64-acre lake near Oakland County. The lake tops out around 51 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 50 acres of water rimmed by 1.5 miles of bank. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 26% of the water is 15 ft or less, the band where the food chain lives. Figure 0.6 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Oakland County. For a second option, Alderman Lake lies 1 mi southeast.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Secondary point, a point in the 10 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (37 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (11 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season brown trout use the shallows, holding in 3 to 25 ft. Summer is a 15 to 51 ft game here, winter a 5 to 35 ft one. The chart's best answer is Break off the point — drop-off, 37 ft, prime for summer. Best bite is after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (18 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 15 to 51 ft | night & dawn | Break off the point (37 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (18 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (37 ft) | Jigging spoon, Small stickbait (slow) |
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. By summer they slide out to 15 to 51 ft, and by winter most fish are in 15 to 51 ft. If you only fish one area, make it Deep basin: a deep basin around 49 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (49 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 15 to 51 ft | dawn | Deep basin (49 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 15 to 51 ft | dawn | Deep basin (49 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring yellow perch on Upper Pettibone Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Shallow bay flat — weed flat, 11 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (11 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (11 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (37 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (37 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Winter northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 11 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.

Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 20 to 45 ft. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 18 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.
