MCHENRY, Md. - The Maryland Department of Natural Resources is urging people to be cautious when venturing onto the frozen surface of Deep Creek Lake near McHenry.
The agency said Friday that snowmobilers, anglers, hikers and cross-country skiers should wear personal floatation devices in case they end up in the water.
The DNR says the ice may be thin in spots, especially near highway bridges. And snowdrifts can act as ramps that may cause sleds and snowmobiles to become unexpectedly airborne.
Snowmobiling is allowed on the lake by those who have obtained permits, available by mail or at local state park offices. Snowmobiles may operate at night if equipped with working head and taillights. Snowmobilers can access the lake at Deep Creek Lake State Park or with permission from private landowners.
