Rating depth structure for largemouth bass.

18-acre reservoir in Portage County, Wisconsin. The lake tops out around 7 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 18 acres wrapped in 1.3 miles of bank. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.5 mi of water from one end to the other, 0.2 mi at the beam. It sits in Portage County. If the bite dies, Lions Lake is 2 mi to the northeast.
Spring puts yellow perch in skinny water — 2 to 7 ft is the zone. Summer fish stay in 2 to 7 ft, and winter fish hold in 2 to 7 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 7 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season largemouth bass use the shallows, holding in 1 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 2 to 7 ft. 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 7 ft | midday & dawn | Main-lake point (7 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 7 ft | midday | Deep basin (6 ft) | Blade bait, Jigging spoon |
Spring crappie on Rosholt Millpond hold shallow, usually 2 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 2 to 7 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 6 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a jig trolled/spider-rigged or a small crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 2 to 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 7 ft | dawn | Shallow bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 7 ft | midday | Deep basin (6 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring bluegill on Rosholt Millpond hold shallow, usually 1 to 6 ft. By summer they slide out to 2 to 7 ft, and by winter most fish are in 2 to 7 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
