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 Mulven Lake: what the data says

193-acre lake in Timiskaming District, Ontario. The lake tops out around 14 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here's the year, species by species, as the scoring engine sees it.

Drawn out, this is 191 acres of water rimmed by 3.6 miles of bank. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 1.3 mi of water from one end to the other, 0.5 mi at the beam. The water lies in Timiskaming District. Closest neighbour on DepthScout: Wawagoshe Lake, 2 mi southeast of here.

Walleye fishing at Mulven Lake

Come spring, look for walleye tight to the bank in 4 to 14 ft. Through summer count on 4 to 14 ft; the winter hold is 4 to 14 ft. If you only fish one area, make it Break off the point: a drop-off around 6 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	4 to 14 ft	dusk & dawn	Main-lake point (8 ft)	1/8 oz jig + minnow, Hair jig
Summer	4 to 14 ft	dusk & dawn	Break off the point (6 ft)	Crawler harness on bottom bouncer, Deep crankbait (trolled)
Fall	4 to 14 ft	dusk & night	Break off the point (6 ft)	Jigging rap, Jig + big minnow
Winter	4 to 14 ft	dusk & dawn	Deep basin (12 ft)	Jigging spoon + minnow head, Rattle bait

Yellow Perch fishing at Mulven Lake

Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 4 to 14 ft, then a winter hold in 4 to 14 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	midday & dawn	Shallow bay flat (3 ft)	Small jig + curly tail, Perch-pattern micro crank
Summer	4 to 14 ft	dawn	Deep basin (12 ft)	Drop-shot micro plastics, Small spoon tipped with worm

Winter	4 to 14 ft	midday & dawn	Deep basin (12 ft)	Tungsten jig + spikes, Rattle spoon (small)

Northern Pike fishing at Mulven Lake

Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 4 to 14 ft, and winter fish settle into 4 to 14 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 8 ft	midday & dawn	Shallow bay flat (3 ft)	#5 inline spinner, Spoon (red/white)
Summer	4 to 14 ft	dawn & dusk	Shallow bay flat (3 ft)	Bucktail, Weedless spoon over cabbage
Fall	4 to 14 ft	midday & dawn	Break off the point (6 ft)	Big rubber (Bull Dawg style), Husky-style jerkbait
Winter	4 to 14 ft	midday	Shallow bay flat (3 ft)	Tip-ups, Large jigging spoon

Rock Bass fishing at Mulven Lake

Early season rock bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 4 to 14 ft, then a winter hold in 4 to 14 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for summer. In summer the feeding windows fall in the evening. Tie on a ned rig (small) or a marabou jig and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 10 ft	midday & dawn	Main-lake point (8 ft)	1/16 oz jig + grub, Small inline spinner
Summer	4 to 14 ft	dusk	Main-lake point (8 ft)	Ned rig (small), Marabou jig
