15-acre lake near Aitkin County. The lake tops out around 14 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Previs draws 15 acres inside 0.7 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 0.3 mi long. You'll find it in Aitkin County. For a second option, Hill (North Basin) lies 1 mi southwest.
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 12 ft; cold water stacks them in 4 to 14 ft. Deep basin is the standout, a deep basin at roughly 12 ft, rated prime for winter brown bullhead. Plan around after dark and the evening in the warm months.
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 | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 4 to 14 ft chart-limited; documented 5 to 15 ft | dusk | Deep basin (12 ft) | |
| Winter | 4 to 14 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (12 ft) |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 12 ft.
