CONCORD - New Hampshire Fish and Game Department officials urge outdoor enthusiasts to exercise caution when enjoying winter activities near the ice at all time, especially now early in the winter season. Fish and Game Col. Kevin Jordan said, "With uneven temperatures, some areas may look safe, but don't count on it. We are urging people to check the ice thickness before you go out onto any frozen waterbody." Because of the unpredictable ice conditions, it is not advisable to drive vehicles onto the ice, Jordan said. Those on foot should carefully assess ice safety before venturing out by using an ice chisel or auger to determine ice thickness and condition. Continue to do this as you get further out on to the ice, because the thickness of the ice will not be uniform all over the waterbody. Though all ice is potentially dangerous, the U.S. Army Cold Regions Research and Engineering Laboratory in Hanover offers a "rule of thumb" on ice thickness: There should be a minimum of six inches of hard ice before individual foot travel, and eight to ten inches of hard ice for snow machine or All-Terrain Vehicle travel. Keep in mind that thick ice does not always mean safe ice. It is possible for ice to be thick, but not strong, because of varying weather conditions. Weak ice is formed when warming trends break down ice, then the slushy surface refreezes. Be especially careful of areas with current, such as inlets, outlets and spring holes, where the ice can be dangerously thin. Tips for staying safe on the ice include:
Ice safety is also very important for snowmobilers. Don't assume a trail is safe just because it exists; ask about trail conditions at local snowmobile clubs or sporting goods shops before you go.
