110-acre lake near Cass County. The lake tops out around 30 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What follows comes from the same scoring engine that paints the spots above.
On the chart, Little Twin draws 110 acres inside 2.1 miles of shoreline. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 64% of this chart, as modeled. End to end it runs roughly 0.8 mi, about 0.3 mi across. The water lies in Cass County. Closest neighbour on DepthScout: Thirteen, 1 mi southeast of here.
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 9 to 30 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through 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 | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |

The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft.

Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
