It depends on the fishery,but most of the time it's like this.
Winter steelhead (Brats) 10lb / 8'6"
Winter steelhead (Nates) 12lb / 8'6"
Summer steelhead (Brats) 8lb / 9'6"
King's bouy 10 & Ocean 30lb main / 40lb leaders.9'
Fall king's & Coho in the rivers 20 to 25lb main
8'6" to 9' rods.
Pretty much use different line size and rods' for every situation.It's almost endless.
Good luck,
