The Upper Peninsula has 5,500 miles of state forest roads, with only about 2% closed to ORV traffic.

IRON MOUNTAIN — Snow and ice will soon be in the rear-view mirror, maybe of an ORV.

The Michigan Department of Natural Resources has updated its state forest road maps, which are available at https://www.michigan.gov/dnr/things-to-do/ORV-Riding/state-forest-roads.

Forest road maps are updated each year based on considerations including changing road conditions, data cleanup and input received from residents. Maps show which state forest roads are open or closed to off-road and conventional vehicle use.

It’s important, the DNR says, to stay on these roads to prevent erosion and damage to wildlife habitat.

After the annual road inventory and review, the following will be open to ORVs:

— In the Upper Peninsula, more than 5,503 miles, or about 98% of the total mileage.

— In the northern Lower Peninsula, about 6,109 miles, or about 84% of the total mileage.

— In the southern Lower Peninsula, just over 10 miles, or about 3% of the total mileage.

The DNR reported this Upper Peninsula fishing activity:

— Little Bay de Noc: Ice anglers fishing the upper bay for yellow perch had limited success. There was some fishing activity in deep water in front of Kipling, as well as the “mud flats”. Anglers reported deteriorating ice conditions, with diminishing amounts of good, hard ice, so extreme caution is advised when traveling, as conditions will likely change rapidly as the thaw takes hold.

Keweenaw Bay: Early in the week anglers were able to shore fish from multiple locations along Lake Superior with varying luck depending on conditions and weather. Most successful anglers were able to cast from shore using spinners and spoons and were targeting salmon. Most areas of the lake were open water but with launches still not yet open due to snow and ice pack.

Les Cheneaux: There were few anglers out trying to catch some perch, but the ice conditions were changing daily. There were some intense winds shifting directions and the ice was deteriorating.

Munising: Bay Furnace was open and fishable, however there were still large chunks of ice floating so depending on winds they moved back in.

Marquette: Rainbow trout were slowly running in the Carp River, but no word on any fish species other than brown trout out of the Chocolay.
