Our conservation dept here in Missouri stocks trout at several area lakes each fall. Most of the trout are around 12" to 14" long, rainbows, with a few browns. They also put a handful of larger trout in also, and I have seen a 21" fish caught. Power bait is what most folks use. Nightcwalers are a close second for bait. I usually try a Panther Martin spinner, or a small Marabou jig. If these don't work I throw a nightcrawler on and try that. Here's something I've noticed about these stocked trout: when they first stock them, the trout will hit almost anything, and are very easy to catch. After some have been caught, say, maybe two weeks after the stocking, they become wary, spooky, and are harder to catch. I like overcast days to fish for them the best. It's a fun way to finish off the season, before the lakes and ponds freeze over for winter. And, if not for our conservation dept stocking these trout, there wouldn't be any trout fishing close to home for me, without driving to the Ozarks, which is three or four hrs away. Do they stock trout in your area? What are your methods for catching them?
