Went here the other day, it has a massive weed infestation. I could see how there's some big fish in there but its really not worth the time. There's just too much junk and too much water to cover.
Be warned.... No one should consume any fish from this water body. It contains deadly levels of the contaminant Mercury!!! http://www.mass.gov/Eeohhs2/docs/dph/environmental/exposure/fish_consumption_advisory_list.pdf
