Im not sure if everyone else has this link and I am the last to find it or if it is of some benefit to all. It lists bodies of water by town and bottom topography. The site is put up by the Mass Dept of Fish & Wildlife and im not sure how accurate it is but the lakes I have dove, seem to be right on.
