677-acre lake in Kenora District, Ontario. The lake tops out around 23 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 1983 (an MNRF lake survey). What the data behind the map says about each species, season by season:
Drawn out, this is 677 acres of water rimmed by 7.5 miles of bank. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. Figure 2 mi of water from one end to the other, 0.9 mi at the beam. You'll find it in Kenora District. The nearest mapped water is Bawlb L., 2 mi to the north.
Come spring, look for cisco (lake herring) tight to the bank in 6 to 23 ft. Through summer count on 7 to 23 ft; the winter hold is 7 to 23 ft. If you only fish one area, make it Deep basin: a deep basin around 13 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.
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 | 6 to 23 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (13 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 7 to 23 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (13 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 23 ft chart-limited; documented 5 to 25 ft | dusk & dawn | Break off the point (3 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 7 to 23 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (13 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring walleye on Sidace Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 7 to 23 ft, and by winter most fish are in 7 to 23 ft. The chart's best answer is Deep basin — deep basin, 13 ft, prime for winter. 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 | Break off the point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 7 to 23 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (13 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 7 to 23 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (13 ft) | Jigging rap, Jig + big minnow |
| Winter | 7 to 23 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (13 ft) | Jigging spoon + minnow head, Rattle bait |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 7 to 23 ft game here, winter a 7 to 23 ft one. The chart's best answer is Deep basin — deep basin, 13 ft, prime for fall. 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.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 23 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 23 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (13 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 23 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (13 ft) | Tungsten jig + spikes, Rattle spoon (small) |
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 Shallow bay flat, a prime-rated weed flat around 1 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 | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: burbot in 7 to 23 ft. The depth story barely changes: 7 to 23 ft through summer, 6 to 23 ft in winter. The spot to know is Deep basin, a deep basin in about 13 ft of water that rates prime for burbot in spring. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.

6 pieces of structure are mapped here — Deep basin, around 13 ft, is the deepest of them.

Sidace Lake is about 23 ft (7 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1983 (an MNRF lake survey).
Anglers target cisco (lake herring), walleye, yellow perch, northern pike, burbot on Sidace Lake.
Deep basin is the top-rated area: a deep basin in about 13 ft of water that rates prime for cisco (lake herring) in spring. The map above holds the full rated-spot list for every species and season.
For cisco (lake herring), 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.
