5-acre lake in Marinette County, Wisconsin. The lake tops out around 35 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
Perch Lake maps at 5 acres behind 0.3 miles of shoreline. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. 24% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Marinette County claims this one. Bullhead Lake sits 0 mi southwest — the closest neighbouring chart.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 7 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 16 ft that scores prime in winter. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 35 ft | dawn | Break off the point (16 ft) | Jigging spoon, Tube jig (white) |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Put Main-lake point first on the milk run — a point near 9 ft that grades prime for fall. In summer the feeding windows fall in 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 | 2 to 10 ft | dawn & dusk | Main-lake point (9 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (16 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (9 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (16 ft) | Blade bait, Jigging spoon |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 30 ft.
