I've been floating the Main Salmon for about 16 years and have only caught whitefish in the main part of the fish. But I wasn't trying all that hard. I've seen folks hike up several of the bigger tributary creeks and they say the fishing is good. Chamberlain comes to mind. If the water is high, then I wouldn't waste my time on the main river. I don't think of the Main Salmon for fishing.....now the Middle Fork is another story.
I've only stayed at Ground Hog camp at medium to low water. I know that Whiplash is a real pisser at high water. Seems like a friend told me that he was picked up by jet boat at Ground Hog once for a jet back at really high water.
