50-acre lake near Alcona County. The lake tops out around 55 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
There are 1.2 miles of drawn shoreline to work. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 31% of this chart. Call it 0.4 mi long by 0.4 mi wide at the broadest reach. Alcona County claims this one. Its nearest charted neighbour, Brownlee Lake, is 1 mi to the west.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 17 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (17 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (17 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, rainbow trout slide up into 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. Start at Break off the point. It's a drop-off holding about 17 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| 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 (17 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 | 8 to 40 ft | dawn | Break off the point (17 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: brown trout in 3 to 25 ft. As the season builds they drop to 17 to 55 ft, wintering in 5 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 17 ft range, prime in summer. Time it for after dark and early morning. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (9 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 17 to 55 ft | night & dawn | Break off the point (17 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (9 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (17 ft) | Jigging spoon, Small stickbait (slow) |
Early season chinook salmon use the shallows, holding in 5 to 40 ft. Summer is a 17 to 55 ft game here, winter a 17 to 55 ft one. The chart's best answer is Deep basin — deep basin, 54 ft, prime for summer. Best bite is early morning and the evening. Tie on a flasher + fly (green/white) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 40 ft | dawn & dusk | Break off the point (17 ft) | Trolled spoon (orange/gold), Stickbait off planer boards |
| Summer | 17 to 55 ft | dawn & dusk | Deep basin (54 ft) | Flasher + fly (green/white), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dawn & dusk | Break off the point (17 ft) | J-plug (glow), Flasher + fly |
| Winter | 17 to 55 ft | midday | Deep basin (54 ft) | Small spoon on a slow troll, Stickbait deep |
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 17 to 55 ft before dropping to 17 to 55 ft for winter. Summer cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 54 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (17 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 17 to 55 ft | dawn | Deep basin (54 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (17 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 17 to 55 ft | dawn | Deep basin (54 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 17 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (9 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (17 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (17 ft) | Jigging rap, Jig + big minnow |
