If good water quality is part of your search criteria, Great East Lake and Square Pond are excellent, the others, well not so much.
NH F&G has depth maps and info on many lakes and ponds throughout the state which is a good indicator as to water quality. A Trophic level of Oligo and deep water will have nice water. Anything else you're likely to run into muck bottoms, weeds, and tea colored water.
