Elkins / New London, NH

One of New Hampshire’s deepest lakes in terms of average depth - as well as one of the windiest - Pleasant Lake offers a stunning view of 2700-foot Mount Kearsarge. But the lake often exhibits fickle freezing patterns due to its depth, strong winds, and large flocks of ducks. Occasionally the center of the lake stays unfrozen until March. When the lake does freeze, it’s the location of a machine-groomed skating trail accessible from behind the Elkins Post Office. The trail can be anywhere from 1 to 3 miles long depending on ice conditions.

10’ average depth

It’s rare to find good ice on Winnisquam. This can be attributed to three factors:
1. It’s a big lake, and it’s one of the deepest in the state, both in terms of average depth and maximum depth.
2. It has a lot of current, especially at the south end, where it receives all of the outflow from Lake Winnipesaukee, as well as treated sewage from the city of Laconia.
3. It’s surrounded not by mountains but by rolling hills and suburban development, so the climate tends to be warmer.
Lake access points in Belmont and downtown Laconia are not recommended due to strong currents and thin ice. Safe access is sometimes possible at Ahern State Park in Laconia or the Sanbornton Town Beach on Dr. True Road.
