361-acre lake in Kenora District, Ontario. The lake tops out around 69 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Tull Lake draws 362 acres inside 10.1 miles of shoreline. An index of 3.8 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 38% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 3.2 mi, about 0.7 mi across. You'll find it in Kenora District. The nearest mapped water is Lye Lake, 3 mi to the northeast.
When the water first warms, lake whitefish slide up into 15 to 45 ft. Summer is a 21 to 69 ft game here, winter a 21 to 69 ft one. Start at Deep basin. It's a deep basin holding about 59 ft of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
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 | 15 to 45 ft | midday & dawn | Break off the point (31 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 21 to 69 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (59 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (31 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 21 to 69 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (59 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 31 ft that grades prime for fall. In summer the feeding windows fall in 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 | Main-lake point (17 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (31 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (31 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (31 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Tull Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. The feeding windows run 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 | Break off the point (31 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (31 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (31 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. 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 21 to 69 ft that time of year. They don't go far with the seasons — 21 to 69 ft covers summer, 15 to 60 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 59 ft range, prime in spring. Fish it in after dark and midday and you'll meet the bite. 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 | 21 to 69 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (59 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 21 to 69 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (59 ft) | Heavy jig + cut bait |
| Fall | 21 to 69 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (59 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (59 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
