Idaho does have a say they just need to speak up and let it be known. All the tribes even said not to extend because of the low numbers. I think if idaho pushed the issue then things would be different. OR and WA have the dumbest people running the show over there. Simple no fish no fishing... Oh but wait there could be more fish we just dont know so lets fish... Stupidity
Actually you are misled. Idaho has a "seat at the table", but is not a voting member of the Columbia River Compact or the Pacific Fisheries Management Council. they are there as a consultant, and to voice opinion only. Those agencies determine catch quotas, and the individual states determine seasons based on quota.
Unless PMFC and CRC, in partnership with NOAA fisheries, declares an emergency, and adjusts the numbers the states can pretty much do what they want. That being said, Oregon and Washington usually don't try to intercept EVERY salmon or steelhead, because they know where they come from and don't want to eat all their seed corn. They have to let some through to produce the next crop...
