I have fished in the area a little bit, never camped nor have I done the hike to eagle lake but great scenery, and some decent fishing in the river. Also in the small creek just below the falls at campground you'd be surprised there is some fun little bull trout and Brookies that are always eager to eat
good luck out there and make sure you give us a report on to how your trip went.
P.S me and the buddy saw three Grizzlies up there while fishing the Red deer so just also be aware of them too.
