897-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 28 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. Species by species, here's what the data says the year looks like.
Drawn out, this is 897 acres of water rimmed by 4.5 miles of bank. Nearly circular (index 1.1), so the story is the bottom, not the bank.

The nearest mapped water is Silver Lake WMA, 7 mi to the northwest.
