Hatch outlook

Hopper & ant season (windward banks)Active window

Typical here: Jul 1 – Sep 15 · hoppers peak July–August; winged-ant falls show up on warm humid afternoons — a wind event, not a hatch

adultwarm, breezy afternoons, roughly 1–5pm — slap the imitation down hard — the splat is the trigger — then wait; count to three after the rise before setting

Work the windward bank on breezy summer afternoons — that's where the food is. Casting-bubble-and-hopper is the direct translation; otherwise run small topwaters and inline spinners tight along the grass edges and blowdown banks in the afternoon warmth.

The event happens over windward grassy banks, overhanging brush and blowdowns — wherever the breeze dumps the bugs

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 Loney Lake: what the data says

47-acre lake in Sudbury District, Ontario. The lake tops out around 62 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.

Drawn out, this is 47 acres of water rimmed by 2.2 miles of bank, with a single island in the mix. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 49% of this chart, as modeled. The basin spans about 0.7 mi end to end and 0.3 mi across at its widest. The water lies in Sudbury District. The nearest mapped water is Irish Lake, 2 mi to the west.

Lake Trout fishing at Loney Lake

The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 19 to 62 ft, wintering in 16 to 62 ft. Top water on the chart: Deep basin, a deep basin in the 53 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 40 ft	dawn & dusk	Main-lake point (16 ft)	Casting spoon over shoals, Jerkbait (shallow)
Summer	19 to 62 ft	dawn	Deep basin (53 ft)	White tube jig (deep), Magnum spoon on downrigger
Fall	10 to 50 ft	dusk & dawn	Main-lake point (16 ft)	Heavy casting spoon, Jigging rap over reefs
Winter	16 to 62 ft	dawn	Deep basin (53 ft)	White tube jig, Airplane jig

Yellow Perch fishing at Loney Lake

Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Break off the point first on the milk run — a drop-off near 28 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	midday & dawn	open water	Small jig + curly tail, Perch-pattern micro crank
Summer	10 to 30 ft	dawn	Break off the point (28 ft)	Drop-shot micro plastics, Small spoon tipped with worm
Fall	12 to 35 ft	midday	Break off the point (28 ft)	Jigging spoon (small), Perch rig / spreader
Winter	15 to 35 ft	midday & dawn	Break off the point (28 ft)	Tungsten jig + spikes, Rattle spoon (small)

Smallmouth Bass fishing at Loney Lake

In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 20 to 45 ft. Main-lake point is the standout, a point at roughly 16 ft, rated prime for fall smallmouth bass. Time it for early morning and the evening. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	dawn & dusk	Main-lake point (16 ft)	Ned rig, Tube jig
Summer	10 to 30 ft	dawn & dusk	Break off the point (28 ft)	Drop shot (goby/minnow), Ned rig
Fall	8 to 25 ft	midday & dawn	Main-lake point (16 ft)	Jerkbait, Blade bait
Winter	20 to 45 ft	midday	Break off the point (28 ft)	Blade bait, Hair jig

Rock Bass fishing at Loney Lake

Come spring, look for rock bass tight to the bank in 2 to 10 ft. Expect a summer slide to 5 to 20 ft, then a winter hold in 12 to 30 ft. Start at Main-lake point. It's a point holding about 16 ft of water and rates prime come summer. Prime time lands in the evening. A ned rig (small) or a marabou jig is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 10 ft	midday & dawn	open water	1/16 oz jig + grub, Small inline spinner
Summer	5 to 20 ft	dusk	Main-lake point (16 ft)	Ned rig (small), Marabou jig
Fall	8 to 22 ft	midday	Main-lake point (16 ft)	Small tube jig, Inline spinner
Winter	12 to 30 ft	midday	Break off the point (28 ft)	Tungsten jig + plastic, Small spoon + spike

Pumpkinseed fishing at Loney Lake

Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 6 to 18 ft. Prime time lands in the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 8 ft	midday & dusk	open water	Micro jig under a float, Tiny beetle-spin
Summer	2 to 10 ft	dusk & dawn	open water	Micro tube, Sponge spider (fly)
