's the management deal that is sometimes cut.
Welcome to late 20th and early 21st century fish management: "how to divy up the crumbs."
Sincerely,
Salmo g.
