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 Shunsby Lake: what the data says

94-acre lake in Sudbury District, Ontario. The lake tops out around 42 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.

The outline encloses 94 acres, worked by 3.9 miles of shoreline. That shoreline is heavily fingered (development index 2.9) — bays, points and pockets everywhere, which multiplies the fishable edge. About 76% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 1.3 mi long by 0.3 mi wide at the broadest reach. Sudbury District claims this one. If the bite dies, Sawbill Lake is 4 mi to the south.

Northern Pike fishing at Shunsby Lake

Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 5 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 8 ft	midday & dawn	Shallow bay flat (5 ft)	#5 inline spinner, Spoon (red/white)
Summer	8 to 20 ft	dawn & dusk	Break off the point (19 ft)	Bucktail, Weedless spoon over cabbage
Fall	6 to 18 ft	midday & dawn	Shallow bay flat (5 ft)	Big rubber (Bull Dawg style), Husky-style jerkbait
Winter	5 to 15 ft	midday	Shallow bay flat (5 ft)	Tip-ups, Large jigging spoon
