151-acre reservoir 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. Below is the species-by-species picture, pulled from the same data the map uses.
Tioga Dam maps at 151 acres behind 2.1 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. 70% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.9 mi, about 0.4 mi across. Williams County claims this one. If the bite dies, White Earth Dam is 10 mi to the northeast.
Spring northern pike on Tioga Dam hold shallow, usually 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Shallow bay flat — weed flat, 4 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (21 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Secondary point (7 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 8 to 28 ft, wintering in 8 to 28 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 28 ft | dawn | Deep basin (27 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 28 ft | midday | Deep basin (27 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 28 ft | midday & dawn | Deep basin (27 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring bluegill on Tioga Dam hold shallow, usually 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down 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. The feeding windows run early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.
| 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 | Deep basin (27 ft) | Tungsten ice jig + plastic, Tiny spoon |
Structure-wise the chart holds 7 features, led in depth by Deep basin at roughly 27 ft.
