Muskie anglers don’t always agree on the best ways to catch the fish of 10,000 casts. Variations in today’s lures and tackle mean there’s more choices than ever to support multiple muskie techniques and presentations, any of which can decrease that 10,000 number to something a lot more reasonable. That said, at least three of the most successful muskie anglers in the Upper Midwest do agree on something: the month of September is one of the best times to be on the water.
Ply September’s Shallow Weeds
“The pre-turnover period that occurs from the last week or so of August and continues pretty much throughout September has become my favorite time of the whole muskie season,” said Minocqua, Wisconsin-based muskie hunter, outdoor communicator, and fishing promoter, Steve Heiting. “During this time, we will see and catch many of the biggest muskies of the entire year. It generally starts when water temperatures cool to below 70 degrees, but really ramps up between 65 to about 58 degrees. After that, turnover is on the verge of happening and this particular bite is mostly over. I’ve succeeded fishing this pattern throughout Wisconsin, Minnesota and Ontario, and understand it also works just fine in southern reservoirs — just a little later in the year.”
Heiting said the pattern is a muskie caster’s dream because the fish—including those giants that lived in the deep lake basin all summer—move shallow, and they’re there to feed.
“Muskies can be very individualistic, so they may not all move at once, but the ones that are shallow will be biting. They will use shallow sand flats, weeds that are still green, or rocks,” said Heiting, who adds that the thickest, greenest coontail and cabbage beds are among the best places to start the hunt. “Wind helps, especially on rock spots, but it isn’t necessary to trigger fish,” Heiting continued, adding that the biggest muskies will almost always use spots that have deep water nearby. “In dark water systems, I generally position my boat in six feet of water and fish shallower, and in clear-water systems I may hold the boat in about 10 feet and fish shallower, but it depends on the layout of the spot.”
He said it’s important to cover water to hunt active fish.
“Big bucktails with double 10 or double 9 blades, like those offered by. Muskie Mayhem Tackle, and topwaters like the Bucher TopRaider or Lake X Fat Bastard, are staples at this time,” Heiting advised. “A big minnowbait such as a 10-inch Slammer Minnow or a jerkbait like a 10-inch Suick Muskie Thriller will come into play when the muskies don’t want to chase bucktails or topwaters.”
Because Heiting is exclusively using big baits for big fish right now, almost every rod in his boat is rated heavy power, and since figure 8’s are so important, these rods are all 8-foot, 6-inch or longer.
“Let the longer, heavy-power rod do the work of casting the big baits, and it will also do a better job of taming big muskies,” he said. “St. Croix’s Mojo Muskie 8-foot, 6-inch heavy-power, fast action model is terrific for this application, but any 8-foot, 6-inch or 9-foot heavy-power St. Croix rod will work great.”
The only time Heiting will use a medium-heavy power rod this time of year is in sunny, post-frontal conditions, when he downsizes to bucktails with double 7 blades like a. Mepps Muskie Flashabou.
“A medium-heavy power rod just makes casting these lighter, smaller lures easier,” he said. “Any 8-foot, 6-inch or 9-foot medium-heavy St. Croix rod is a great choice.”
Heiting most often uses reels with a more powerful 5.3:1 retrieve ratio at this time of year.
“High-speed retrieves are less important now than in summer, and a mid-range reel allows you to fish slowly or fast, depending on what the muskies want,” he said. “Load your reel with 80- or 100-pound braided line to provide insurance when fishing around heavy shallow cover or structure.”
The Moon Plays in September
Professional fishing guide, Rob Manthei, has been plying the fabled muskie waters of Northern Wisconsin’s Vilas, Oneida, and Iron Counties his entire life. He agrees that the month of September is a magical time. Like Heiting, Manthei targets big fish in shallow weeds.
“September for me is all shallow weeds, weed edges, and flats,” Manthei said. “I pattern muskies around particular lakes that are ‘blooming hard’ prior to the fall turnover and key in on water between five and 12 feet deep. Water temps start dropping with the cooler nights, which brings fish that have been spending most of their time out deeper into the shallows.”
Manthei says moon phases can be especially important this month.
“Underfoot, overhead, full, and new moons are special times,” he said. “I really like west or south wind directions, and dark, gloomy days are my favorite.”
Manthei looks to double-bladed spinners as his go-to bait throughout much of the pre-turnover period, which he typically burns over shallow, green weeds.
“Large-profile and typically dark to all black color combinations work really well. The dark colors show up best in the bloomed-up water, and 95% of strikes are within 10 feet of the boat or during figure 8’s,” continued Manthei, who opts for longer, 8-foot, 6-inch to 9-foot, 6-inch rods for this reason.
“The new. Mojo Muskie 9-foot, 6-inch medium-heavy, fast, telescopic model is a fantastic rod for all but the largest blades, and the 9-foot, 6-inch, 9-foot, and 8-foot, 6-inch heavy-power Mojo Muskie models, Legend Tournament Muskie, Premier Muskie, and Legend Elite Muskie models are all good choices for double 9’s and 10’s. Muskie Mayhem JR Double Cowgirls with double 8 blades are my favorites,” Manthei continued, “But, I also hand tie a custom spinner with double fluted 9’s that I love, too. I always run 80-pound Seaguar Threadlock braid as my main line.”
Manthei said the shallow weed bite lasts until water temperatures dip to 60 or 62 degrees.
“Once that happens, we pray for wind to mix the lakes and complete the turnover quickly so we can move into the next phase of fall muskie fishing.”
Don’t Overlook Topwater
Owner of LakeX Lures and LakeX Guide Service, John Kleczewski, of Park Falls, Wisconsin reiterates much of what Manthei and Heiting have to say about September’s shallow weed bite.
“Weeds are starting to die off now, so look for the greenest ones available. When the fish slide up shallow, a Fat Bastard paired with the Mojo Muskie 8-foot, 6-inch heavy-power, fast action rod will cover water fast and call muskies out,” he said. “We are also throwing the. LakeX XToad on the 9-foot Premier Muskie extra-heavy ‘Rubber Rod’, as well as running blades over the tops of the weeds.”
Kleczewski shares Manthei’s affinity for the. Mojo Muskie 9-foot, 6-inch MHFT (telescopic) rod.
“I personally like to bulge my blades over the weeds with some speed at this time of year, and this rod is perfect for 7’s, 8’s and even 9’s,” he said. “That extra length not only helps increase casting distance, but excels in executing effective, long, and deep figure 8’s.”
Whether you’re a hardcore muskie hunter or a more casual angler looking to increase your chances at connecting with more or larger Esox masquinongy, all of our experts agree that right now is among the best possible times to be on the water. If your fishing time is limited, plan to hit the lake during gloomy, overcast days around the full or new moon, and gear up with the specific lures and rods necessary to fish shallow, green weeds and other shallow cover and structure.
When asked about the best windows to be on the water this month, Heiting says: “Give me a still, humid, slightly-foggy morning when I can still wear shorts but need a hoodie for comfort, water temperatures around 62, and a full moon which will set in the early morning, and it won’t be long before my net smells like a muskie.”
Follow the forage shallow this month and you’ll find the predators, but don’t wait: these bites typically last throughout September and into early October and end once the first, serious cold snaps drive fish to deep structure.
