2 fish purchased by the DNR for stocking.
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 Johanna is a 213-acre, eutrophic lake located in Arden Hills, 7.5 miles northwest of St. Paul. The contributing watershed is characterized by residential, commercial, industrial and major roadways. Overall, water quality in Lake Johanna is very good. The most recent data indicates that it is one of the best lakes in the Rice Creek Watershed District in terms of phosphorus concentrations. Ramsey County has maintained a very popular 217-acre park which is bounded by Lake Johanna and County Road E to the south. The park includes ¼ mile of shoreline on the north side of Lake Johanna. Surface water use of this lake is very high. The 1994 creel survey estimated fishing use at 62-angler hours/acre. Ramsey County has established surface water use restrictions that limit the hours, watercraft speed, and nature of surface water use allowed. Lake Johanna is primarily for Walleyes and Tiger Muskellunge. Walleyes were captured at a rate of 2.50 fish/gill net. Walleyes captured during this assessment averaged 19.1 inches in total length, and 93% of Walleye captured during the survey were 15 inches or larger. A total of three Tiger Muskellunge were captured during this assessment. Tiger Muskellunge averaged 29 inches in total length. The largest Tiger Muskellunge sampled was 43 inches. Northern Pike were captured at the second highest rate of abundance ever at 10.2/gill net. Northern Pike in gill nets averaged 22.4 inches, and 16% of pike captured were 26 inches or larger. Lake Johanna is in the North Central Northern Pike Management Zone which has a protected slot of 22-26 inches and a harvest limit of two fish not longer than 26 inches and a ten fish limit under 22inches. Yellow Perch were sampled at the lowest abundance ever observed on Lake Johanna of one per gill net. Yellow Perch lengths ranged from 5.1 to 7.5 inches. For the last 20 years Bluegill trap net abundance has decreased every survey from 223.2 in 2001, to 18.1 fish/trap net in 2021. Average total length of Bluegills in trap nets was 4.4 inches. Black Crappies relative abundance has been consistent in gill nets and increased in trap nets from the previous surveys in 2014 and 2017. Average length of Black Crappie in gill nets was 5.4 inches and 4.8 inches in trap nets. Although gill nets and trap nets are not the best way to assess Largemouth Bass, seven were sampled in trap and gill nets. Other species captured during this survey in low numbers were Bowfin, Golden Shiners, Hybrid Sunfish, Pumpkinseed, and Yellow Bullheads.
