36-acre lake in Cochrane District, Ontario. The lake tops out around 59 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 1981 (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 36 acres wrapped in 1.7 miles of bank, broken up by an island. A middling shoreline index (2) gives it some bays to work without being a maze. About 63% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.6 mi with a 0.3-mi widest point. Cochrane District claims this one. If the bite dies, Mile 30 Lake is 1 mi to the southwest.
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 18 to 59 ft before dropping to 18 to 59 ft for winter. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 56 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
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 (9 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 18 to 59 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (56 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (9 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 18 to 59 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (56 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 18 to 59 ft before dropping to 18 to 59 ft for winter. Summer cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 56 ft. Fish it in early morning and you'll meet the bite. 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 (9 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 18 to 59 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (56 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (9 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 18 to 59 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (56 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 9 ft range, prime in fall. Time it for the evening and early morning. 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 | Main-lake point (11 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Main-lake point (11 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (9 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. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 9 ft, rated prime for spring yellow perch. Time it for early morning. 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 (9 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (9 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (9 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 9 ft that grades prime for winter. In summer the feeding windows fall in 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 (9 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (9 ft) | Tip-ups, Large jigging spoon |
E-11 Lake carries 5 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 56 ft down.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to E-11 Lake specifically, so confirm the current rules before you fish.

E-11 Lake is about 59 ft (18 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1981 (a transect sounding survey).
Anglers target lake whitefish, cisco (lake herring), walleye, yellow perch, northern pike on E-11 Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Deep basin is the top-rated area: a deep basin in about 56 ft of water that rates prime for lake whitefish in summer. The interactive chart above rates every spot for each species and season.
For lake whitefish, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on E-11 Lake is regulated by the Ontario fishing regulations (FMZ summary). Check the official Ontario regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
