As far as a non-breeder state record brown my first choice to fish for one would be Wono (lakeville). I have heard of too many reports of monster browns following someone's spinner bait. Since herring are banned, I would drift large silver fallfish caught from some of our smaller brooks.
Second place, only because you can't put a boat on it, is the Saugatuck Reservoir. I have been on two electro-shocking trips there for walleye and the size of some of the fish that come up are scary.
Third place would be an outlier like Lilli where browns come in from stocked brooks. The dam area is a 100' deep and there is now a bubble system down there to improve water quality from what I have been told. Maybe Zoar too. Lake Housatonic gave up a ten pound brown to an electro-shocking trip I was on and it was perfectly marked indicating it either had never seen a hatchery or was stocked long ago in a feeder brook like the 8 mile river as a small fish.
Fourth would be Saltonstall. Bob O. and I graphed huge fish down 80 feet in a 100 feet of water but never could get anything to bite.
Water quality is too poor for Candlewood, Squantz gets over fished, so next on my list is the other glacial lakes that hold over trout and have land-locked alewife herring. These would be East Twin, Ball Pond, maybe Highland and a few lakes in the Eastern District.
JMHO, I am sure there are other hot spots I missed.
