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 Ivans L.: what the data says

17-acre lake in Algoma District, Ontario. The lake tops out around 32 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 1981 (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.

The drawn water covers 17 acres wrapped in 1.1 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. 76% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.5 mi. Algoma District claims this one. Proctor Lake 3 sits 0 mi south — the closest neighbouring chart.
