Primary method with recommended setup and baits. Tap alternatives to expand.

Hare's Ear Nymph

#12–16 · Natural / Gold bead

Universal confidence fly. Fish it anywhere, always.

Pheasant Tail Nymph

#14–18 · Copper wire rib

Deadly in clearer water or when fish are selective.

Tungsten Bead Caddis

#12–16 · Olive / Brown

Heavy bead gets to the bottom fast in higher flows.

Stonefly Nymph

#8–12 · Black / Brown, heavy

Big meal for big fish. Fish along the bottom in fast runs.

Zebra Midge

#18–22 · Black/silver or red/silver

When nothing else works in low clear water.

Sulphur Nymph

#14–16 · Yellow / Olive

Pre-hatch nymphing — fish the last hour before hatch begins.

Woolly Bugger

#4–8 · Olive, Black, Brown

Grand River standard. Olive in normal conditions, black in stained.

Sculpin Pattern

#4–6 · Tan / Brown, weighted

Browns eat sculpins year-round. Dead-drift then strip erratically.

Clouser Minnow

#4–8 · Chartreuse/White or Olive/White

Excellent in slightly elevated or stained water.

Articulated Streamer

#2–4 · Natural or White, jointed

Big fly for trophy fish. Strip fast, pause — erratic triggers reaction strikes.

Elk Hair Caddis

#14–16 · Tan / Olive

Evening staple. Caddis hatches reliable May–September.

Parachute Adams

#14–18 · Grey

All-purpose dry when you see rises but can't ID the hatch.

Sulphur Comparadun

#14–16 · Yellow / Orange

Match the evening sulphur hatch May–July. Low-riding profile.

Royal Wulff

#12–14 · Classic attractor

High-floating. Also works as a dry-dropper indicator.

Classic crankbait for river browns. Perch in clear water, firetiger in stained.

Blue Fox Vibrax Spinner

#3–5 · Silver / Gold blade

Silver in clear conditions, gold in stained. Slow retrieve in cold.

Kastmaster Spoon

Gets deep fast. Work it through pools and current seams near structure.

Mepps Aglia Spinner

#3–4 · Black/Yellow, Natural

Classic trout spinner. Consistent in all flows through seams.

Roe Bag

Small mesh sacs · Natural or cured

The most effective float fishing bait in Ontario rivers. Match size to flow — smaller in low clear water, larger in high stained water.

Highly effective for steelhead and salmon. Peg 1–2 inches above hook. Pink in coloured water, natural/peach in clear.

Hard Bead

8–12 mm · Nuke Egg colours

Peg 1–2 inches above hook. Chartreuse and orange are top producers.

Plastic Worm

3–4 inch · Red, Pink, Chartreuse

Thread onto hook and drift naturally. Red and pink for stained water, natural for clear.

Nightcrawler

Classic bait for all trout species. Best in spring and after rain when naturals are washing in.

Bait rules vary by river — always verify current OMNR regulations before fishing.
