27-acre lake near Houghton County. The lake tops out around 38 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
There are 1 miles of drawn shoreline to work. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. 46% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 0.3 mi long by 0.3 mi wide at the broadest reach. The water lies in Houghton County. For a second option, Thirteenmile Lake lies 3 mi south.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Break off the point, a drop-off in the 19 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| 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 (19 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 | Break off the point (19 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 38 ft for winter. The spot to know is Break off the point, a drop-off in about 19 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Secondary point (7 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (19 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (19 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 38 ft | dawn | Break off the point (19 ft) | Jigging spoon, Tube jig (white) |
Early season brown trout use the shallows, holding in 3 to 25 ft. Summer is an 11 to 38 ft game here, winter a 5 to 35 ft one. The chart's best answer is Break off the point — drop-off, 19 ft, prime for summer. Best bite is after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
| 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 | 11 to 38 ft | night & dawn | Break off the point (19 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Secondary point (7 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Break off the point (19 ft) | Jigging spoon, Small stickbait (slow) |
When the water first warms, cisco (lake herring) slide up into 10 to 38 ft. There's no big seasonal slide here — summer means 11 to 38 ft, winter 11 to 38 ft. If you only fish one area, make it Deep basin: a deep basin around 36 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 38 ft | dawn & dusk | Deep basin (36 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 11 to 38 ft | dawn | Deep basin (36 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (19 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 11 to 38 ft | dawn | Deep basin (36 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
When the water first warms, sauger slide up into 4 to 18 ft. Summer is a 10 to 30 ft game here, winter an 11 to 38 ft one. Start at Deep basin. It's a deep basin holding about 36 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a bottom bouncer + crawler or a 3-way rig with stickbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Main-lake point (4 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Fall | 12 to 35 ft | dusk & dawn | Break off the point (19 ft) | Jig + big minnow, Blade bait |
| Winter | 11 to 38 ft | dusk | Deep basin (36 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
Spring yellow perch on Lake Perrault hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Deep basin — deep basin, 36 ft, prime for fall. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| 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 | 10 to 30 ft | dawn | Break off the point (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (36 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (36 ft) | Tungsten jig + spikes, Rattle spoon (small) |
