See table 3. in this Puget Sound Commercial Regs doc. Look at the Chinook numbers in the Nooksack/Samish row. The numbers are only through the 2007 fishery, however, I cannot believe that they would have changed much from the range presented here. It, at least gives you a scale of the NI commercial catch of Chinook.
