124-acre reservoir near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 32 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. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 124 acres, worked by 2.1 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 54% of the surface — that's where the groceries are. Figure 1 mi of water from one end to the other, 0.3 mi at the beam. It sits in Williams County. If the bite dies, Tioga Dam is 12 mi to the south.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 10 to 32 ft before dropping to 10 to 32 ft for winter. The spot to know is Break off the point, a drop-off in about 21 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (9 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 10 to 32 ft | dusk & dawn | Break off the point (21 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 10 to 32 ft | dusk & night | Break off the point (21 ft) | Jigging rap, Jig + big minnow |
| Winter | 10 to 32 ft | dusk & dawn | Deep basin (32 ft) | Jigging spoon + minnow head, Rattle bait |
Early season crappie use the shallows, holding in 2 to 8 ft. Summer is a 10 to 25 ft game here, winter a 10 to 32 ft one. The chart's best answer is Deep basin — deep basin, 32 ft, prime for winter. Best bite is early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (21 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (21 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 10 to 32 ft | midday | Deep basin (32 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season bluegill use the shallows, holding in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Break off the point (21 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 6 to 32 ft. If you only fish one area, make it Break off the point: a drop-off around 21 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (21 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 32 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
