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 Seven Lake: what the data says

15-acre lake in Parry Sound District, Ontario. The lake tops out around 21 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. What the data behind the map says about each species, season by season:

On the chart, Seven Lake draws 15 acres inside 1.1 miles of shoreline. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. Roughly 84% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 0.4 mi, about 0.2 mi across. You'll find it in Parry Sound District.

Yellow Perch fishing at Seven Lake

Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 6 to 21 ft in summer and finish the year down in 6 to 21 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 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	6 to 21 ft	dawn	Deep basin (18 ft)	Drop-shot micro plastics, Small spoon tipped with worm
Fall	6 to 21 ft	midday	Deep basin (18 ft)	Jigging spoon (small), Perch rig / spreader
Winter	6 to 21 ft	midday & dawn	Deep basin (18 ft)	Tungsten jig + spikes, Rattle spoon (small)
