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 Margaret Lake: what the data says

238-acre lake in Timiskaming District, Ontario. The lake tops out around 5 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.

Traced from the shoreline, Margaret Lake runs 238 acres with 4 miles of edge. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 1.4 mi, about 0.6 mi across. You'll find it in Timiskaming District. The nearest mapped water is Benson Lake, 3 mi to the north.

Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
