Overview

Anglers focusing on Southern Alberta this Friday will find a mix of conditions. Spring runoff is generally normal, though some rivers are running low. The Bow River around Calgary offers consistent trout opportunities with manageable flows. Expect caddis and BWO hatches in some areas, while trout stocking enhances pond fishing options.

River & Lake Conditions

• Bow River (Upper / Banff): Flow is steady at 58.9 m³/s. This is a good time for those comfortable wading or floating, as the flow is well within fishable limits. Trout are likely holding in deeper runs and pools.

• Bow River (Calgary Blue Ribbon): With a flow of 133 m³/s, wading is difficult, but floating is viable. Trout will be found in slower water near banks and structure.

• Bow River (Lower): Flows at 119 m³/s are prime for targeting walleye in back eddies and structure. Trout will be closer to shorelines.

• Crowsnest River: Currently at 9.1 m³/s, the Crowsnest offers productive fishing with manageable flows for wading. Trout are active, particularly around riffles and pocket waters.

• Oldman River (Below Dam): At 50.0 m³/s, flows are ideal for both wading and fishing from shore. Cold water ensures trout are active year-round here.

Weather Impact by Area

• Bow Valley / Foothills: Expect overcast skies, temperatures ranging 6–18°C, and gusty winds up to 43 km/h in the afternoon. Small dry fly presentations will be challenged; nymphing and streamer fishing are advisable.

• Crowsnest Pass: Overcast conditions with highs around 17°C and wind gusts up to 33 km/h. Afternoon winds could complicate dry fly fishing; stick to nymphs or streamers.

• Central Alberta: Weather is partly cloudy with mild winds and temperatures from 5–22°C. Generally favorable for fishing, tracking afternoon gusts will remain crucial for fly angling on open waters.

Hatch Activity & Fly Fishing

• Bow River (Calgary): Moderate Grannom caddis (hooks #14–16) and high BWO hatches (hooks #18–22). Pre-hatch nymphing is effective—try Hare's Ear and Pheasant Tail nymphs. Streamers such as Woolly Buggers work well in the deeper pools.

• Crowsnest River: Heavy Grannom caddis and peak BWO action. Use BWO emergers and adults (#18–20) for surface action. Nymphing with Copper Johns under an indicator is reliable. Streamers may also be productive in deeper runs.

Spin & Bait Fishing

• Bow River (Calgary): Spin anglers can effectively use Blue Fox Vibrax (#2-3) and Rapalas along bank edges and structure.

• Oldman River (Below Dam): Small spinners and jigs tipped with soft plastics will appeal to both trout and walleye near back eddies.

• Stocked Ponds: Freshly stocked ponds are ideal for using PowerBait or worms near inlets.

Recent Stocking

Recent stockings at Allison Lake, Sibbald Lake, and other local ponds are noteworthy. Stocked ponds are perfect for simple setups—PowerBait and small inline spinners will attract attention among recently introduced trout.

Top Picks Today

• Bow River (Calgary): Flows are conducive to floating. Use Hare's Ear nymphs under an indicator or Blue Fox spinners.

• Oldman River (Below Dam): Steady flows support all-day fishing. Go with Clouser Minnows for fly or small jigs paired with soft plastics for spin anglers.

• Crowsnest River: Manageable flows mean good action on dry flies and nymphs. Consider BWOs or Copper Johns, while small Mepps spinners should work well for spin anglers.

Safety & Regulations

• Exercise caution wading all rivers this weekend, especially with fluctuating flows and slick, muddy banks.
• Bull Trout remain catch-and-release only across Alberta.
• The Sheep River is low—fish cautiously and verify any upper river closures for cutthroat protection.
• Seasons and closures vary by water body and species — always verify at albertaregulations.ca before fishing.
