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 Maunsell Lake: what the data says

14-acre lake in Renfrew County, Ontario. The lake tops out around 7 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. Below is the species-by-species picture, pulled from the same data the map uses.

Drawn out, this is 13 acres of water rimmed by 1.3 miles of bank. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. 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 0.6 mi of water from one end to the other. The water lies in Renfrew County. Closest neighbour on DepthScout: Thomas Lake, 1 mi southeast of here.
