Lake depth chart

89-acre lake in Kenora District, Ontario. The lake tops out around 20 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 1987 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 90 acres, worked by 2.6 miles of shoreline. With a 1.9 development index there's bank structure worth casting at, in moderation. Roughly 93% of the water is 15 ft or less, the band where the food chain lives. Call it 0.8 mi long by 0.5 mi wide at the broadest reach. Kenora District claims this one. If the bite dies, Unnamed Lake is 1 mi to the northeast.
Start shallow in spring: cisco (lake herring) sit in 5 to 20 ft that time of year. They don't go far with the seasons — 6 to 20 ft covers summer, 6 to 20 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 19 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic 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 | 5 to 20 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (19 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 6 to 20 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (19 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 4 to 20 ft chart-limited; documented 5 to 25 ft | dusk & dawn | Break off the point (11 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 6 to 20 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (19 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. Break off the point is the standout, a drop-off at roughly 11 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Secondary point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (11 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (11 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (19 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

Unnamed Lake is about 20 ft (6 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1987 (a transect sounding survey).
Anglers target cisco (lake herring), walleye, yellow perch on Unnamed Lake.
Deep basin is the top-rated area: a deep basin in about 19 ft of water that rates prime for cisco (lake herring) in spring. The interactive chart above rates every spot for each 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.
