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.
Greenleaf Lake is a 302-acre lake located approximately 3.5 miles southwest of the town of Montgomery in Le Sueur County. The DNR-owned public access is located on the northeast shore off County Road 140. Greenleaf Lake has a maximum depth of 19 feet, with approximately 87% of the lake less than 15 feet deep. Greenleaf Lake is primarily managed for Bluegill and Walleye and secondarily for Black Crappie and Largemouth Bass. The management plan calls for stocking Walleye fry at a rate of 1,000 fish/littoral acre in odd years. Recent stocking events include fry in 2019, 2021, and 2023. Periodic winterkills were common before the installation of an aerator in 1983. Since that time, winterkills had not been a factor until 2019 when a near complete winterkill took place. High levels of phosphorus have contributed to poor water quality and extensive algae blooms that result in poor water quality. The lack of aquatic vegetation remains a challenge for managing stable game fish populations. Greenleaf Lake was surveyed the week of 8 July 2024 as part of a regular monitoring program conducted by the Minnesota DNR. This survey was intended to assess the fish community by deploying 6 gill nets, 9 trap nets, and 44 minutes of boat electrofishing as well as recording water quality parameters. A total of 480 Bluegills were sampled with trap nets for a catch rate of 53.3/net. Since 1984, catch rates have varied from 3.3/net to 142.0/net with an average of 34.2/net. Bluegills ranged from 3.3 to 8.3 inches with an average of 7.1 inches. Bluegills were aged using scales and otoliths and ranged from 1 to 5 years old with 5 year-classes present. Three and four year old Bluegills accounted for approximately 80% of the sample. A total of 5 Walleyes were sampled with gill nets for a catch rate of 0.8/net. Walleyes ranged from 12.0 to 16.5 inches. Walleye were abundant in trap nets during the 2021 survey and it is not clear what caused numbers to drastically decline between surveys. Yellow Perch were the most common non-bullhead species sampled with gill nets in 2024. A total of 440 Yellow Perch ranging from 5.6 to 9.1 inches were sampled for a catch rate of 73.3/net. Broodstock Yellow Perch were stocked in 2019, and natural reproduction has been successful. Black Bullheads dominated the gill net catches in 2024. A total of 705 were sampled with gill nets for a catch rate of 117.5 per net which was a decrease from 202.4/net in 2021. Since 1984, catch rates have varied from 8.0/net in 1994 to 274.0/net in 1985 with an average of 111.2/net. Bullheads ranged from 4.7 to 15.9…
