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 Gleason Lake: what the data says

52-acre lake in Grey County, Ontario. The lake tops out around 5 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. What follows comes from the same scoring engine that paints the spots above.

Traced from the shoreline, Gleason Lake runs 53 acres with 1.7 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.5 mi with a 0.3-mi widest point. You'll find it in Grey County. The nearest mapped water is Lake Charles, 1 mi to the south.

Yellow Perch fishing at Gleason Lake

When the water first warms, yellow perch slide up into 1 to 5 ft. There's no big seasonal slide here — summer means 2 to 5 ft, winter 2 to 5 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
