Channel catfish is only big catfish in Mass. they can grow up to 20 pounds easily. but could grow more farther than that. however, its uncommon to hear that.
So, now, we know its channel catfish that you wanted to chase, it's narrowed lot of search time. Since they are very limited spot that they are in/at.
-Merrimack River
-Connecticut River (your best bet to go this river)
-Charles River
I heard that there are couple of ponds/lakes that contain channel catfish, however, most of people are lip-sealed about this. I am one of them too.
hope it is helpful for you.
