Fishing tips lake Minnewanka backcountry camping

[Frznrth]

Hi
I'm camping at L9 or L10 for a few days in mid august with some friends. I'm not much of a fisherman but it would be fun to try to catch something - maybe even supper. One friend may be brining a canoe, if not I'll be on the shore.
I have some odds and ends when it comes to rods and tackle. What exactly should I bring if I'm hoping to catch a lake trout? Any chance from shore or do I pretty much need to hope for the canoe?
Thanks for the help
