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

Fall shiner runActive window

Typical here: Sep 1 – Oct 31 · same push on the Ontario side — Simcoe's shiners migrate shallow as the water cools, and the predators ride with them

adultdaylight for the jig bite; after dark the shiners stack under dock lights with walleyes and pike mixed right in — follow the bait, not the spot — millions of shiners move together and the predators ride with them; silver profile and flash matter

Concentrates hard but travels — the school (and the walleyes under it) can be off a river mouth one week and miles upriver the next.

Jig-and-minnow is the event's signature — a frozen emerald shiner on a 1/4 oz jig drifted along the run; silver jerkbaits and trolled crankbaits take the roaming fish; blade baits under the schools.

The event happens over river mouths and the first miles upriver, warming shallow shorelines, and rocky points where the displaced bait stacks

Fishing Henry Lake: what the data says

62-acre lake in Parry Sound District, Ontario. The lake tops out around 18 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.

Henry Lake maps at 61 acres behind 1.6 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. Parry Sound District claims this one. Its nearest charted neighbour, Horn Lake, is 2 mi to the east.

Smallmouth Bass fishing at Henry Lake

When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 5 to 18 ft, and by winter most fish are in 5 to 18 ft. If you only fish one area, make it Break off the point: a drop-off around 3 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	dawn & dusk	Main-lake point (1 ft)	Ned rig, Tube jig
Summer	5 to 18 ft	dawn & dusk	Break off the point (3 ft)	Drop shot (goby/minnow), Ned rig
Fall	5 to 18 ft	midday & dawn	Break off the point (3 ft)	Jerkbait, Blade bait
Winter	5 to 18 ft	midday	Break off the point (3 ft)	Blade bait, Hair jig
