from the B.C. Fishing Freshwater Directory and atlas, circa 2002; "Rbs to 3 kg.. Lake Trout, Kokanee, Wkitefish, Burbot. Mostly trolling. elevation is only 1900'.

Take a thermometer with you and find the surface water temp. All Action will be below the surface, so try early morning with a blue/silver Kwikfish K-7 to imitate minnows.
