They aren't local, but if you're interested, carvedlakeart.com makes some REALLY cool wooden 3D lake maps. Kinda stumbled on it by mistake. They are pricey, ~$350 for a Winnipesaukee map, but it appears you get what you pay for. Incredible detail and I think they are gorgeous!
Lakesofwood.com also has some beautiful wooden 3D maps. I actually like theirs better but they don't offer a Winni map
