897-acre lake near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 28 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. 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. About 76% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 1.6 mi of water from one end to the other, 1.2 mi at the beam. You'll find it in Wells County. The nearest mapped water is Silver Lake WMA, 7 mi to the northwest.
Spring walleye on Monson Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 8 to 28 ft, and by winter most fish are in 8 to 28 ft. The chart's best answer is Deep basin — deep basin, 28 ft, prime for winter. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
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 | 4 to 15 ft | dusk & dawn | Main-lake point (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 28 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (28 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 28 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (28 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 28 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (28 ft) | Jigging spoon + minnow head, Rattle bait |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is an 8 to 28 ft game here, winter an 8 to 28 ft one. The chart's best answer is Shallow bay flat — weed flat, 4 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
