When you go through the water-specific regulations in the Freshwater Fishing Regulations Synopsis, look for the fish symbol beside the lake name. The ones with the fish symbols are stocked lakes, so the ones without are not stocked and have wild populations of trout.
Keep in mind that not all stocked lakes provide similar fisheries to Green Timbers, Lafarge, Como and other urban lakes, where success is usually immediate. Many lakes stocked by the Freshwater Fisheries Society of BC are planted with fish at yearling sizes (10 to 50g) and these fish are expected to be targeted after spending one or two years in those lakes. Because these fish have been feeding on whatever food is naturally available in the lake, they are semi-wild and do not fight like those stocked catchable rainbow trout you encounter in urban lakes.
