95-acre lake near Oscoda County. The lake tops out around 50 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.
Traced from the shoreline, Loon Lake runs 94 acres with 2 miles of edge. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. 47% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.6 mi with a 0.5-mi widest point. You'll find it in Oscoda County. For a second option, Island Lake lies 1 mi south.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 14 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| 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 (14 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 (14 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. Break off the point is the standout, a drop-off at roughly 14 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| 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 (14 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 (14 ft) | Jigging spoon, Tube jig (white) |
When the water first warms, brown trout slide up into 3 to 25 ft. By summer they slide out to 15 to 50 ft, and by winter most fish are in 5 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 14 ft that scores prime in summer. In summer the feeding windows fall in after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.
| 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 | 15 to 50 ft | night & dawn | Break off the point (14 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 (14 ft) | Jigging spoon, Small stickbait (slow) |
Spring puts chinook salmon in skinny water — 5 to 40 ft is the zone. Warm water sends them out to 15 to 50 ft; cold water stacks them in 15 to 50 ft. Deep basin is the standout, a deep basin at roughly 48 ft, rated prime for summer chinook salmon. Plan around early morning and the evening in the warm months. A flasher + fly (green/white) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 40 ft | dawn & dusk | Break off the point (14 ft) | Trolled spoon (orange/gold), Stickbait off planer boards |
| Summer | 15 to 50 ft | dawn & dusk | Deep basin (48 ft) | Flasher + fly (green/white), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dawn & dusk | Break off the point (14 ft) | J-plug (glow), Flasher + fly |
| Winter | 15 to 50 ft | midday | Deep basin (48 ft) | Small spoon on a slow troll, Stickbait deep |
Spring cisco (lake herring) on Loon Lake hold shallow, usually 10 to 40 ft. They move out to 15 to 50 ft in summer and finish the year down in 15 to 50 ft. Put Deep basin first on the milk run — a deep basin near 48 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (48 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 15 to 50 ft | dawn | Deep basin (48 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |

| Winter | 15 to 50 ft | dawn | Deep basin (48 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 14 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| 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 |
