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.
Mill Lake is a 167-acre lake that is primarily managed for Northern Pike, Largemouth Bass, and Walleye and secondarily managed for Black Crappie and Bluegill. Walleye fingerlings are stocked biennially but age-2 fish were stocked in 2017 and 2025. The lake is located 9 miles southeast of Browerville and has relatively low residential development. The maximum depth is 18 feet and water clarity has been 10-11 feet during recent surveys. Mill lake has a variety of submerged, emergent, and floating-leaf vegetation along the shoreline. A standard survey was conducted during 2025 and included spring electrofishing and summer gill netting. Northern Pike had a catch rate of 4.8 fish/net (total = 29), the highest recorded since 1995 (5.5 fish/net). Catch rates during the last four surveys have varied between 1.5-3.7 fish/net. During 2025, fish ranged in size from 17.8-38.9 inches (average = 15.7 inches) with 35% over 24 inches. This was a decline in size structure from 2019 (average = 26.9 inches; 93% over 24 inches) and 2013 (average = 27.8 inches; 82% over 24 inches). Mill has historically provided a notable Northern Pike fishery with fish over 30 inches regularly sampled. Due to the recent increase in pike abundance, anglers are encouraged to harvest fish that are less than 22 inches. The catch rate of Largemouth Bass while electrofishing was 71.7 fish/hour (total = 77). Numbers of bass have been declining over the years after hitting an all-time high during 2013 (157.7 fish/hour). During 2025, Largemouth Bass measured 3.3-14.5 inches (average = 10.0 inches). The population is predominantly made up of fish that are 6.5-8.9 inches and 11.0-14.5 inches, with a complete absence of fish over 15 inches. Mill Lake has been reported to winterkill on occasion, which may explain the decline in abundance and size structure. Walleye had a catch rate of 5.7 fish/net (total = 34), which was a record high. The previous survey during 2019 had a catch rate of 2.8 fish/net and from 1995-2013 the catch was less than 0.5 fish/net. Walleye ranged in size from 10.0-24.1 inches (average = 15.7 inches) during 2025. Length frequency data indicated that multiple cohorts of stocked fish were present providing anglers with a variety of sizes. Fish were reaching 12.9 inches by age-2, 16.1 inches by age-4, 16.8 inches by age-6, 18.9 inches by age-8, and 23.5 inches by age-10. The recent increase in numbers should improve opportunities for anglers to harvest fish. Gill netting resulted in the capture of 28 Bluegill and 18 Black Crappie. Bluegill were 3.8-9.8 inches (average = 6.5…
