7/8wt rod for Alaska?

I'm making my first trip to Alaska at the end of Aug. We will be there
almost two weeks. We plan on fishing for Halibut for a couple of days
then jumping around on creeks, rivers and backwaters in the Anchorage
area.

From what I've been reading it seems fly fishing for Steelhead is
quite ambitious if not as difficult and time consuming as musky
fishing can be. If we are there at an appropriate time is a 7/8 weight
rod sufficient for steelhead? I'm not sure if our timing will be
right for steelhead as I havent checked flow data and such for waters
we will be on, plus I dont really know anything about the area or
steelhead for that matter. My father, who was there less than a year
ago, emailed me some creek names to check out online but I havent
gotten that far yet.

My gut tells me a 7/8wt. is ok but I'm just not sure. I bought the rod
to use for pike and carp fishing but havent gotten around to using it
yet. I usually use a 3-6wt. here in Colorado and back home in Wyoming.

Anyone got any suggestions for creek/river fishing around Anchorage?
How about Pike fishing?

Thanks,
Matt Mika
