Rating depth structure for walleye.
Recent public catches load as you reach this section.
135-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 21 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.
Gravel Lake maps at 135 acres behind 1.8 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 64% of the water is 15 ft or less, the band where the food chain lives. Figure 0.7 mi of water from one end to the other, 0.4 mi at the beam. It sits in Rolette County. Its nearest charted neighbour, Upsilon Lake, is 1 mi to the northwest.
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 6 to 21 ft before dropping to 6 to 21 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 8 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
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 | Secondary point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 21 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 21 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 21 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (21 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 6 to 21 ft before dropping to 6 to 21 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. 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 (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 21 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 21 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (21 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 21 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (21 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 6 to 21 ft. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.

| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (6 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |

6 pieces of structure are mapped here — Deep basin, around 21 ft, is the deepest of them.

Gravel Lake is about 21 ft (6 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, yellow perch, northern pike, bluegill on Gravel Lake.
Break off the point is the top-rated area: a drop-off in about 8 ft of water that rates prime for walleye in fall. The map above holds the full rated-spot list for every 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.
