19,710-acre lake near Bentley. The lake tops out around 25 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 19,710 acres wrapped in 34.7 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. About 42% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 11.8 mi with a 4.5-mi widest point. Division No. 8 claims this one. Sylvan Lake sits 14 mi southwest — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 8 to 25 ft, wintering in 8 to 25 ft. Top water on the chart: Gravel shoal, a gravel shoal in the 4 ft range, prime in spring. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 25 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (25 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 25 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (25 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 25 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (25 ft) | Jigging spoon + minnow head, Rattle bait |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Sharp break first on the milk run — a drop-off near 10 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Sharp break (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow feeding flat (17 ft) | Tip-ups, Large jigging spoon |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 25 ft. Deep basin is the standout, a deep basin at roughly 25 ft, rated prime for fall yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Gravel shoal (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 25 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 25 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (25 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 25 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (25 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, lake whitefish run shallow here, mostly 8 to 25 ft. Summer keeps them at 8 to 25 ft, and they winter in 8 to 25 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 25 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 25 ft chart-limited; documented 15 to 45 ft | midday & dawn | Gravel shoal (5 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 8 to 25 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (25 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 7 to 25 ft chart-limited; documented 8 to 30 ft | dusk | Gravel shoal (5 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 8 to 25 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (25 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring burbot on Gull Lake hold shallow, usually 8 to 25 ft. Depth-wise the year is flat: 8 to 25 ft in summer, 6 to 25 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 25 ft that grades prime for spring. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.

Gull Lake is about 25 ft (8 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target walleye, northern pike, yellow perch, lake whitefish, burbot on Gull Lake.
Gravel shoal is the top-rated area: a gravel shoal in about 4 ft of water that rates prime for walleye in spring. The interactive chart above rates every spot for each species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
