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 Fleming Lake: what the data says

33-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 39 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Species by species, here's what the data says the year looks like.

Drawn out, this is 32 acres of water rimmed by 1.1 miles of bank. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 31% of this chart, as modeled. Figure 0.4 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Muskoka District Municipality. For a second option, Lena Lake lies 1 mi north.

Smallmouth Bass fishing at Fleming 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 12 to 39 ft. Main-lake point is the standout, a point at roughly 10 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 (10 ft)	Ned rig, Tube jig
Summer	10 to 30 ft	dawn & dusk	Break off the point (18 ft)	Drop shot (goby/minnow), Ned rig
Fall	8 to 25 ft	midday & dawn	Main-lake point (10 ft)	Jerkbait, Blade bait
Winter	12 to 39 ft	midday	Break off the point (18 ft)	Blade bait, Hair jig

Pumpkinseed fishing at Fleming 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. Start at Shallow bay flat. It's a weed flat holding about 5 ft of water and rates prime come spring. 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	Shallow bay flat (5 ft)	Micro jig under a float, Tiny beetle-spin
Summer	2 to 10 ft	dusk & dawn	Shallow bay flat (5 ft)	Micro tube, Sponge spider (fly)
Fall	4 to 14 ft	dusk & dawn	Shallow bay flat (5 ft)	Micro jig + waxworm, Small spoon tipped
Winter	6 to 18 ft	dawn	Shallow bay flat (5 ft)	Tungsten ice jig + plastic, Tiny spoon

Brown Bullhead fishing at Fleming Lake

Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 10 to 25 ft. The spot to know is Shallow bay flat, a weed flat in about 5 ft of water that rates prime for brown bullhead in spring. Warm-month bites cluster around after dark and the evening.

Season	Depth	Best window	Start at
Spring	2 to 8 ft	dusk & night	Shallow bay flat (5 ft)
Summer	3 to 12 ft	night & dusk	Shallow bay flat (5 ft)
Fall	5 to 15 ft	dusk	Shallow bay flat (5 ft)
Winter	10 to 25 ft	midday	Deep basin (33 ft)
