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 Simms Lake: what the data says

39-acre lake in Parry Sound District, Ontario. The lake tops out around 88 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What the data behind the map says about each species, season by season:

Drawn out, this is 39 acres of water rimmed by 1.7 miles of bank. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. Roughly 8% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.5 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Parry Sound District. The nearest mapped water is Little Etta Lake, 2 mi to the northwest.

Yellow Perch fishing at Simms Lake

Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 6 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	midday & dawn	Shallow bay flat (6 ft)	Small jig + curly tail, Perch-pattern micro crank
Summer	10 to 30 ft	dawn	Shallow bay flat (6 ft)	Drop-shot micro plastics, Small spoon tipped with worm
Fall	12 to 35 ft	midday	Break off the point (40 ft)	Jigging spoon (small), Perch rig / spreader
Winter	15 to 35 ft	midday & dawn	Deep basin (75 ft)	Tungsten jig + spikes, Rattle spoon (small)

Smallmouth Bass fishing at Simms Lake

Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 20 to 45 ft. Top water on the chart: Main-lake point, a point in the 22 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	dawn & dusk	open water	Ned rig, Tube jig
Summer	10 to 30 ft	dawn & dusk	Main-lake point (22 ft)	Drop shot (goby/minnow), Ned rig
Fall	8 to 25 ft	midday & dawn	Main-lake point (22 ft)	Jerkbait, Blade bait
Winter	20 to 45 ft	midday	Break off the point (40 ft)	Blade bait, Hair jig

Pumpkinseed fishing at Simms Lake

Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. The chart's best answer is Shallow bay flat — feeding flat, 6 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 8 ft	midday & dusk	Shallow bay flat (6 ft)	Micro jig under a float, Tiny beetle-spin
Summer	2 to 10 ft	dusk & dawn	Shallow bay flat (6 ft)	Micro tube, Sponge spider (fly)
Fall	4 to 14 ft	dusk & dawn	Shallow bay flat (6 ft)	Micro jig + waxworm, Small spoon tipped
Winter	6 to 18 ft	dawn	Shallow bay flat (6 ft)	Tungsten ice jig + plastic, Tiny spoon
