Stocking history

Year	Species	Size	Number	Pounds
2025	Walleye¹	adults	1,000	250.0
2025	Walleye¹	fry	100,000	0.8

¹ fish purchased and stocked by private citizens and sporting groups.

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.

Northern pike abundance decreased slightly from 2.7 per gill net lift in the 1986 survey to 2.0 per net, which is below the normal range for this lake class. Average individual weight of northern pike increased from1.5 pounds in 1986 to 2.4 pounds. Northern pike age structure indicates consistent reproduction and recruitment; however, no pike from the 1988 stocking were sampled. Black bullhead abundance increased dramatically from 37.3 per trap net lift in 1986 to 113.3 per net, which six times greater than the upper limit of the normal range. Bluegill abundance increased slightly from 7.3 per trap net lift in 1986 to 8.6 per net, remaining within the normal range. Bluegill recruitment appears to be consistent and a strong 1987 year class (age-IV+) composed 50% of the sample. Mean lengths-at-age indicate average growth compared to statewide means. Forty-eight percent of the bluegills sampled were 7.0 inches or greater in length. Yellow perch abundance was 2.0 per gill net lift, which is below the normal range. Walleye abundance declined slightly from 1.3 per gill net lift in 1986 to 1.0 per net, but remains within the normal range. The average weight of individual walleye increased from 1.0 pounds in 1986 to 1.5 pounds. Walleye recruitment appears to be inconsistent. Walleyes sampled from the 1985 and 1990 year classes were the result of stocking and natural reproduction, respectively.
