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 Yearleys P. 3: what the data says

15-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 16 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 1971, a decades-old survey (an MNRF lake survey). Species by species, here's what the data says the year looks like.

Drawn out, this is 15 acres of water rimmed by 0.8 miles of bank. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Call it 0.3 mi long. The water lies in Muskoka District Municipality. Closest neighbour on DepthScout: Axe Lake, 3 mi west of here.
