32-acre lake near Alger County. The lake tops out around 40 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
The outline encloses 38 acres, worked by 1 miles of shoreline. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 30% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. Alger County claims this one. Its nearest charted neighbour, Ready Lake, is 2 mi to the southwest.
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 25 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 (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (4 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (8 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 25 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 | Secondary point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (25 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Secondary point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (25 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 12 to 40 ft, wintering in 5 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 25 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 (4 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 12 to 40 ft | night & dawn | Break off the point (25 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Secondary point (9 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (25 ft) | Jigging spoon, Small stickbait (slow) |
Spring coho salmon on Mirror Lake hold shallow, usually 3 to 25 ft. By summer they slide out to 12 to 40 ft, and by winter most fish are in 12 to 40 ft. The chart's best answer is Deep basin — deep basin, 39 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a dodger + fly or a medium spoon above the thermocline.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (4 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 12 to 40 ft | dawn & dusk | Deep basin (39 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 8 to 40 ft | dawn & dusk | Secondary point (9 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 12 to 40 ft | midday | Deep basin (39 ft) | Small spoon, slow troll |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 8 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (25 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (39 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 8 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (8 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (8 ft) | Tip-ups, Large jigging spoon |
