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 Cabot L. 3: what the data says

21-acre lake in Sudbury District, Ontario. The lake tops out around 20 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here is how the season plays out for each species, straight from the data behind the map.

The outline encloses 21 acres, worked by 0.9 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 75% of the surface on the model — that's where the groceries are. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. It sits in Sudbury District. Its nearest charted neighbour, Ketchiwaboose Lake, is 0 mi to the west.

Yellow Perch fishing at Cabot L. 3

Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
