803-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 11 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. 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.

|---|---|---|---|---|
