48-acre lake near Presque Isle County. The lake tops out around 8 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 57 acres of water rimmed by 1.2 miles of bank. Nearly circular (index 1.1), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.4 mi with a 0.3-mi widest point. The water lies in Presque Isle County. The nearest mapped water is Shoepac Lake, 1 mi to the south.
Early season yellow perch use the shallows, holding in 2 to 8 ft. Even in summer they hold at 2 to 8 ft; winter keeps them in 2 to 8 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 8 ft | dawn | Deep basin (8 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 8 ft | midday | Deep basin (8 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 8 ft | midday & dawn | Deep basin (8 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer keeps them at 2 to 8 ft, and they winter in 2 to 8 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 8 ft | dawn & dusk | Shallow bay flat (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 8 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
In spring, smallmouth bass run shallow here, mostly 2 to 8 ft. Summer keeps them at 2 to 8 ft, and they winter in 2 to 8 ft. Main-lake point is the standout, a point at roughly 2 ft, rated prime for fall smallmouth bass. Time it for early morning and the evening. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 2 to 8 ft | dawn & dusk | Break off the point (7 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 8 ft | midday & dawn | Main-lake point (2 ft) | Jerkbait, Blade bait |
| Winter | 2 to 8 ft | midday | Break off the point (7 ft) | Blade bait, Hair jig |
Spring puts largemouth bass in skinny water — 2 to 8 ft is the zone. Summer fish stay in 2 to 8 ft, and winter fish hold in 2 to 8 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 8 ft | dawn & dusk | Shallow bay flat (2 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 8 ft | midday & dawn | Main-lake point (2 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 8 ft | midday | Break off the point (7 ft) | Blade bait, Jigging spoon |
Come spring, look for rock bass tight to the bank in 2 to 8 ft. Through summer count on 2 to 8 ft; the winter hold is 2 to 8 ft. Start at Main-lake point. It's a point holding about 2 ft of water and rates prime come summer. Prime time lands in the evening. A ned rig (small) or a marabou jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Main-lake point (2 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 2 to 8 ft | dusk | Main-lake point (2 ft) | Ned rig (small), Marabou jig |
| Fall | 2 to 8 ft | midday | Break off the point (7 ft) | Small tube jig, Inline spinner |
| Winter | 2 to 8 ft | midday | Deep basin (8 ft) | Tungsten jig + plastic, Small spoon + spike |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Summer pushes them deeper, 2 to 8 ft, and winter fish settle into 2 to 8 ft. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for bluegill in spring. Warm-month bites cluster around early morning and the evening. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 2 to 8 ft | dawn & dusk | Shallow bay flat (2 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 8 ft | midday | Shallow bay flat (2 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 8 ft | midday | Deep basin (8 ft) | Tungsten ice jig + plastic, Tiny spoon |
