22,200-acre lake near Rochon Sands. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
On the chart, Buffalo Lake draws 22,146 acres inside 68.5 miles of shoreline, broken up by 7 islands. With a shoreline index of 3.3, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 81% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 11.8 mi end to end and 7.4 mi across at its widest. The water lies in Division No. 7. For a second option, Red Deer Lake lies 17 mi north.
Start shallow in spring: burbot sit in 6 to 20 ft that time of year. They don't go far with the seasons — 6 to 20 ft covers summer, 5 to 20 ft covers winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for burbot in spring. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 20 ft | night & dusk | Deep basin (20 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 6 to 20 ft | night & midday | Deep basin (20 ft) | Heavy jig + cut bait |
| Fall | 6 to 20 ft | night & dusk | Deep basin (20 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 5 to 20 ft | night & dusk | Deep basin (20 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Fall northern pike concentrate at Break off the point, a prime-rated drop-off around 15 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Feeding flat (9 ft) | Tip-ups, Large jigging spoon |
Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 6 to 20 ft game here, winter a 6 to 20 ft one. The chart's best answer is Gravel shoal — gravel shoal, 4 ft, prime for spring. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| 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 | 6 to 20 ft | dusk & dawn | Break off the point (15 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft | dusk & night | Break off the point (15 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Buffalo Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 6 to 20 ft. The chart's best answer is Deep basin — deep basin, 20 ft, prime for fall. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Feeding flat (9 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
