Hey!!! The good old serpentine...this is the river where I caught my first ever salmon...My dad took me out there when I was jeez, probably 5-6 yrs old, and we were casting spoons in the lower reaches maybe a mile from the ocean...Well I saw this silvery salmon jumping repetitively as it moved upstream and I just cast that spoon out ahead of that little guy and wham!!!! I had tied into my first ever salmon...I can still remember how quickly my dad ran over when he saw I had hooked one...good times! Ummmm, I don't fish that river really mcallagan, but from what I do know of it by experience, is it can fish well early in the season in the lower stretches....it is a smaller system, with not a lot of flow, so I think spoons or spinners would work best. Not sure it fishes very well late in the season though...like I said it's pretty small and the further upriver you go, the less deeper pools you find...later in the season in that river I would imagine fish would start to accumulate up top, but often these fish are pretty colored by then, or on their redds already, or in like a foot of water and very spooky.
That's all I can add...hope that helps,
