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 Yarrow L. 10: what the data says

64-acre lake in Timiskaming District, Ontario. The lake tops out around 25 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Every species below gets its seasonal read from the same numbers driving the chart.

Drawn out, this is 65 acres of water rimmed by 1.5 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 76% of the surface on the model — that's where the groceries are. The basin spans about 0.5 mi end to end and 0.3 mi across at its widest. The water lies in Timiskaming District. Closest neighbour on DepthScout: James L., 1 mi south of here.

Brook Trout fishing at Yarrow L. 10

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 8 to 25 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 21 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
