989-acre lake in Sudbury District, Ontario. The lake tops out around 26 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 a transect sounding survey by the Ontario MNRF. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 993 acres wrapped in 32.2 miles of bank, broken up by 64 islands. That shoreline is heavily fingered (development index 7.3) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 97% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 3.9 mi with a 1.4-mi widest point. It sits in Sudbury District. If the bite dies, Schou Lake is 2 mi to the northwest.
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 8 to 26 ft; cold water stacks them in 8 to 26 ft. Deep basin is the standout, a deep basin at roughly 26 ft, rated prime for winter walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
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 | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 26 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (26 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 26 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (26 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 26 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (26 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 8 to 26 ft; cold water stacks them in 8 to 26 ft. Top water on the chart: Deep basin, a deep basin in the 26 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm 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 | 3 to 12 ft | midday & dawn | Back-bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 26 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Back-bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (18 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow feeding flat (18 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (2 ft) | Tip-ups, Large jigging spoon |

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 Schist Lake specifically, so confirm the current rules before you fish.

Schist Lake is about 26 ft (8 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target walleye, yellow perch, northern pike on Schist 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 26 ft of water that rates prime for walleye in winter. Every other rated spot, per species and season, is on the map above.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
