31-acre lake in Algoma District, Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 2002 (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 32 acres, worked by 2.2 miles of shoreline. The 2.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 72% of this chart. Call it 0.6 mi long by 0.4 mi wide at the broadest reach. Algoma District claims this one. If the bite dies, Emily Murphy L. is 0 mi to the northeast.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 20 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 20 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
6 pieces of structure are mapped here — Deep basin, around 20 ft, is the deepest of them.
