Hatch outlook

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 Heaslip Lake: what the data says

37-acre lake in Parry Sound District, Ontario. The lake tops out around 56 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What the data behind the map says about each species, season by season:

The drawn water covers 37 acres wrapped in 1.3 miles of bank. With a 1.5 development index there's bank structure worth casting at, in moderation. Roughly 34% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. Parry Sound District claims this one. Its nearest charted neighbour, Long Lake, is 1 mi to the southwest.

Yellow Perch fishing at Heaslip Lake

Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Break off the point, a drop-off in about 25 ft of water that rates prime for yellow perch in summer. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	midday & dawn	open water	Small jig + curly tail, Perch-pattern micro crank
Summer	10 to 30 ft	dawn	Break off the point (25 ft)	Drop-shot micro plastics, Small spoon tipped with worm
