567-acre lake near St Louis County. The lake tops out around 25 ft. The depth chart comes from Minnesota Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Minnesota DNR survey of 1969, a decades-old survey (the DNR's original lake-survey map). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 567 acres, worked by 9.9 miles of shoreline. With a shoreline index of 3, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 92% of this chart. Figure 2.3 mi of water from one end to the other, 1.3 mi at the beam. It sits in St. Louis County. Its nearest charted neighbour, Net, is 2 mi to the north.
Spring puts lake whitefish in skinny water — 8 to 25 ft is the zone. Summer fish stay in 8 to 25 ft, and winter fish hold in 8 to 25 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 25 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 25 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (7 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 8 to 25 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (25 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 7 to 25 ft chart-limited; documented 8 to 30 ft | dusk | Break off the point (7 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 8 to 25 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (25 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 8 to 25 ft; cold water stacks them in 8 to 25 ft. Top water on the chart: Deep basin, a deep basin in the 25 ft range, prime in winter. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 25 ft; cold water stacks them in 8 to 25 ft. Deep basin is the standout, a deep basin at roughly 25 ft, rated prime for fall yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

Spring northern pike on Little Johnson hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Break off the point first on the milk run — a drop-off near 7 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

Spring smallmouth bass on Little Johnson hold shallow, usually 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 8 to 25 ft.
