Overview

Spring runoff is still affecting many rivers across southern Alberta, with high water levels and discolored conditions persisting in several areas. Anglers will find better opportunities in tailwaters and spring creeks, which are more stable, and at recently stocked ponds. Always check individual river conditions and regulations before heading out, as high streamflow advisories are in effect.

River & Lake Conditions

• Sheep River near Okotoks: Running at 30.2 m³/s, which is exceptionally high and challenging. Expect discolored water, and focus on back eddies and side channels for any chance of success.
• Bow River at Calgary: Flows at 230 m³/s, significantly high, with spring runoff ongoing. Target deeper runs and alongside structure; expect murky conditions.
• Crowsnest River: Flows at 9.4 m³/s, which is above average but receding. The river is clearing gradually, making it more fishable in the coming days. Stick to side channels and use heavier nymphs or streamers.
• Oldman River near Fort Macleod: No live flow data, but local conditions usually dictate heavy flows this time of year. Consult live gauges when planning a trip.

Flow caution: Most rivers are experiencing higher-than-normal flows — proceed with caution. Tailwaters like the Oldman below the dam offer more stable conditions.

Weather Impact by Area

• Bow Valley / Foothills: Wind gusts up to 31 km/h this afternoon, making small dry fly presentations difficult. Go for nymphs or streamers in the Bow Valley where possible. Higher temperatures might also increase activity later in the day.
• Crowsnest Pass: Moderate overcast with gusts around 37 km/h, best to avoid small dries and focus on streamers. Rivers may be clearing, leading to improved conditions by the weekend.
• Central Alberta: Partly cloudy with calm winds making conditions favorable. Consider exploring local ponds and dams which are clear of runoff effects.

Hatch Activity & Fly Fishing

• Crowsnest River: Midge hatches are predominant, favoring nymph setups with Chironomidae patterns (#18-26). Salmonfly and Green Sedge hatches are present; try large nymphs pre-hatch for best success. Evening caddis and grasshoppers will start showing up — have stimulators and hoppers ready.

• Highwood River: Expect Pale Morning Duns and Green Sedges — nymphs (Pheasant Tail #16-18) work well in riffles before the hatch starts in the morning. Evening may bring out caddis action.

• Streamers: With murkier waters, use heavier, brighter patterns like Woolly Buggers in olive or black, especially in deeper or faster runs.

Spin & Bait Fishing

• Bow River: Spin with Rapala F5 or Mepps spinners in brighter colors due to discolored conditions. Work lures across seams and structure.
• Crowsnest River: Utilize small inline spinners in side channels, focusing on slower pools.
• Stocked Ponds: Go for PowerBait and small spinners where water levels are stable.

Recent Stocking

• Mount Lorette Ponds: Recently stocked with rainbow and cutthroat trout. Given today's moderate weather and stable conditions, a prime location for family fishing with bait setups.
• Kids Can Catch Pond: Rainbow trout stocked; calm weather makes for pleasant conditions. Try floating PowerBait and worms.

2. Mount Lorette Ponds: Freshly stocked with trout, offering a reliable and enjoyable outing. Fly fish with Royal Wulff or use PowerBait for spin anglers.

Safety & Regulations

• High Water Caution: Exercise great care around all high-flowing rivers. Avoid wading and focus on shore fishing if flows are high.
• Bull Trout: Catch-and-release only in all waters — handle fish carefully.
• Spawning Seasons: Avoid disturbing any spawning gravels, particularly relevant for trout in mountainous streams.
