Present and managed by the DNR.

Rates come from standard DNR survey gear (gill nets, trap nets, electrofishing), judged against statewide benchmarks for the same gear, so the same number of fish per net can read differently for two species. Where the standard gear can't count a species reliably, only presence and size are listed. Typical is the middle fish of those measured. Open a row for the full length spread, survey by survey.

How to fish Johanna Lake through the year

Northern pike

Spring
Pike are in the shallow bays and along new weed growth.
Early summer
Pike are on the outside weed edge and points.
Summer
Pike are on the deep weed edge and points near the coolest water they can find. On a lake that drops to 43 ft, check the deep edge of that structure too.
Fall
Pike are on the last green weeds and the breaks beside them, feeding heavily as the water drops.

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds.
Early summer
Walleye are setting up on the outside weed edge, points and shallow structure.
Summer
Walleye are working the weed edge, points and any wind-blown structure. On a lake that drops to 43 ft, check the deep edge of that structure too.
Fall
Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows.

MN DNR · in their words

From the 2021 survey

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.
