Overview

Today's focus is navigating the effects of spring runoff, which is intensifying across Southern Alberta. Most mainstem rivers are experiencing rising, discoloured conditions that will limit fishing success in many regions. For those seeking the best opportunities, consider fishing tailwaters, spring creeks, or recently stocked ponds during this period.

River & Lake Conditions

• Sheep River near Okotoks: Flows have surged to 19.5 m³/s, significantly above the summer median. With the onset of freshet, expect discoloured water and use caution. Bank edges and back eddies are your best bets.
• Ghost River: Currently at 4.0 m³/s and receding. As flows drop and clarity improves, focus on riffles and runs for cutthroat and whitefish.
• Highwood River near High River: Now flowing at 57.9 m³/s, a clear sign that freshet is underway. Fish the calmer waters of tailwaters or spring creeks.
• Oldman River near Lethbridge: Flowing at 109.0 m³/s but receding. While walleye thrive in such conditions, wait for clarity to improve for effective trout fishing.
• Crowsnest River: At 16.1 m³/s and rising, expect very challenging conditions. Bank fishing and side channels are recommended until flows recede.

Weather Impact by Area

• Bow Valley / Foothills: Temperatures will range from 15–28°C, with wind gusts peaking at 30 km/h in the afternoon. This makes presenting small dry flies near impossible; opt for nymph fishing using larger patterns or switch to streamers when the gusts are strongest.
• Crowsnest Pass: With gusts up to 43 km/h this afternoon, prioritize fishing deep and cold pools using streamers. Air temperatures will hover between 13 and 24°C.
• Southern Alberta Plains: Including the Oldman and Milk Rivers, anticipate moderate drizzle through Lethbridge with winds up to 42 km/h later. Focus on sheltered back eddies for pike and walleye using brightly colored lures.

Hatch Activity & Fly Fishing

• Sheep River: Blue-winged Olive (Baetis) hatch is active. Start with Baetis nymphs (size 18-22) throughout the day, and dry fly fish in the afternoon when the wind calms down. Use a double nymph rig with an indicator; small streamers also work well in murky conditions.
• Ghost River: Midges and Grannom caddis are prominent. For nymphing, a size 18 midge larva works well. Expect some surface action in calmer sections on overcast afternoons.
• Crowsnest River: Grannom and Blue-winged Olive present. Use nymphs early, transitioning to a dry fly setup if a hatch becomes evident when wind conditions permit.

Spin & Bait Fishing

• Walleye & Northern Pike: In the Oldman River, use 3/8 oz. chartreuse jig heads with minnows or bright crankbaits. Pike may respond well to large spoons and spinnerbaits in back eddies.
• Stocked Trout Ponds: PowerBait or worms on light tackle will be effective, especially in lakes recently stocked with rainbows or cutthroat. Adjust your position according to wind direction for optimal casting angles.

Recent Stocking

• Little Beaverdam Lake: Recently stocked with 1,000 tiger trout. Good access and stable conditions make it an excellent choice for catching trout using PowerBait or small spoons.
• Sibbald Meadows Pond: Stocked on May 14 with 2,000 rainbow trout. It's sheltered from the wind, making it ideal for light tackle and bait fishing.
• Mount Lorette Ponds: Offers both rainbow and cutthroat trout stocked earlier this month. Explore these ponds while using light spinners and flies on slow retrieves.

Top Picks Today

• Sibbald Meadows Pond: Excellent for stocked rainbows. Use PowerBait or small Mepps spinners.
• Oldman River near Lethbridge: Walleye in eddies, targeting with chartreuse jigs and minnows.
• Ghost River: Focus on nymphing with high-probability hatches of Blue-winged Olives and Grannom caddis.

Safety & Regulations

• Be aware of high water levels and use caution near all rivers as they are running above normal.
• Bull trout must be released if caught and handle with care.
• Avoid wading through identified spawning grounds for various species and do not target fish on redds.
• Seasons and closures vary by water body and species — always verify at albertaregulations.ca before fishing.
