896-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 19 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. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 895 acres, worked by 5.7 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. About 90% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 2.6 mi with a 0.8-mi widest point. It sits in McLean County. Its nearest charted neighbour, Lake Brekken, is 11 mi to the northeast.
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 6 to 19 ft before dropping to 6 to 19 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 13 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.
