Actually, I think the Watcher you are referring to was from the Westgate. "...the pool is up to the wall at Westgate. The Watcher in the Water took Oin." If it is from the Westgate, then it could be referring to the thing that tried to grab Frodo at the gates of Moria (portrayed as an octupus type creature in the movie). As to where, when, and how he originated, he probably had been around since the beginning (similar to ungoliant). Other than that, I have no idea. Anyway, Just a thought...
