11,075-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 23 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.
The drawn water covers 11,076 acres wrapped in 17.2 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 61% of this chart. Call it 5.7 mi long by 5.5 mi wide at the broadest reach. Kidder County claims this one. Its nearest charted neighbour, Fresh Lake, is 4 mi to the southwest.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 7 to 23 ft, and winter fish settle into 7 to 23 ft. The spot to know is Gravel shoal, a gravel shoal in about 4 ft of water that rates prime for walleye in spring. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 7 to 23 ft | dusk & dawn | Break off the point (18 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 7 to 23 ft | dusk & night | Break off the point (18 ft) | Jigging rap, Jig + big minnow |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 7 to 23 ft, wintering in 7 to 23 ft. Spring yellow perch concentrate at Back-bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
