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 Back Lawrence L.: what the data says

1,105-acre lake in Kenora District, Ontario. The lake tops out around 158 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. The season-by-season read for each species follows, from the map's own numbers.

Back Lawrence L. maps at 1,112 acres behind 27.3 miles of shoreline, with 4 islands in the mix. A development index of 5.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 24% of the surface on the model — that's where the groceries are. Call it 3.4 mi long by 2.6 mi wide at the broadest reach. Kenora District claims this one. If the bite dies, Hector Lake is 2 mi to the northwest.

Lake Trout fishing at Back Lawrence L.

Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. The chart's best answer is Main-lake point — point, 40 ft, prime for spring. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 40 ft	dawn & dusk	Main-lake point (40 ft)	Casting spoon over shoals, Jerkbait (shallow)
Summer	50 to 120 ft	dawn	Break off the point (71 ft)	White tube jig (deep), Magnum spoon on downrigger
Fall	10 to 50 ft	dusk & dawn	Main-lake point (40 ft)	Heavy casting spoon, Jigging rap over reefs
Winter	20 to 80 ft	dawn	Break off the point (71 ft)	White tube jig, Airplane jig

Lake Whitefish fishing at Back Lawrence L.

Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. Warm water sends them out to 40 to 90 ft; cold water stacks them in 25 to 70 ft. Break off the point is the standout, a drop-off at roughly 71 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	15 to 45 ft	midday & dawn	open water	Small jig + waxworm, Blade bait (small)
Summer	40 to 90 ft	dawn	Break off the point (71 ft)	Blade bait vertical, Small jigging spoon
Fall	8 to 30 ft	dusk	open water	Small spoon (gold), Jig + plastic larva
Winter	25 to 70 ft	midday & dawn	Break off the point (71 ft)	Jigging spoon + bead chain, Tungsten jig + waxie

Cisco (Lake Herring) fishing at Back Lawrence L.

Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 40 to 80 ft; cold water stacks them in 20 to 60 ft. Break off the point is the standout, a drop-off at roughly 71 ft, rated good for summer cisco (lake herring). Plan around early morning in the warm months. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 40 ft	dawn & dusk	open water	Small silver spoon, Tiny swim jig (white)

Walleye fishing at Back Lawrence L.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. The spot to know is Main-lake point, a point in about 40 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	4 to 15 ft	dusk & dawn	open water	1/8 oz jig + minnow, Hair jig
Summer	15 to 35 ft	dusk & dawn	Main-lake point (40 ft)	Crawler harness on bottom bouncer, Deep crankbait (trolled)

Yellow Perch fishing at Back Lawrence L.

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
