605-acre lake near Eastman. The lake tops out around 204 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 598 acres wrapped in 8.5 miles of bank. The 2.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 4% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 3.9 mi end to end and 0.6 mi across at its widest. It sits in Memphrémagog MRC. If the bite dies, Lac des Français is 1 mi to the north.

Spring lake trout on Lac Bowker hold shallow, usually 10 to 40 ft. By summer they slide out to 50 to 120 ft, and by winter most fish are in 20 to 80 ft. The chart's best answer is Secondary point — point, 37 ft, prime for spring. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Secondary point (37 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Deep basin (199 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Secondary point (37 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Break off the point (15 ft) | White tube jig, Airplane jig |
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 15 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (4 ft) | Inline spinner (silver), Small spoon |
| Été | 8 to 30 ft | dawn & dusk | Break off the point (15 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Automne | 10 to 35 ft | dawn & dusk | Secondary point (37 ft) | Casting spoon, Jerkbait over shoals |
| Hiver | 8 to 40 ft | dawn | Break off the point (15 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: brown trout in 3 to 25 ft. Midsummer fish sit out in 25 to 60 ft before dropping to 5 to 35 ft for winter. The spot to know is Break off the point, a drop-off in about 15 ft of water that rates prime for brown trout in winter. Plan around after dark and early morning in the warm months. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (4 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Été | 25 to 60 ft | night & dawn | Secondary point (37 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Automne | 5 to 30 ft | dusk & dawn | Main-lake point (4 ft) | Jerkbait over gravel, Casting spoon |
| Hiver | 5 to 35 ft | dawn | Break off the point (15 ft) | Jigging spoon, Small stickbait (slow) |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 40 to 90 ft, and winter fish settle into 25 to 70 ft. Break off the point is the standout, a drop-off at roughly 15 ft, rated prime for spring lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Break off the point (15 ft) | Small jig + waxworm, Blade bait (small) |

In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 40 to 80 ft, and winter fish settle into 20 to 60 ft. Break off the point is the standout, a drop-off at roughly 15 ft, rated good for spring cisco (lake herring). Time it for early morning. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.

The spot to know is Break off the point, a drop-off in about 15 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
