563-acre lake in Kenora District, Ontario. The lake tops out around 3 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. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Cordick Lake draws 566 acres inside 14.2 miles of shoreline, broken up by 11 islands. A development index of 4.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 1.9 mi long by 1.5 mi wide at the broadest reach. The water lies in Kenora District. For a second option, Assin Lake lies 13 mi north.
Early season walleye use the shallows, holding in 1 to 3 ft. Even in summer they hold at 1 to 3 ft; winter keeps them in 1 to 3 ft. The chart's best answer is Deep basin — deep basin, 3 ft, good for winter. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
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 | 1 to 3 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 1 to 3 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Main-lake point (2 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 1 to 3 ft chart-limited; documented 12 to 40 ft | dusk & night | Main-lake point (2 ft) | Jigging rap, Jig + big minnow |
| Winter | 1 to 3 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (3 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts northern pike in skinny water — 1 to 3 ft is the zone. Summer fish stay in 1 to 3 ft, and winter fish hold in 1 to 3 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 3 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 1 to 3 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (2 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 1 to 3 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (2 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 1 to 3 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
Spring lake sturgeon on Cordick Lake hold shallow, usually 1 to 3 ft. Depth-wise the year is flat: 1 to 3 ft in summer, 1 to 3 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 3 ft that grades good for fall. The feeding windows run after dark and the evening.

Cordick Lake is about 3 ft (1 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target walleye, northern pike, lake sturgeon on Cordick 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 3 ft of water that rates good for walleye in winter. The interactive chart above rates every spot for each species and season.
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.
