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 Pat L.: what the data says

5-acre lake in Sudbury District, Ontario. The lake tops out around 25 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 1961, a decades-old survey (an MNRF lake survey). What follows comes from the same scoring engine that paints the spots above.

The outline encloses 5 acres, worked by 0.3 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. It sits in Sudbury District. Mike L. sits 0 mi south — the closest neighbouring chart.
