News from the Underground - Transition Tactics
Transition time is a time of disruption and chaos in a musky’s world. Whether it’s the shift to wintering grounds in the late fall, the slide to shallow water haunts in the early autumn, or the most disruptive transition, the move to spawn in the spring, muskies are on the move. But the move isn’t uniform; not all muskies transition at the same time. There will always be multiple effective patterns in play at once. Only anglers who are observant and flexible in their patterning will be successful during a transition. They will be able to lead the pack rather while others must simply follow.
The ultimate transition is the musky spawn. It sets the stage for the first half of the musky season as well as providing musky anglers with a unique opportunity. The opportunity is that it is the one time of year where the smaller males are doing something distinctly different from the larger females in the system. During spawn, the males cruise the shallow spawning grounds for one or two weeks seeking females. A female musky, on the other hand, moves into the shallows only when she is ready to broadcast her eggs. Different females will choose to move in at different times meaning a single female can go from pre-spawn to post-spawn in the span of 24 hours! Weather dictates timing. A cooling trend forces females out to deeper water adjacent to spawning grounds, while a warm-up draws them in and focuses the spawn into a shorter window.
In either scenario, musky anglers must choose their pattern wisely. Is it the beginning of the spawn? If so, most females will be in a pre-spawn pattern: actively feeding near structural elements just outside the spawning grounds. As the spawn progresses, more females will be post-spawn, a time when they are much less likely to feed. Most males will remain concentrated in the spawning grounds throughout this time and may be susceptible to baits that provoke reaction strikes. You’ve got options. Only you can decide when the pre-spawn pattern is off the table due to the remaining number of pre-spawn females being too few. The details of the individual patterns (pre-spawn, post-spawn, etc…) differ from lake to lake as to what locations muskies use and what presentations are effective, so use your own local knowledge once you’ve made your choice.
Whether it’s the spawn or some other seasonal shift, transition time is a time to be flexible. As the season progresses, be ready to exploit emerging patterns while keeping past patterns in the back of your mind. With the spawn transition, that means patterning large pre-spawn females and switching to more active patterns as the entire population progresses through the spawn. Anglers that can do that will put the odds in their favor.
The Bite - Your Musky Briefing
The North
Lakes across southern Minnesota and Wisconsin are ice-free. Warm weather has brought rapidly increasing surface temperatures. Muskies will start spawning in the south within the next week or two, if they haven’t already begun. Northern waters are just starting to open up, but the shift is underway. Snowpack and runoff will accelerate this process over the next stretch of stable weather.
What’s Working Now - Nothing yet. Seasons remain closed. This is transition time, not fishing time. Anglers can start scouting by targeting panfish where allowed.
What You’re Missing - Fish are still compressed. They are staged tightly near spawning areas and current seams. When the season opens, this will not be a wide-open bite. It will be a location-specific window.
The South
Across Kentucky, Virginia, and West Virginia, unseasonably warm weather combined with a lack of spring rains has pushed water temperatures ahead of schedule. Many systems are now post spawn. The shad spawn is driving movement, and muskies are keying in on it.
Muskies are holding near shallow shelves with immediate access to deeper water. They are either extremely shallow during feeding windows or suspended high over open water, moving between zones throughout the day. Spawning activity from a variety of species offer ample feeding opportunities.
What’s Working Now - Fishing both ends of the spectrum. Shallow during active windows, suspended when conditions stabilize. Target shelves, transitions, and areas tied to bait activity.
What You’re Missing - Shallow doesn’t mean it has to be shallow water. Muskies are not static during this time frame and muskies can be found mere inches under the surface but over deep basin and channels.
Iowa and Illinois
Waters in Illinois and Iowa are in a mixed transition. Some fish have spawned, some are actively spawning, and others are still staging. The result is a scattered population with no dominant pattern.
Trolling continues to produce the most consistent results. Smaller baits run at higher speeds along break lines near spawning areas are triggering reaction strikes. Larger fish are holding tight to structure like timber, points, and deeper edges adjacent to spawning zones. These fish are not aggressive and require precise presentations.
What’s Working Now - Covering water with smaller lures at speed. Targeting break lines and structural edges near spawning areas.
What You’re Missing - Fishing slow and blind. These fish are not roaming freely. If you are not covering water or dialing into deeper, structure-oriented fish, you are behind.
Indiana and Ohio
Indiana and Ohio remain in the heart of the spawn, but it is not happening all at once. The spawn is staggered. Some fish are actively spawning, some are pre-spawn, and a few are already post-spawn but inactive.
Pre-spawn females are still the most viable target. They are holding just outside spawning areas, often along break lines, and can be triggered during stable, cool, and overcast conditions. Post-spawn fish are present but largely neutral.
What’s Working Now - Targeting break lines adjacent to spawning areas during stable weather. Focusing on pre-spawn females still holding off the bank.
What You’re Missing - Expecting consistency. Most fish are not feeding. If you are not fishing tight windows and targeting the correct phase, the bite will feel nonexistent.
Underground Intel - Status of the Shield
In the northern reaches of the musky range, winter has a grip this year—and it’s not letting go easily.
Across northwestern Ontario, the arrowhead of Minnesota, and the upper peninsula of Michigan, lakes are still ice-covered with a thick blanket of snow. Walleye anglers in northwest Ontario were still walking out to fish through the ice up to the April 15th close. That alone tells you everything: we’re running behind.
When winter lingers, ice-out dates are pushed into early May. In some years, it compresses even tighter, clearing just days before the walleye opener in mid-May. That kind of delay doesn’t just shift access—it shifts the entire biological calendar of the lake. For musky anglers, that means one thing: expect the spawn to slide later.
A late ice-out forces a later, more condensed musky spawn. That has follow-on effects for early season position, spawn recovery periods, and the musky progression to early summer patterns.
The late winter and significant remaining snow pack (there is still 3 to 4 feet of snow in some areas) is having another effect on lakes in these areas. Lake levels will be restored from their low levels over the last couple of years. More water means more accessible habitat, better distribution of muskies, and a more balanced early season bite.
A late spawn is generally more stable as it is less likely to be disrupted by adverse weather events. This means muskies will get through the spawn more quickly once it starts and more rapidly transition to early summer patterns. The key is to watch the weather. If you plan to fish in the far north in the early part of the season, keep track of the weather starting now and leading up to your trip. Rapid warm-ups can bring the region back into the “normal” timeframe rather than the “late” situation we’re seeing now. Don’t just react, be prepared.

Gear Review - Boss Shad Trident
Let’s get the obvious out of the way right from the beginning. The Boss Shad Trident looks very similar to the Chaos Tackle Medussa: it’s a flat bottom rubber bait with a weighted internal harness and three tails. The price point is similar as well with the regular Medussa retailing for around $27 and the similarly sized Trident on sale for $30. So why have two different baits that look similar?
The answer is simple: they look and act differently in the water. Trident is much heavier, with the medium-sized version weighing in at 11oz compared to just over 7oz for the Medussa. This means that instead of the hang and flutter of the Medussa, the Trident offers a more vertical head drop, similar in some ways to how a Red October Tube would work. At the same time, the Trident’s three tails give more fluttering action on the fall than the tentacles of a typical tube. With some tuning of the Trident harness a gliding, walk-the-dog action can also be achieved. Underground members have found that because of the Trident’s heavier weighting, it is best manipulated with aggressive rips of the rod to achieve maximum triggering in deep water situations. On the other hand, slow sweeps will produce a saw tooth path where Trident ascends at a shallow angle and then falls nearly vertically on the pause.
Trident comes in three sizes: small (9” 8oz), medium (11” 11oz), and large (15” 14oz).
Underground Verdict: A worthy addition to your rubber arsenal that has the coveted “hop” without adding weight.
