6,640-acre lake near Gregoire Lake Estates. The lake tops out around 23 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 6,626 acres wrapped in 18.9 miles of bank — one island included. A middling shoreline index (1.7) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 69% of this chart. Call it 5.8 mi long by 3.4 mi wide at the broadest reach. Division No. 16 claims this one. Its nearest charted neighbour, Lac La Loche, is 60 mi to the east.
Early season burbot use the shallows, holding in 7 to 23 ft. Even in summer they hold at 7 to 23 ft; winter keeps them in 6 to 23 ft. The chart's best answer is Deep basin — deep basin, 23 ft, prime for spring. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 23 ft | night & dusk | Deep basin (23 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 7 to 23 ft | night & midday | Deep basin (23 ft) | Heavy jig + cut bait |
| Fall | 7 to 23 ft | night & dusk | Deep basin (23 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 6 to 23 ft | night & dusk | Deep basin (23 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Spring puts cisco (lake herring) in skinny water — 6 to 23 ft is the zone. Summer fish stay in 7 to 23 ft, and winter fish hold in 7 to 23 ft. Deep basin is the standout, a deep basin at roughly 23 ft, rated prime for spring cisco (lake herring). Plan around early morning in the warm months. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 23 ft | dawn & dusk | Deep basin (23 ft) | Small silver spoon, Tiny swim jig (white) |

Spring puts lake whitefish in skinny water — 7 to 23 ft is the zone. Summer fish stay in 7 to 23 ft, and winter fish hold in 7 to 23 ft. Deep basin is the standout, a deep basin at roughly 23 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 23 ft | midday & dawn | Break off the point (23 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 7 to 23 ft | dawn | Deep basin (23 ft) | Blade bait vertical, Small jigging spoon |

Spring northern pike on Gregoire Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| 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 | Shallow feeding flat (20 ft) | Bucktail, Weedless spoon over cabbage |

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 7 to 23 ft, and winter fish settle into 7 to 23 ft. The spot to know is Break off the point, a drop-off in about 23 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 7 to 23 ft | dusk & dawn | Break off the point (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 7 to 23 ft | dusk & night | Break off the point (23 ft) | Jigging rap, Jig + big minnow |
| Winter | 7 to 23 ft | dusk & dawn | Deep basin (23 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 7 to 23 ft, wintering in 7 to 23 ft. Spring yellow perch concentrate at Back-bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
