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.
Imogene Lake is a 185-acre lake located four miles east of the City of Fairmont in Martin County. The lake has a maximum depth of 6.0 ft. and typically has turbid water (Secchi depth 0.6 ft.) and dense algae blooms. Imogene Lake is managed primarily for Northern Pike and Yellow Perch and secondarily for Walleye. A standard survey was conducted the week of July 19, 2021 to monitor fish populations using gill nets and trap nets. Since 2003, Northern Pike catch rates have varied from 0.0 to 7.5 per gill net and have averaged 2.7 per gill net. In 2021, one 27.1 inch Northern Pike was sampled in trap nets and zero were sampled in gill nets. Prior to 2021, Northern Pike have not been stocked since 2014, indicating that they are not able to sustain their population through natural reproduction. While Imogene Lake does not have your typical Northern Pike habitat, it is susceptible to winterkill which is the main driver towards Northern Pike management. We expect to stock Northern Pike in order maintain a presence in Imogene Lake as a large predator that is more tolerant of low dissolved oxygen during winter. During the fall of 2021, 284 Northern Pike fingerlings were stocked to supplement the population. The Yellow Perch catch rate decreased from 17.0 per gill net in 2015 to 1.5 per gill net in 2021 and was below the expected range of catch rates for similar lakes (2.7 to 25.0 per gill net). Lengths of Yellow Perch in gill nets and trap nets ranged from 4.6 to 10.6 inches and averaged 7.2 inches. The yellow Perch population in Imogene Lake should continue to be monitored for adverse effects from the newly introduced Yellow Bass population. The low abundance of Yellow Perch may be a byproduct of a record catch of Walleye. Prior to 2021, Walleye catch rates varied from 0.0 per gill net in 2003 to 1.5 per gill net in 2009. In 2021, Walleye were captured at a rate of 16.0 per gill net, which is near the upper end of expected catch rates for similar lakes (18.1 per gill net). Four year classes of Walleye were sampled including ages 1, 2, 5, and 7. Age-1 Walleye were likely the result of natural reproduction because fry or fingerlings were not stocked in 2020. These naturally reproduced Walleye from 2020 compose a small percentage of the catch, it is important to recognize the habitat in some year on Imogene Lake is sufficient. The other year classes correspond to fingerling and yearling stockings. Mean length at age-2 was 14.4 inches, which indicates fast growth. Walleye lengths ranged from 10.9 to 24.7 inches and averaged 17.2 inches. Fingerling, yearling, and…
