I didn't find this on my own, it was in a thread a day or so ago, maybe posted by midcoast (I can't find where I read it) but it's worth a look by everyone.
www.pearl.maine.edu it has info on lakes and streams throughout the state including species, depth, water quality, stocking (pre and post 1989), and alot more. It's worth the look. A great resource. Maybe everyone here new about it, but it's new to me.
