How do trout move around in a lake, compared to a stream?

The stream logic inverts. In current, food comes to a stationary fish; in still water, the fish must go to the food — so lake-dwelling rainbows and brook trout become cruisers, patrolling repeating beats along shorelines, drop-offs, and weed edges, often surprisingly close to shore in the 1–4 m (3–13 ft) band when temperatures allow. Watch a rising lake rainbow and you can time its circuit: it will come back through on a rhythm, and casting ahead of the cruise path beats casting at the last rise. Lake trout cruise too, but in three dimensions, tracking pelagic baitfish schools through open water. The stream angler's question is "where is the lie?"; the lake angler's question is "where does the path go?"
