Chilliwack lake can be a challenge,I have done well getting kokanee on small willow leaf, rubber snubber( soft mouths),10 inch leader,and green or red wedding band with small piece of worm or maggot.Usually I put a 1/2 oz. keel sinker in front of all this .I Start trolling slowly over by the outflow and go up the lake past 2or 3 creeks and work my way back .All the time zig zagging.I have had some success anchoring a safe distance from the outflow and jigging buzzbombs for dollies.If you have downriggers and salt water salmon gear some people use these and go deep for big dollies (200feet sometimes).
