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 Iron Chief Complex 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 262.1 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.

Crappie

Spring
Crappie are up in the back bays and against wood in a few feet of water, spawning shallower than most people fish for them.
Early summer
Crappie are pulling off the bays to the first deep weed edge and brush, still reachable shallow at dusk.
Summer
Crappie are over the basin of a stratified lake, well off any structure, which is why summer netting barely catches them inshore. On a lake that drops to 262.1 ft, check the deep edge of that structure too.
Fall
Crappie are schooled along the deep weedline and the basin edge, pushing shallow to feed at dusk while the water still turns over slowly.

MN DNR · in their words

From the 2008 survey

Iron Chief Complex is a series of three abandoned mine pits (now connected) near the town of Buhl. Like most pit lakes, the water is relatively infertile and clear. Rainy and windy weather occasionally loosens sediment from the pit walls causing the water to cloud up temporarily. There is a city-owned public access on the south side of the lake. DNR Fisheries has done no stocking or management of the lake, and the 2008 assessment was the first ever conducted on the pit.

Very few fish were captured in the test nets. Green sunfish was the most numerous species in the standard assessment gears, at 1.2/gill net and 1.2/trap net. These fish were rather small, ranging from 3.7 to 5.6 inches in length. Four rainbow smelt were also captured in the gill nets for a catch rate of 0.7/net.

Read the full DNR narrative

Two small-mesh gill nets specifically designed to sample small fish such as rainbow smelt were also used in this assessment. A total of 32 smelt were captured for a catch rate of 16/net. These fish ranged from 4.6 to 6.3 inches in length.

One northern pike (28.4 inches) was captured in a trap net. This was the only large predator fish sampled. Other fish sampled in low numbers were black bullhead, black crappie, blacknose shiner, bluegill and white sucker. Good water quality characteristics and the presence of a modest population of rainbow smelt appear to make Iron Chief Complex suitable for a cold-water species such as lake trout.
