333-acre lake near Boundary. 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. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 332 acres of water rimmed by 3.6 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 43% of this chart. Tip to tip the water measures near 1.4 mi with a 0.6-mi widest point. The water lies in Division No. 9. For a second option, Strubel Lake lies 10 mi northeast.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 23 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| 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 (23 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 | Back-bay flat (3 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for brown trout tight to the bank in 3 to 25 ft. They move out to 12 to 40 ft in summer and finish the year down in 5 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 23 ft that scores prime in summer. Best bite is after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
| 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 (23 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 (23 ft) | Jigging spoon, Small stickbait (slow) |
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Summer fish stay in 12 to 40 ft, and winter fish hold in 10 to 40 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 40 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Secondary point (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 12 to 40 ft | dawn | Deep basin (40 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 8 to 40 ft | dusk & dawn | Secondary point (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 10 to 40 ft | dawn | Deep basin (40 ft) | White tube jig, Airplane jig |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for northern pike in spring. 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 | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Secondary point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Secondary point (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (3 ft) | Tip-ups, Large jigging spoon |
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Break off the point is the standout, a drop-off at roughly 23 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| 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 (23 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 (23 ft) | Jigging spoon, Tube jig (white) |
