Stocking history
| Year | Species | Size | Number | Pounds |
|---|---|---|---|---|
| 2025 | Walleye | fingerlings | 340 | 20.0 |
| 2025 | Walleye | yearlings | 137 | 91.0 |
| 2023 | Walleye | fingerlings | 3,050 | 70.0 |
| 2021 | Walleye | fingerlings | 1,035 | 90.0 |
| 2019 | Walleye | fingerlings | 1,216 | 64.0 |
| 2017 | Walleye | adults | 210 | 105.0 |
Field note · Minnesota stocks by year, not by truck day: walleye fry go in within weeks of ice-out, fingerlings and yearlings mostly in fall, and stream trout in spring and fall. A row here means the fish went in during that year; DNR adds the year's rows after the fact, so the current year can look empty until winter.

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
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…
