Banana Lake Depth Map & Fishing Spots (Algoma District, ON)

Hatch outlook

Hopper & ant season (windward banks)Active window

Typical here: Jul 1 – Sep 15 · hoppers peak July–August; winged-ant falls show up on warm humid afternoons — a wind event, not a hatch

adultwarm, breezy afternoons, roughly 1–5pm — slap the imitation down hard — the splat is the trigger — then wait; count to three after the rise before setting

Work the windward bank on breezy summer afternoons — that's where the food is. Casting-bubble-and-hopper is the direct translation; otherwise run small topwaters and inline spinners tight along the grass edges and blowdown banks in the afternoon warmth.

The event happens over windward grassy banks, overhanging brush and blowdowns — wherever the breeze dumps the bugs

Fishing Banana Lake: what the data says

93-acre lake in Algoma District, Ontario. The lake tops out around 30 ft. The depth data here comes from the Ontario MNRF survey of 1972, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.

Traced from the shoreline, Banana Lake runs 94 acres with 3.7 miles of edge — 3 islands included. An index of 2.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 68% of this chart. End to end it runs roughly 1.1 mi, about 0.3 mi across. You'll find it in Algoma District. For a second option, South Lake lies 1 mi west.

Brook Trout fishing at Banana Lake

The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 29 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
