IRON MOUNTAIN — Temperatures are expected to plummet before Michigan’s archery deer opener Thursday.

A surge of Arctic air will push temperatures into the 50s on Tuesday and Wednesday, while Thursday’s predicted high is 48, according to the National Weather Service. Temperatures next weekend are expected to be 10 to 20 degrees below normal.

Wisconsin archery hunters have connected on a handful of bucks, while the bear season has been very productive, said Fay Whisler at Whisler Outdoors in Florence, Wis.

“Trout fishing is still steady,” she added, pointing to a 22-inch brook trout among the catches.

“They’ve been catching some perch and bluegill — some nice perch,” she said. Crappie minnows were the preferred bait for bluegill.

Musky anglers were taking advantage of the recent warmth, but were coming away mostly with time spent outdoors.

On the lower Menominee River, anglers were after walleyes, sturgeon, trout, and salmon, according to the Wisconsin Department of Natural Resources. Sturgeon fishing was popular below the Hattie Street dam in Marinette, with anglers reporting their success has been after dark fishing from both sides of the river.

Perch fishing continues to be popular on the Peshtigo River out of the County BB launch in the town of Peshtigo, Wis.

The Michigan Department of Natural Resources reported this Upper Peninsula activity:

— Keweenaw Bay: Boat anglers were marking fish, but the bite was tough. Those trolling picked up a little bit of everything, but no big numbers of fish. Surface water temperatures were in the mid to high 50s. If we get some cool rain and the right winds, fish may start showing up a little more concentrated.

— Marquette: Boat action for lake trout was still good near Shot Point and from the White Rocks to Granite Island. Only a few coho were caught. On the Dead River, smaller pink salmon were reported near the dam. On the Chocolay River, a few coho and smaller brown trout were caught. Fishing was slow on the Carp River.

— Little Bay de Noc: Walleye anglers reported fair catches near Kipling when trolling a crawler harness around the reefs. Best catches were at dusk in 14 to 20 feet. A few large fish were caught south of the Ford River when trolling the “Fingers” and near Round Island in 10 to 20 feet. Several good perch catches were reported around the First and Second reefs in 8 to 24 feet with crawlers. Shore anglers in Rapid River took fair catches on crawlers. Bluegills and bullhead were also caught. This is a good place for kids to fish. A few shore anglers were looking for salmon along the Escanaba River, but no fish had been caught.

— Manistique River: The numbers are down from last year, but anglers are catching both Chinook and pink salmon. Brown trout were also caught. The best area for boats is near the high dam spillover and rapids (small boats only). Shore anglers are fishing between the “Bass Hole” and the dam.

— Munising: The few boats trying for coho reported poor catch rates. Some caught the occasional splake. Shore anglers also reported slow fishing. For those looking to do a color tour and go fishing, the leaves have started to turn, and some areas were close to 50% color.
