25-acre lake near Houghton County. The lake tops out around 36 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 20 acres wrapped in 1 miles of bank. With a 1.7 development index there's bank structure worth casting at, in moderation. Roughly 84% 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. Houghton County claims this one. Its nearest charted neighbour, Toivola Lake (West), is 3 mi to the west.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Deep basin — deep basin, 29 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| 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 | Deep basin (29 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 (2 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring rainbow trout on Thirteenmile Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 7 to 36 ft. Put Deep basin first on the milk run — a deep basin near 29 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (4 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Deep basin (29 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Deep basin (29 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 36 ft | dawn | Deep basin (29 ft) | Jigging spoon, Tube jig (white) |
In spring, brown trout run shallow here, mostly 3 to 25 ft. Summer pushes them deeper, 11 to 36 ft, and winter fish settle into 5 to 35 ft. Deep basin is the standout, a deep basin at roughly 29 ft, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
| 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 36 ft | night & dawn | Deep basin (29 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (4 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Deep basin (29 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: cisco (lake herring) sit in 9 to 36 ft that time of year. They don't go far with the seasons — 11 to 36 ft covers summer, 11 to 36 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 29 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 36 ft | dawn & dusk | Deep basin (29 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 11 to 36 ft | dawn | Deep basin (29 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 11 to 36 ft | dawn | Deep basin (29 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts sauger in skinny water — 4 to 18 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 11 to 36 ft. Deep basin is the standout, a deep basin at roughly 29 ft, rated prime for winter sauger. Plan around early morning and the evening in the warm months. A bottom bouncer + crawler or a 3-way rig with stickbait covers the summer program.
| 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 | Deep basin (29 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Fall | 12 to 35 ft | dusk & dawn | open water | Jig + big minnow, Blade bait |
| Winter | 11 to 36 ft | dusk | Deep basin (29 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Top water on the chart: Deep basin, a deep basin in the 29 ft range, prime in fall. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
