IRON MOUNTAIN — During late August, the Michigan Department of Natural Resources recommends focusing fishing efforts during early morning or late evening hours when fish are more active.

Fish often move to deeper, cooler waters as surface temperatures remain warm. For species like walleye and smallmouth bass, try slow presentations like drop-shot rigs or jigging spoons near structure in 15 to 30 feet of water.

The Wisconsin Department of Natural Resources said Lake Michigan salmon catches were reported around Chambers Island northeast of Marinette. Brown trout and rainbow trout were being caught around the trout bar south of the Menominee River mouth and to the north along the shore in Michigan waters.

The Michigan DNR reported this Upper Peninsula activity:

Little Bay de Noc: Anglers reported fair to good walleye fishing. Anglers fared well south of the Ford River, at Black Bottom, and around Minneapolis Shoals. Anglers trolled crankbaits and casted minnow- or goby-like artificial baits. Yellow perch anglers reported good success using night crawlers and minnows, with some achieving limit catches during the morning hours.

Fairport: Chinook salmon and steelhead continued to be caught. However, average sizes of catch were down, with fewer catches of large adult salmon. Anglers used spoons or flasher fly combos.

Grand Marais: The lake trout bite was great this past week, with boat anglers catching them while trolling and jigging at deeper depths. Coho salmon were also reported caught by boat anglers trolling at shallow depths east of the break wall.

Alger County: Strong inland lake fishing of bass and sunfish continued. Anglers did well near Munising Bay for lake trout, with some reporting of occasional Chinook salmon and coho salmon.

Ontonagon River: Angler reports showed that walleye were caught in fair numbers by those trolling and jigging alike.

Ontonagon/Silver City/Union Bay: Angling efforts in Ontonagon were fair over the past week. Efforts from Union Bay and Silver City were lower in comparison. Inclement weather occasionally limited reasonable lake access. When weather permitted, fishing on the lake was good, with anglers recently reporting catches consisting of lake trout in good numbers. Anglers found success when trolling across a variety of water depths.

Black River Harbor: Angling efforts out of the harbor were low over the past week. Weather conditions occasionally limited reasonable lake access. Reported catches recently consisted of lake trout in fair numbers. Anglers found success when trolling across a variety of water depths.

Keweenaw Bay/ Huron Bay: Anglers reported that lake trout fishing was fair, having had success trolling spoons and flasher flies in 80 to 140 feet of water. Salmon fishing was reported to be more productive.

Traverse Bay/Portage Entry: Anglers reported catching fair amounts of lake trout when trolling spoons and flasher/flies. These were caught in 100 to 150 feet of water, with most fish caught near the bottom. Anglers also reported that salmon fishing had been poor, with only a few anglers seeing any success.
