Rates come from standard DNR survey gear (gill nets, trap nets, electrofishing), judged against statewide benchmarks for the same gear, so the same number of fish per net can read differently for two species. Where the standard gear can't count a species reliably, only presence and size are listed. Typical is the middle fish of those measured. Open a row for the full length spread, survey by survey.

How to fish Six Lake through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. At 18.3 ft of clarity, fish them deeper and lighter than usual.
Early summer
Walleye are setting up on the outside weed edge, points and shallow structure.
Summer
Walleye are working the weed edge, points and any wind-blown structure. On a lake that drops to 140 ft, check the deep edge of that structure too.
Fall
Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows.

Northern pike

Spring
Pike are in the shallow bays and along new weed growth. At 18.3 ft of clarity, fish them deeper and lighter than usual.
Early summer
Pike are on the outside weed edge and points.
Summer
Pike are on the deep weed edge and points near the coolest water they can find. On a lake that drops to 140 ft, check the deep edge of that structure too.
Fall
Pike are on the last green weeds and the breaks beside them, feeding heavily as the water drops.

MN DNR · in their words

From the 2019 survey

Lake Six is a 188-acre oligotrophic (low fertility) lake located in north-central Otter Tail County approximately two miles north of Vergas, MN. The immediate watershed is composed of mixed hardwood woodlots. The maximum depth is 140 feet; however, 34% of the lake is 15 feet or less in depth. The secchi disk reading during the 2019 survey was 17.8 feet. Previous secchi disk readings ranged from 8.5 to 19.5 feet.

Lakeshore development is located primarily along the west and north shorelines. Homes and cabins compose the majority of the development. A DNR owned concrete public water access is located along the south shoreline. The shoal water substrates consist primarily of sand and gravel. Hardstem bulrush and common cattail are prevalent in various areas throughout the lake. These emergent aquatic plants provide valuable fish and wildlife habitat and are critical for maintaining good water quality. They protect shorelines and lake bottoms from wave erosion and can absorb and breakdown polluting chemicals. Emergent plants also provide spawning habitat for fish species such as Northern Pike, Largemouth Bass, and panfish. They also serve as important nursery areas for all species of fish. Because of their significant ecological value, emergent plants may not be removed from the lake without a DNR permit. To maintain the excellent water quality and angling that this lake has to offer, it is imperative to preserve the quality of the aquatic habitat.

Walleye, Northern Pike, and Largemouth Bass are the dominant gamefish species in the fish community of Lake Six.

Walleyes ranged in length from 15.7 to 23.7 inches with an average length and weight of 18.4 inches and 2.1 pounds. Walleyes attain an average length of 14.9 inches at four years of age.

Northern Pike ranged in length from 9.5 to 35.4 inches with an average length and weight of 18.5 inches and 1.6 pounds. Northern Pike attain an average length of 21.6 inches at five years of age.

Largemouth Bass ranged in length from 6.3 to 15.8 inches with an average length and weight of 11.1 inches and 0.8 pounds. Largemouth Bass attain an average length of 11.9 inches at five years of age.

Anglers can maintain or improve the quality of fishing on Lake Six by practicing selective harvest. Selective harvest encourages the release of medium to large fish while allowing the harvest of the more numerous, smaller fish for eating. Releasing medium to large fish ensures that the lake will have enough spawning aged fish and will also provide anglers with opportunities to catch larger fish in the future.

Lake Six is not listed as an infested water. Aquatic invasive species are threatening Minnesota waters. Aquatic invasive species can potentially harm water quality, water recreation, aquatic habitat, native species, and fish populations. Anglers can help prevent the introduction and spread of invasive species by following watercraft transportation laws.
