255-acre lake in Rainy River District, Ontario. The lake tops out around 105 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Flora Lake runs 255 acres with 5.1 miles of edge, with a single island in the mix. A development index of 2.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 12% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 1 mi long by 0.9 mi wide at the broadest reach. The water lies in Rainy River District. For a second option, Banning Lake lies 1 mi south.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 32 to 105 ft, and winter fish settle into 20 to 80 ft. The spot to know is Deep basin, a deep basin in about 89 ft of water that rates prime for lake trout in summer. Warm-month bites cluster around early morning. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
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 | 10 to 40 ft | dawn & dusk | Main-lake point (26 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 32 to 105 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (89 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (26 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (89 ft) | White tube jig, Airplane jig |
Spring yellow perch on Flora Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Shallow bay flat — feeding flat, 6 ft, prime for spring. 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 | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
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. Spring northern pike concentrate at Shallow bay flat, a prime-rated feeding flat around 6 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 (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: burbot sit in 25 to 70 ft that time of year. Summer pushes them deeper, 32 to 105 ft, and winter fish settle into 15 to 60 ft. The spot to know is Deep basin, a deep basin in about 89 ft of water that rates prime for burbot in summer. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.
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 | 25 to 70 ft | night & dusk | Deep basin (89 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 32 to 105 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (89 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (89 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | open water | Glow tungsten + cut bait, Rattle spoon + minnow head |
