38-acre lake near Itasca County. The lake tops out around 52 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 38 acres wrapped in 1.5 miles of bank. With a 1.7 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 40% of this chart, as modeled. Figure 0.4 mi of water from one end to the other, 0.3 mi at the beam. It sits in Itasca County. If the bite dies, Cottonwood is 2 mi to the south.
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (13 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (13 ft) | Squarebill crankbait (shad), Spinnerbait |
