New Hampshire may be a small state, but it has some of the most picturesque settings in the northeast. You know those beautiful photos of a lakeside cabin with mountains in the backdrop? That scene could be from a number of lakes in the New Hampshire Lakes Region. This area of lakes is nestled at the base of the White Mountains and contains chains of lakes like Lake Winnipesaukee, Lake Winnisquam, and Squam Lake. These are all good-sized lakes but are any of them the deepest? Deep, cool lakes can provide an ideal habitat for a variety of fish, so is the fishing better in the deepest lakes? Let’s find out all about the deepest lake in New Hampshire.
