20-acre lake near Menominee County. The lake tops out around 29 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Lake Ann maps at 22 acres behind 0.8 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 51% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.3 mi end to end and 0.2 mi across at its widest. It sits in Menominee County. If the bite dies, Lake Mary is 0 mi to the southwest.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 9 to 29 ft before dropping to 9 to 29 ft for winter. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 29 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 9 to 29 ft | dawn | Deep basin (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 29 ft | midday | Deep basin (29 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 29 ft | midday & dawn | Deep basin (29 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |

| Fall | 8 to 25 ft | midday & dawn | Break off the point (20 ft) | Jerkbait, Blade bait |

Spring largemouth bass on Lake Ann hold shallow, usually 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 9 to 29 ft. Put Break off the point first on the milk run — a drop-off near 20 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (20 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
