23-acre lake near Alger County. The lake tops out around 19 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.
On the chart, Niemi Lake draws 25 acres inside 0.9 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 93% of this chart. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. The water lies in Alger County. Closest neighbour on DepthScout: Weber Lake, 0 mi southeast of here.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 6 to 19 ft, then a winter hold in 6 to 19 ft. Put Deep basin first on the milk run — a deep basin near 18 ft that grades prime for fall. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| 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 | 6 to 19 ft | dawn | Deep basin (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 19 ft | midday | Deep basin (18 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 19 ft | midday & dawn | Deep basin (18 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 6 to 19 ft, and winter fish settle into 5 to 15 ft. Main-lake point is the standout, a point at roughly 6 ft, rated prime for fall northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| 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 | 6 to 19 ft | dawn & dusk | Main-lake point (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Main-lake point (6 ft) | Tip-ups, Large jigging spoon |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 6 to 19 ft, and winter fish settle into 6 to 19 ft. Main-lake point is the standout, a point at roughly 6 ft, rated prime for fall smallmouth bass. Time it for early morning and the evening. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (6 ft) | Ned rig, Tube jig |
| Summer | 6 to 19 ft | dawn & dusk | Main-lake point (6 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 19 ft | midday & dawn | Main-lake point (6 ft) | Jerkbait, Blade bait |
| Winter | 6 to 19 ft | midday | Deep basin (18 ft) | Blade bait, Hair jig |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. Expect a summer slide to 5 to 19 ft, then a winter hold in 6 to 19 ft. Start at Main-lake point. It's a point holding about 6 ft of water and rates prime come summer. Prime time lands in the evening. A ned rig (small) or a marabou jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (6 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 19 ft | dusk | Main-lake point (6 ft) | Ned rig (small), Marabou jig |
| Fall | 6 to 19 ft | midday | Main-lake point (6 ft) | Small tube jig, Inline spinner |
| Winter | 6 to 19 ft | midday | Deep basin (18 ft) | Tungsten jig + plastic, Small spoon + spike |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 6 to 18 ft. Start at Deep basin. It's a deep basin holding about 18 ft of water and rates prime come winter. Prime time lands in the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | open water | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (18 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 6 to 19 ft. The spot to know is Deep basin, a deep basin in about 18 ft of water that rates prime for brown bullhead in winter. Warm-month bites cluster around 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 | open water | |
