76-acre lake in Algoma District, Ontario. The lake tops out around 40 ft. 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.
Gashen Lake maps at 76 acres behind 3.2 miles of shoreline. That shoreline is heavily fingered (development index 2.6) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 66% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 0.6 mi with a 0.4-mi widest point. Algoma District claims this one. Lolligag Lake sits 1 mi west — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 24 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 (13 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (24 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
