1,181-acre lake in Kenora 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 the Ontario MNRF survey of 1982 (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
Bradden Lake maps at 1,187 acres behind 21.8 miles of shoreline, broken up by 10 islands. A development index of 4.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 84% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 3.6 mi long by 1.6 mi wide at the broadest reach. It sits in Kenora District. Wapikopa Lake sits 11 mi northeast — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 8 to 26 ft before dropping to 8 to 26 ft for winter. The spot to know is Deep basin, a deep basin in about 26 ft of water that rates prime for walleye in winter. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
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 (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 26 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Secondary point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 26 ft chart-limited; documented 12 to 40 ft | dusk & night | Secondary point (8 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 |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 4 ft, prime for spring. Best bite is 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 (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (19 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: lake sturgeon sit in 3 to 15 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 after dark and the evening and you'll meet the bite.
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 15 ft | dusk & night | open water | |
| Summer | 8 to 26 ft chart-limited; documented 15 to 40 ft | night & dusk | Deep basin (26 ft) | |
| Fall | 8 to 26 ft chart-limited; documented 15 to 45 ft | dusk | Deep basin (26 ft) | |
| Winter | 8 to 26 ft chart-limited; documented 20 to 60 ft | midday | Deep basin (26 ft) |
Bradden Lake carries 7 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 26 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 Bradden Lake specifically, so confirm the current rules before you fish.

Bradden Lake is about 26 ft (8 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1982 (a transect sounding survey).
Anglers target walleye, northern pike, lake sturgeon on Bradden 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. Scroll up to the map for the complete spot list by 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.
