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 Mud Lake: what the data says

39-acre lake in Dufferin County, Ontario. The lake tops out around 5 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 39 acres of water rimmed by 1.5 miles of bank. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 0.6 mi end to end and 0.2 mi across at its widest. You'll find it in Dufferin County. Closest neighbour on DepthScout: Caledon Lake, 5 mi east of here.

Northern Pike fishing at Mud Lake

In spring, northern pike run shallow here, mostly 1 to 5 ft. Summer keeps them at 2 to 5 ft, and they winter in 2 to 5 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 5 ft	midday & dawn	Shallow bay flat (3 ft)	#5 inline spinner, Spoon (red/white)
Summer	2 to 5 ft	dawn & dusk	Shallow bay flat (3 ft)	Bucktail, Weedless spoon over cabbage
Fall	2 to 5 ft	midday & dawn	Shallow bay flat (3 ft)	Big rubber (Bull Dawg style), Husky-style jerkbait
Winter	2 to 5 ft	midday	Shallow bay flat (3 ft)	Tip-ups, Large jigging spoon

Pumpkinseed fishing at Mud Lake

Come spring, look for pumpkinseed tight to the bank in 1 to 5 ft. Through summer count on 1 to 5 ft; the winter hold is 2 to 5 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 5 ft	midday & dusk	Shallow bay flat (3 ft)	Micro jig under a float, Tiny beetle-spin
Summer	1 to 5 ft	dusk & dawn	Shallow bay flat (3 ft)	Micro tube, Sponge spider (fly)
Fall	1 to 5 ft	dusk & dawn	Shallow bay flat (3 ft)	Micro jig + waxworm, Small spoon tipped
Winter	2 to 5 ft	dawn	Shallow bay flat (3 ft)	Tungsten ice jig + plastic, Tiny spoon

Brown Bullhead fishing at Mud Lake

Start shallow in spring: brown bullhead sit in 1 to 5 ft that time of year. They don't go far with the seasons — 1 to 5 ft covers summer, 2 to 5 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 4 ft range, prime in winter. Fish it in after dark and the evening and you'll meet the bite.

Season	Depth	Best window	Start at
Spring	1 to 5 ft	dusk & night	Shallow bay flat (3 ft)
Summer	1 to 5 ft	night & dusk	Shallow bay flat (3 ft)
Fall	2 to 5 ft	dusk	Deep basin (4 ft)
Winter	2 to 5 ft	midday	Deep basin (4 ft)
