And that is the rub - there can be no exceptions to the state wide moratorium!

The fish are trapped and hauled around a series of 3 impassable falls. Both the chinook and bull trout are included in the listed ESA/DPS for those speices.

While robust resident trout populations are often assocaited with salmon populations it is usually with pink, chum, and/or sockeye salmon. This fish return in large numbers bring lots of marine nutrients to the system as well as dislodging substantial numbers of eggs due to their mass spawning habits as supplying incredible numbers of fry in the spring. The salmon population above Sunset is dominated by coho (20 to 50,000 per year). This aren't typcially mass spawners. In addition will the pink, chum and sockeye leave the river shortly after hatching the coho and some of the chinook spend at least a year in the river (about 8% of the coho 2 years) rearing before leaving the system. These parr are direct competitors with the trout parr. In this case I would say that the trout population is limited by the salmon (coho) abundance.

Remember this reach of the river has been managed with selective gear restricitions and a 14 inch minimum size limit. Such management in a trout water would be expected to produce a decent biomass of trout.
While there are trout found in many of the runs and pools and some of them are pretty nice (14 to 20+ inches) they are nealry as abundant as I would expect.
