I guided at the outpost for 4 years which is about 8 miles north of HIppa. We fished Hippa and Freeman lots. A typical day out there is 15-30 Chinook in the 15-25# range. a really good day and you can be into 50-75+ chinook. As for BIG fish there are small spurts through the season where you can find some decent fish. 30-35# fish are the usual suspects but there are some fish caught int he 40-50# range each year. I used to average 2-3 fish in the low 40's per summer. If your dream is to HOG hunt then this is not the place for you, if you want to catch lots of nice fish its the best place I have ever fished.
The water can be brutal on the west side, totally gross. Avoid July, worst weather (NW winds) and okish fishing....June and August are better.
The are has THE BEST halibut fishing on the entire BC coast. 100# fish are common, 200# fish happen weekly, 300#+ fish happen a couple times a summer
fish big tomic plugs down deep, watch your sounder for pinnacles and bait....
Take a look at the outpost as they have better bigger boats and some pretty good guides, its a small operation only 14 guests.
cheers,
