803-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 11 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.
On the chart, Lake Isabel draws 803 acres inside 4.1 miles of shoreline. Nearly circular (index 1), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 1.5 mi, about 1.1 mi across. The water lies in Kidder County. Closest neighbour on DepthScout: Sibley Lake, 9 mi north of here.
Come spring, look for walleye tight to the bank in 3 to 11 ft. Through summer count on 3 to 11 ft; the winter hold is 3 to 11 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
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 | 3 to 11 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Old creek channel (9 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 11 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 11 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 11 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (11 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 3 to 11 ft, and winter fish settle into 3 to 11 ft. The spot to know is Break off the point, a drop-off in about 10 ft of water that rates prime for northern pike in fall. 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 (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 3 to 11 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Bucktail, Weedless spoon over cabbage |

| Winter | 3 to 11 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
Come spring, look for yellow perch tight to the bank in 3 to 11 ft. Through summer count on 3 to 11 ft; the winter hold is 3 to 11 ft. Start at Deep basin. It's a deep basin holding about 11 ft of water and rates prime come fall. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.

Spring puts common carp in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 2 to 11 ft; cold water stacks them in 3 to 11 ft. Deep basin is the standout, a deep basin at roughly 11 ft, rated prime for winter common carp. Plan around early morning and the evening in the warm months.
