49-acre lake near Alger County. The lake tops out around 15 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Loon Lake's chart carries 1.2 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Call it 0.5 mi long. The water lies in Alger County. The nearest mapped water is Triangle Lake, 2 mi to the southeast.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 5 to 15 ft, then a winter hold in 5 to 15 ft. Start at Deep basin. It's a deep basin holding about 14 ft of water and rates prime come fall. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. The spot to know is Deep basin, a deep basin in about 14 ft of water that rates good for northern pike in fall. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Summer | 5 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 5 to 15 ft | midday & dawn | Deep basin (14 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Main-lake point (3 ft) | Tip-ups, Large jigging spoon |
Early season rock bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 5 to 15 ft. Put Deep basin first on the milk run — a deep basin near 14 ft that grades prime for winter. In summer the feeding windows fall in the evening. Tie on a ned rig (small) or a marabou jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (3 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 4 to 15 ft | dusk | Main-lake point (3 ft) | Ned rig (small), Marabou jig |
| Fall | 5 to 15 ft | midday | Main-lake point (3 ft) | Small tube jig, Inline spinner |
| Winter | 5 to 15 ft | midday | Deep basin (14 ft) | Tungsten jig + plastic, Small spoon + spike |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 5 to 15 ft. Deep basin is the standout, a deep basin at roughly 14 ft, rated prime for winter brown bullhead. Time it for after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | open water | |
| Summer | 3 to 12 ft | night & dusk | Deep basin (14 ft) | |
| Fall | 5 to 15 ft | dusk | Deep basin (14 ft) | |
| Winter | 5 to 15 ft | midday | Deep basin (14 ft) |
