100-acre lake near Itasca County. The lake tops out around 16 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
The drawn water covers 100 acres wrapped in 1.6 miles of bank. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 91% of this chart, as modeled. Figure 0.6 mi of water from one end to the other, 0.4 mi at the beam. It sits in Itasca County. If the bite dies, Clearwater is 1 mi to the southwest.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 5 to 16 ft; cold water stacks them in 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring 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.
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 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Round hold shallow, usually 2 to 8 ft. They move out to 5 to 16 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

Early season largemouth bass use the shallows, holding in 2 to 10 ft. Summer is a 5 to 16 ft game here, winter a 5 to 16 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
