Overview

Spring runoff is in full effect across southern Alberta, with many rivers experiencing rising flows and some discolouration. Tailwaters and recently stocked ponds are your best bets for consistent fishing. Always verify current conditions and regulations before heading out.

River & Lake Conditions

• Sheep River near Okotoks: Flows are currently rising, sitting at 11.0 m³/s, which is low but increasing (~29% recently). High water pushes trout to bank edges; look for fish in side channels.

• Ghost River: Flow is 1.9 m³/s and falling, suggesting clearing conditions. Runoff is receding, making it a potential target for both cutthroat and bull trout.

• Highwood River near High River: Holding steady at 29.4 m³/s, within normal range but still high due to runoff. Focus on deep pools and seams for bull trout.

• Oldman River near Lethbridge: Falling sharply to 36.8 m³/s; a great window for targeting trout and walleye as the river clears from recent freshet.

• Castle River: Rising flows at 47.2 m³/s indicate recent freshet or storm pulse — expect murky conditions. Consider tailwaters or spring creeks for better clarity.

Weather Impact by Area

Bow Valley / Foothills

• Expect gusty winds, up to 28 km/h N, in the Bow Valley today. This makes dry fly fishing challenging—opt for nymphing or streamers on the Bow River. Rain (up to 3.6 mm) affects clarity, especially with upstream glacial influences.

Crowsnest Pass / Oldman River

• Clear skies in the Oldman River area, with highs reaching 32°C. Winds 24 km/h ENE in Lethbridge could impact casting precision. The river is clearing, providing good fishing conditions.

Central Alberta

• Overcast with moderate winds (up to 25 km/h SW) on the Highwood and Sheep rivers. The cloudy weather suits BWO and midge hatches; nymphs will be productive.

Hatch Activity & Fly Fishing

Sheep River near Okotoks

• Nymph Fishing: Focus on small midge larvae (#18-24) and Baetis nymphs (#18-22) during morning hours. Use indicators for deep pools.
• Dry Fly Fishing: With BWO and Grannom activity, dry fly setups in the afternoon are promising if wind allows. Try Parachute Adams or Elk Hair Caddis in calm pockets.
• Streamers: Given the rising flows, olive Woolly Buggers (#6-10) will attract larger browns, particularly early morning or dusk.

Ghost River

• Nymph Fishing: Target mid-column with Pheasant Tail nymphs (#14-18). Falling flows improve visibility.
• Dry Fly Fishing: Consider surface patterns like Blue-winged Olives in the afternoon when fish are likely rising.
• Streamers: In deeper runs, Bunny Leeches (#2-4) can entice bull trout.

Spin & Bait Fishing

Trout and Whitefish Rivers

• Use Mepps Aglia spinners (#1-3) in clearer sections like the Ghost River. For Browns, small Rapalas are effective in eddies.

Lakes and Stocked Ponds

• Lakes are warming; focus efforts on stocked ponds with PowerBait or worms. Expect success with aggressive rainbows using 4-8 lb fluorocarbon line for stealth.

Walleye and Pike

• For walleye in the Oldman River, be sure to have a 1/8 oz jig and minnow handy. As flows drop, target back eddies and structure.

Recent Stocking

• Little Beaverdam Lake: Recently stocked with 1,000 Tiger Trout, prime for fly and spin anglers.
• Sibbald Meadows Pond: Stocked with rainbow trout, offering prime conditions for family outings.
• Kids Can Catch Pond: Recently stocked with rainbow trout, perfect for young anglers — try PowerBait or small spinners.

Safety & Regulations

• Use caution with high flows on the Castle River and Sheep River. Remember bull trout are catch-and-release only throughout Alberta.
• Current trout spawning season underway — observe ethical practices by avoiding redds and leaving paired fish undisturbed.
