Vermilion Lake Fishing guide

Like many large lakes, Vermilion is dealing with aquatic invasive species. Zebra mussels are now considered established, based on the presence of larvae, even though adult mussels have not been documented. Rusty crayfish are also well established, particularly in East Vermilion, where they have altered habitat by reducing aquatic vegetation. Finally, spiny waterfleas may be encountered especially when trolling. For anglers, this means potential changes in fish location and an increased responsibility to prevent further spread. Cleaning boats and gear is not just a rule-it's part of protecting the fishery.

2026 Angling Outlook

Lake Vermilion stands out as a destination where anglers can target multiple species in one trip-and realistically succeed at several. Whether you're after a meal of Walleyes, a trophy Muskie, or steady bass action, the lake offers a wide range of experiences. Lake Vermilion is composed of two major basins, East Vermilion (east of Oak Narrows) and West Vermilion (west of Oak Narrows). Each basin is slightly different in terms of habitat and fish communities. Lake Vermilion's two basins can create distinct fishing experiences. West Vermilion generally offers higher fish numbers across several species, making it a strong choice for action and consistency. East Vermilion, on the other hand, often produces larger fish on average, appealing to anglers focused on size. The opposite is generally true when it comes to Walleyes, as East Vermilion generally has higher numbers, but West Vermilion produces a larger average size. Understanding this split can help anglers tailor their approach depending on whether they want numbers, size, or a mix of both.

Walleye: Walleye fishing remains the backbone of the Vermilion experience. Survey data from 2025 showed one of the highest catch rates in over four decades. The 2026 season should be especially rewarding for anglers looking to harvest fish. Strong numbers of Walleyes in the 13-20-inch range mean plenty of legal fish under the protected slot. Fish in the 12-15-inch range are particularly abundant, providing good harvest opportunities.

At the same time, larger Walleyes are common enough to provide big fish opportunities. Fish over 20 inches are widely available, giving anglers a shot at memorable catches even while targeting smaller fish for harvest. The current regulation requires release of fish from 20 to 26 inches, with a four-fish limit and only one over 26 inches allowed. For anglers, that means a balanced fishery featuring good harvest opportunities without sacrificing the chance at bigger fish.

Muskellunge: Muskies provide a world-class sport fishery on Lake Vermilion with the potential for trophy fish. Muskies are second only to Walleyes in terms of popularity for Lake Vermilion anglers. Recent surveys show an average size just under 45 inches, with over 40% of fish exceeding that mark. Fish over 50 inches are present in sufficient numbers to provide trophy opportunities. For anglers, this creates a classic Muskie experience: fewer strikes, but every one of them matters. Vermilion has earned its reputation as a world-class destination because those rare encounters can turn into truly exceptional fish.

Smallmouth Bass: Smallmouth Bass are found throughout Lake Vermilion, and the population provides an important fishery. They are typically the third most sought after species by Lake Vermilion anglers behind Walleyes and Muskies. Results from the 2025 spring electrofishing survey suggest numbers remain high which continues the upward trend over the last three decades. Anglers can expect steady action with fish in the 10-17-inch range, along with the occasional larger bass. The lake's two basins offer slightly different experiences. West Vermilion tends to produce more fish overall, while East Vermilion gives anglers a better shot at larger individuals. For anglers looking for numbers, action, and aggressive strikes, Smallmouth Bass are a dependable option throughout the season.

Largemouth Bass: Largemouth Bass are not a primary draw on Vermilion, but they do offer a quiet alternative for anglers willing to seek them out. They are found mainly in West Vermilion in specific habitats. Numbers are low, but the population appears stable or increasing. Most anglers treat them as a catch-and-release bonus rather than a target species.

Northern Pike: Northern Pike are found in low abundance in Lake Vermilion, but anglers seeking them can find higher numbers in West Vermilion. Northern Pike are less abundant than in the past, but the fish that remain are generally larger. Regulations protecting mid-sized fish have shifted the population toward bigger individuals. Anglers can expect a lower catch rate, but with the possibility of occasional trophies. In 2025, sampled pike length averaged almost 27 inches with the largest fish measuring about 36 inches suggesting anglers and spearers can find fish with a solid average size.

Panfish and Perch: Yellow Perch numbers are currently below average, but size is good. Anglers willing to search can still find fish over 10 inches, which are well worth keeping.

Black Crappies are generally a minor component of the Lake Vermilion fishery that can provide good fishing opportunities at certain times. Black Crappies are not abundant, but they run large. Fish average around 10 inches, with some exceeding 14 inches. West Vermilion holds more fish overall, though both basins can produce quality catches.

Bluegills can provide catch and harvest opportunities for anglers fishing Lake Vermilion. Typically, very few anglers come to Lake Vermilion seeking Bluegills, but they tend to be one of the most caught and harvested species in terms of total numbers. Fish over 9 inches are available throughout the lake, with higher numbers in West Vermilion.
