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 Terace L.: what the data says

159-acre lake in Algoma District, Ontario. The lake tops out around 30 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. The rest of this page walks each species through its year, using the map's own scoring.

On the chart, Terace L. draws 159 acres inside 4.7 miles of shoreline. That shoreline is heavily fingered (development index 2.7) — bays, points and pockets everywhere, which multiplies the fishable edge. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 1.1 mi, about 0.5 mi across. The water lies in Algoma District. The nearest mapped water is Sharon L., 2 mi to the southeast.

Yellow Perch fishing at Terace L.

Spring yellow perch on Terace L. hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 9 to 30 ft. The chart's best answer is Deep basin — deep basin, 28 ft, prime for fall. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	midday & dawn	Shallow bay flat (1 ft)	Small jig + curly tail, Perch-pattern micro crank
Summer	10 to 30 ft	dawn	Deep basin (28 ft)	Drop-shot micro plastics, Small spoon tipped with worm

Winter	9 to 30 ft	midday & dawn	Deep basin (28 ft)	Tungsten jig + spikes, Rattle spoon (small)

Burbot fishing at Terace L.

Start shallow in spring: burbot sit in 9 to 30 ft that time of year. They don't go far with the seasons — 9 to 30 ft covers summer, 8 to 30 ft covers winter. The spot to know is Deep basin, a deep basin in about 28 ft of water that rates prime for burbot in spring. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	9 to 30 ft	night & dusk	Deep basin (28 ft)	Glow jigging spoon + cut bait, Rattle bait (dark)
Summer	9 to 30 ft	night & midday	Deep basin (28 ft)	Heavy jig + cut bait
