125-acre lake near Charlevoix County. The lake tops out around 52 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 117 acres of water rimmed by 2.3 miles of bank. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 53% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 1 mi with a 0.3-mi widest point. The water lies in Charlevoix County. The nearest mapped water is Skinner Lake, 2 mi to the west.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Break off the point, a drop-off in about 16 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (16 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (16 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 16 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Break off the point (16 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 | Break off the point (16 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (16 ft) | Jigging spoon, Tube jig (white) |
Spring brown trout on Lake Marion hold shallow, usually 3 to 25 ft. They move out to 16 to 52 ft in summer and finish the year down in 5 to 35 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for summer. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 16 to 52 ft | night & dawn | Break off the point (16 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Break off the point (16 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (16 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: chinook salmon sit in 5 to 40 ft that time of year. Summer pushes them deeper, 16 to 52 ft, and winter fish settle into 16 to 52 ft. The spot to know is Deep basin, a deep basin in about 51 ft of water that rates prime for chinook salmon in summer. Warm-month bites cluster around early morning and the evening. Throw a flasher + fly (green/white) or a magnum spoon on downrigger until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 40 ft | dawn & dusk | Break off the point (16 ft) | Trolled spoon (orange/gold), Stickbait off planer boards |
| Summer | 16 to 52 ft | dawn & dusk | Deep basin (51 ft) | Flasher + fly (green/white), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dawn & dusk | Break off the point (16 ft) | J-plug (glow), Flasher + fly |
| Winter | 16 to 52 ft | midday | Deep basin (51 ft) | Small spoon on a slow troll, Stickbait deep |
Spring puts coho salmon in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 16 to 52 ft, wintering in 16 to 52 ft. Summer coho salmon concentrate at Deep basin, a prime-rated deep basin around 51 ft. Warm-month bites cluster around early morning and the evening. A dodger + fly or a medium spoon above the thermocline covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Break off the point (16 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 16 to 52 ft | dawn & dusk | Deep basin (51 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 8 to 40 ft | dawn & dusk | Break off the point (16 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 16 to 52 ft | midday | Deep basin (51 ft) | Small spoon, slow troll |
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. Expect a summer slide to 16 to 52 ft, then a winter hold in 16 to 52 ft. Start at Deep basin. It's a deep basin holding about 51 ft of water and rates prime come summer. Prime time lands in early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (51 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 16 to 52 ft | dawn | Deep basin (51 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (16 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 16 to 52 ft | dawn | Deep basin (51 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
