News from the Underground - Deep Patterns

While most anglers target the shallows post-spawn, savvy musky hunters look to deeper water as surface temperatures hit the low-to-mid 60s. During this window, two distinct deep-water patterns emerge: the “off the break bite” and the “open water bite.”
The Off the Break Bite
As panfish like bluegills and crappies stage near break lines to spawn, muskies position themselves further out, pinning forage schools against shallow sand or gravel flats. Look for schools of panfish near the surface over 10–20 feet of water, usually a cast or two away from main structures like points and bars connected to shore. Position your boat on the break line casting out, or sit well into the deep water and cast back toward the structure. If your lure spooks a school of panfish, you are in the right spot. Focus on lures that emulate the size and profile of panfish.
The Open Water Bite
Simultaneously, insect hatches draw pelagic forage like ciscoes, shad, and perch into deep mud basins. Like lions following a herd of antelope, muskies shadow these schools. This pattern often holds the largest fish in the system, but the vastness of the habitat requires specific tactics.
Option 1: Trolling The goal with trolling is maximum coverage. Use the maximum number of legal lines and spread them wide with planer boards. Start with a speed of around 4.0 mph. Speed is your friend; only slow down after long periods of inactivity. If you get bit, consider increasing your speed further. For lure depths, early-season open-water muskies typically hold in the top 5 feet of the water column. Keep your lures shallow, with a maximum depth of 10 feet.
Option 2: Electronics & Casting To cast open water efficiently, you must use side imaging and/or live sonar, treating forage schools as "moving structure." To locate fish, motor through the basin at 3–4 mph until you find forage. Look for groups of muskies relating to a single forage school rather than lone roamers. Drop waypoints on fish and schools, then use your trolling motor to stay within casting range. Forage is mobile; keep your electronics active to track the "structure" as it moves.
On smaller bodies of water, these patterns often merge. When a basin sits within a few casts of a panfish spawning flat, muskies may exploit both forage sources simultaneously.
While the rest of the fleet is "flogging the shallows" with small bucktails, heading deep provides you with an edge. By targeting the forage—whether it's panfish on the break or pelagic forage in the basin—you position yourself to catch the biggest muskies in the lake while others are stuck in the weeds.
The Bite - Your Musky Briefing

Wisconsin
The weather in the northern part of the state has been unseasonably cool with regular below freezing temperatures overnight. Water temps have been steady in the mid- to upper-40s on most lakes for the past two weeks. Pre-spawn patterns are in play from the middle part of the state heading north. Small males are available in the shallows, but larger females are being caught near deeper structure adjacent to spawning bays on normal-sized muskie baits that start and stop. In the south, water temperatures have warmed into the low-60s and muskies are starting to recover from their post-spawn funk.
What’s Working Now - For pre-spawn fish in the north, small twitch baits in the shallows can trigger, but normal-sized baits on adjacent structure have been tempting larger females. In the south where weeds are up, small bucktails on weed edges have been productive in the warmest bays.
What’s Out - There’s a mix of different patterns in play right now. If you are focusing on one bite or type of structure and nothing is happening you are not being flexible enough.
Minnesota
Water temperatures in the southern part of the state or trending into the low-60s. With warm air temperatures projected for the next week, expect an on-time progression. Meanwhile, the northern part of the state is still a bit behind. Walleye anglers there reported slower than normal action for last weekend’s opener due to walleyes still being engaged in the spawn. Very few incidental muskies were observed.
What’s Working Now - Updating your electronics! The season is still closed, but it’s time to get fired up for the musky opener on June 6th!
The South
Water temps are in the high-60s and low-70s after some much needed precipitation. Reservoirs are still not moving as they would be this time of year. There’s not been enough rainfall to allow for significant dam releases. Muskies are treating the reservoirs like natural lakes. Structure is paramount since current has been removed from the calculation. Swimbaits, small bucktails, and dive-and-rise baits have been successful around structure.
What’s Working Now – Swimbaits with oversized paddles tails and small profiles have been dominant around structure.
What’s Out – The rattle trap bite in the shallows is fading now, giving way to more traditional presentations.
Iowa and Illinois
Water temperatures are stabilizing in the low 70s as weather patterns settle. Post-spawn muskies have transitioned to points and are holding tighter to developing weed cover. Crankbaits remain the primary producers.
Success currently hinges on "matching the hatch"—specifically gizzard shad on lakes that have them. Fish are committing to a tight 6”–8” profile, with the Drifter Tackle Believer, Livingston Head Hunter, and Smoker Tackle SS Shad leading the pack. Pay close attention to daily preferences between straight and jointed actions.
What’s Working Now - Wind has been a key factor for musky positioning. Wind-blown points and weed lines are holding the active fish. Even on flat calm days, the previous day’s wind makes all the difference.
What’s Out - While we are on the cusp of the blade bite producing, that pattern has not fully emerged. It’s ok to check it over the next week or so, but do not lean on bucktails as your main presentation.
Western Ontario
Many lakes are just now losing their ice, just days in advance of the walleye opener this weekend (May 16th). The progression is still well behind schedule. With cool weather expected to return this weekend, there is no indication that the seasonal progression will catch up to the calendar. Still, with more than five weeks until musky opener, there is still time for the situation to change.
Northeast US
Water temps are heating up and so is the bite in the northeast. We’re seeing water temperatures into the 60s and the fish in all stages. Shallow jerk baits and twitch baits like the Slammer 5” Fatty Minnow and 4” Phantom gliders have been key. During cold snaps, fish have been tight to bottom on the first break line. Jigging presentations have been most effective for fish hugging bottom.
What’s Working Now - Small baits that trigger reaction bites are working on many types of structure right now. Keep your head on a swivel and be ready to change your positioning when things go quiet.
What’s Out - Leave large lures in the box for the time being. Big baits are occasionally moving fish, but follows aren’t eats.
Eastern Canada
The rivers of eastern Canada are still recovering from major flooding and high flow rates. Expect high water to dominate the early season patterns when the season opens in June.
Underground Intel - The Fractured Spring

There’s a certain comfort in calling it a “late year.” You hear it at the ramps and in bait shops: late ice, late spawn, late fish. It sounds predictable, as if the season simply slid back two weeks on a calendar. But in the north, late ice doesn’t just delay the system—it fractures it.
What you’re walking into for the early season isn’t a clean pattern; it’s a lake that hasn’t decided what it wants to be yet.
Three Timelines on One Lake
In a normal spring, the transition is linear: ice melts, water warms, and fish move in an orderly progression. In a late year, that timeline compresses, and the order falls apart.
Some fish push up fast, seeking protected, soft-bottomed bays to spawn and leave in a hurry. Others lag. Main lake fish or those in wind-exposed areas hang in an "in-between" stage, uncommitted to moving. You end up with three seasons overlapping on a single body of water: fish that are post-spawn, fish currently spawning, and fish that haven't even started. That’s not a pattern; it’s chaos.
The Problem of Unstable Water
Cold water is predictable. Unstable water is not. The primary challenge of a late spring is how fast conditions reset. A few warm afternoons might push a shallow bay forward, but a single night of north winds can hit the reset button.
Most anglers chase warmth, but what actually matters is stability. Many areas will warm up only to give that heat right back. Fish feel that volatility, and they react by staying tentative.
When "Good" Water Isn't Ready
You’ll eventually idle into a bay that checks every box—shallow, protected, and stained—yet feels empty. In a normal year, that water is money. In a late year, you’re simply ahead of it. The weeds aren’t up, the bait hasn’t settled, and the biological system hasn’t caught up to what your eyes are seeing. It’s frustrating because it feels like you’re missing something, but usually, the lake just hasn’t synced up yet.
Fishing Reality, Not Memory
If this trend holds, the early season in the north won’t be about finding "the spot." It will be defined by:
Short Windows: Brief moments where things line up and fish move, rather than all-day bites.
Disjointed Pockets: Finding one bay that feels like late May right next to one that feels like early April.
Ghost Follows: Fish that show themselves once but won't repeat the behavior elsewhere.
The biggest mistake is trying to force the lake into a version of itself that isn't there yet. Don't fish memories or expectations of what the muskies should be doing. Instead, look for the part of the system that is furthest along. Seek out shorelines that hold their warmth overnight and water that maintains its color.
Late springs don’t reward certainty; they reward attention. Your first few trips won’t give you the whole picture, but if you stop looking for a pattern and start looking for progression, it won't feel random. It’ll feel like a start.

Musky Lure Review - Spanky Baits Violence

The Violence is Spanky’s new topwater offering for 2026. Built with Spanky’s typical top-notch components, the bait is ready to battle even the biggest muskies. The rotating head is solid resin, and the through-wire construction is made from the same 0.062 wire that Spanky Baits uses for its bucktails. At 10” long and 3.9 ounces, it is a large solid bait.
The tail of the bait consists of a wire shaft, a double flashabou skirt, and two treble hooks. It is constructed much like a bucktail, with the trailing hook kept in-line with heat shrink and the leading hook zip-tied to the shaft to keep it aligned as well. The tail swings free on a split ring attached to the rotating head, minimizing the leverage a musky has when shaking its head out of the water. In fact, the lure seems designed to maximize hooking and holding capability, mimicking the best properties of bucktails.
With a standard wire leader, the weight of the rotating head does tend to hold the bait underwater at low to moderate speeds at the beginning of retrieves. At moderate speeds, the head remains low in the water (another sign of a good-hooking surface bait), giving the bait a unique guttural chug. At higher speeds, the lure has the familiar pop-pop-pop of more standard tail prop baits. In the figure eight, Violence tracks like a bucktail and is equally at home on the surface and submerged.
Underground Verdict: While many will be most comfortable with Violence retrieved at high speed, its strength is what makes it different: its low chugging action with a moderate retrieve, its heavy-duty hardware, and its attention to hooking fish and keeping them hooked. But at moderate speeds, a high rod tip is required at the beginning of your retrieve to draw the bait to the surface.
