I use a white tube jig and if ur allowed to use dead bait use some frozen minnow on it the lakes I fish for trout also can’t use live minnows but dead are ok white tube is all I use for trout as for water depth depends on the bait fish that are the lake good way to start is set some tip ups up and see where ur getting bites I’ve caught trout any where from 5 to 60 ft of water depends

Medium action will work for u I fish walleye almost every weekend I catch big ones Littles ones I have medium and medium/heavy rods don’t use ur light rods I have broke a few on walleye cause sometimes they bite hard u don’t have to use anything expensive I have used Walmart rods and work just fine my fav rod I have is a medium action Quontom with 10 lb braid
