2,085-acre lake in Kenora District, Ontario. The lake tops out around 108 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (an MNRF lake survey). What the data behind the map says about each species, season by season:
The drawn water covers 2,090 acres wrapped in 24.2 miles of bank — 2 islands included. The 3.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 45% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 5.8 mi long by 1.7 mi wide at the broadest reach. It sits in Kenora District. If the bite dies, Embryo Lake is 2 mi to the northeast.
Spring lake trout on Telescope Lake hold shallow, usually 10 to 40 ft. By summer they slide out to 32 to 108 ft, and by winter most fish are in 20 to 80 ft. The chart's best answer is Deep basin — deep basin, 97 ft, prime for summer. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
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 | Secondary point (3 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 32 to 108 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (97 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (3 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (97 ft) | White tube jig, Airplane jig |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 40 to 90 ft, and winter fish settle into 25 to 70 ft. Deep basin is the standout, a deep basin at roughly 97 ft, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Feeding flat (27 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Deep basin (97 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (2 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Feeding flat (27 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 40 to 80 ft, and winter fish settle into 20 to 60 ft. Deep basin is the standout, a deep basin at roughly 97 ft, rated good for summer cisco (lake herring). Time it for early morning. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (2 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (97 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (2 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | open water | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 20 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 2 ft of water that rates good 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 | Secondary point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Feeding flat (27 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (2 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | open water | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| 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 | 10 to 30 ft | dawn | Feeding flat (27 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (2 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Feeding flat (27 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 4 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage 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) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow feeding flat (6 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 |
