12,045-acre lake in Kenora District, Ontario. The lake tops out around 33 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 1975, a decades-old survey (an MNRF lake survey). What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Dinorwic Lake runs 12,100 acres with 124.7 miles of edge, with 114 islands in the mix. That shoreline is heavily fingered (development index 8.1) — bays, points and pockets everywhere, which multiplies the fishable edge. About 66% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 11.1 mi end to end and 6.6 mi across at its widest. You'll find it in Kenora District. The nearest mapped water is Paulson Lake, 2 mi to the west.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Come spring, look for lake whitefish tight to the bank in 10 to 33 ft. Through summer count on 10 to 33 ft; the winter hold is 10 to 33 ft. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in summer. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
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 33 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (16 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 10 to 33 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (26 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Gravel shoal (5 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 10 to 33 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (26 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for cisco (lake herring) tight to the bank in 8 to 33 ft. Through summer count on 10 to 33 ft; the winter hold is 10 to 33 ft. If you only fish one area, make it Deep basin: a deep basin around 26 ft that scores prime in spring. Best bite is early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 33 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (26 ft) | Small silver spoon, Tiny swim jig (white) |

Spring walleye on Dinorwic Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 10 to 33 ft, and by winter most fish are in 10 to 33 ft. The chart's best answer is Gravel shoal — gravel shoal, 5 ft, prime for spring. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 10 to 33 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (16 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 10 to 33 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (16 ft) | Jigging rap, Jig + big minnow |
| Winter | 10 to 33 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (26 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for sauger tight to the bank in 4 to 18 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 10 to 33 ft. Start at Deep basin. It's a deep basin holding about 26 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A bottom bouncer + crawler or a 3-way rig with stickbait is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Gravel shoal (5 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |

| Winter | 10 to 33 ft chart-limited; documented 15 to 45 ft | dusk | Deep basin (26 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 10 to 33 ft one. The chart's best answer is Weed flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.

In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Weed flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Weed flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (16 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (16 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Weed flat (5 ft) | Tip-ups, Large jigging spoon |
