23-acre lake in Algoma District, Ontario. The lake tops out around 31 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 1963, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 23 acres, worked by 2 miles of shoreline, with a single island in the mix. An index of 2.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 90% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. Algoma District claims this one. Wanamaker Lake sits 2 mi east — the closest neighbouring chart.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Deep basin — deep basin, 27 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (27 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (5 ft) | Small jigging spoon, Tungsten jig + plastic |
5 pieces of structure are mapped here — Deep basin, around 27 ft, is the deepest of them.
