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 Betty Lake: what the data says

248-acre lake in Sudbury District, Ontario. The lake tops out around 52 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What follows comes from the same scoring engine that paints the spots above.

Traced from the shoreline, Betty Lake runs 249 acres with 6.4 miles of edge. An index of 2.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 75% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 1 mi, about 0.9 mi across. You'll find it in Sudbury District. The nearest mapped water is Sawbill Lake, 2 mi to the west.

Lake Whitefish fishing at Betty Lake

Spring lake whitefish on Betty Lake hold shallow, usually 15 to 45 ft. They move out to 16 to 52 ft in summer and finish the year down in 16 to 52 ft. Put Deep basin first on the milk run — a deep basin near 44 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.

Season	Depth	Best window	Start at	Go-to baits
Spring	15 to 45 ft	midday & dawn	Break off the point (23 ft)	Small jig + waxworm, Blade bait (small)
Summer	16 to 52 ft	dawn	Deep basin (44 ft)	Blade bait vertical, Small jigging spoon
Fall	8 to 30 ft	dusk	Break off the point (23 ft)	Small spoon (gold), Jig + plastic larva
Winter	16 to 52 ft	midday & dawn	Deep basin (44 ft)	Jigging spoon + bead chain, Tungsten jig + waxie

Northern Pike fishing at Betty Lake

The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

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