Advice on Canadian walleye

[Deouss13]

Im up there with the wife and three young kids 13-10-6.. All love fishing..but not catching fish while on a fishing trip with NOTHING else to do is beyond TOUGH.. Not knowing any contours, i fished along grassy drop offs early and late and didnt catch much of anything.. There are rocky points extending into the lake at different areas and i tried to throw some jigs into those areas, drag worms along edges while back trolling.. Again..not alot of luck..the i ly time we caught fish last trip was when a storm was about to hit..walleye started biting for 30 min.. I had to race to shore bf i was swallowed up by the monsoon that was about to hit.. After the storm the next day they went dead again...

Also back troll small rapalas along weed beds. Any running water? Feeder creeks, etc.

Did not see any creeks but ill google earth the lake and look.. I wonder about a three way swivel with a sinker or bottom bouncer and run a lure??
