I fish a very similar lake that is about 1/3 that size, maybe 25 acres max. I have heard that the lake, more of a big pond actually, has been home to a 13# LM bass, and I actually saw a news paper article with the guy who caught and RELEASED the 13 pounder.
When you get a lake that is rather small and gets alot of pressure, the bigger bass tend to relate to offshore structure most often. If the lake rents boats, rent one, and get yourself a portable fish finder so you can find some good structure next to some deep water, and also fish weed edges next to deeper water. Fish the area with baits that have a natural look to them like swimbaits, jigs, and big worms. Livebait works best at times also, such as shinners, worms, and craws. But try to mimick natural forage as well. I like the idea of giving them something that stands out like a brook trout, thats a good idea. Make long casts to the spot so you don't spook em. Work the area thoroughly, using slow retreives that could take several minutes to get in. Acorrding to Mr Hannon, the best time to catch the good ol' bigguns is in the middle of the day. You want to be as quiet as possible when it comes to moving around the boat. Loud thumps will transmit threw the hull of the boat and into the water spooking the fish, or alerting them to your presence. Make sure you take a camera and a scale and a net will help land the bass too.
According to Fish Chris and some other big bass hunters, the bites are few and far between. Sometimes you will get lucky and catch a big one out of the blue off of shallow structure and/or cover, but from what I understand the big ones usually stick to deeper structure when pressure is high.
Another thing to try is fishing where no one else does. If the lake has thick weeds that would discourage most anglers, tie on a big jig and flip it into the weeds. Makeing sure to have adaquete rod, reel, and line to horse the pigs out, or go to them. The key is finding spots where no one else fishes. Find the spots that receive the least pressure and you will most likely get some big ol' gooduns.
