108-acre lake near St. Louis County. The lake tops out around 10 ft. The depth chart comes from Minnesota Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Heikkila maps at 108 acres behind 1.9 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.7 mi with a 0.4-mi widest point. St. Louis County claims this one. If the bite dies, Blackwood is 2 mi to the northwest.
Start shallow in spring: yellow perch sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
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 | 3 to 10 ft chart-limited; documented 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft chart-limited; documented 10 to 30 ft | dawn | open water | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft chart-limited; documented 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft chart-limited; documented 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 10 ft, then a winter hold in 3 to 10 ft. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
