Overview

Today's conditions in Southern Alberta are generally promising for anglers, with flows near summer levels across many rivers, though some are experiencing slight rises. With hatches active, particularly midges and grasshoppers, there are great opportunities for fly fishing enthusiasts. Anglers should be aware of wind conditions, especially in afternoon, which may affect casting accuracy.

River & Lake Conditions

• Sheep River near Okotoks: Flow is 5.0 m³/s, steadily rising, yet near typical summer levels. Expect typical summer conditions suitable for trout fishing. Best targeting bank edges due to solid spotted sedge activity this evening.
• Ghost River: Flow at 5.8 m³/s is stable and slightly above typical spring high water, providing good fishing levels. Expect bank structures to hold fish with grasshopper activity high today.
• Crowsnest River: Flow at 3.2 m³/s is receding, promising optimal conditions for nymphing. Focus on riffles and pools for active brown trout and cutthroat.
• Bow River near Cochrane: Rising flow at 96.2 m³/s, excellent for streamer fishing along seams and deeper runs as leapfrogging glacial melt pushes fish to structure.

Weather Impact by Area

• Bow Valley / Foothills: Winds gusting to 71 km/h impact dry fly presentations, but afternoon streamers or nymphs will perform well. Expect clear skies and moderate temperatures up to 26°C.
• Crowsnest Pass: Overcast shifts to clear by evening, with gusts up to 58 km/h. Streamer retrievals in cut bank pools could engage lurking bulls and browns.
• Central Alberta: Warm temperatures and manageable west winds suggest productive lake fishing; casting preferences should adapt to wind direction for optimal angles.

Hatch Activity & Fly Fishing

• Sheep River: Midge (#18-26) and Spotted Sedge (#14-18) hatches provide excellent targets for small dry fly skitters in runs. For nymphing, consider using lighter 4X tippets with a #18 Pheasant Tail, aiming deep pools.
• Ghost River: Grasshoppers (#8-12) are the main draw; target bank undercuts with dry droppers. Anchor with a #16 Copper John nymph underneath for effective results.
• Highwood River: Strong Trico (#20-24) activity; morning spinner falls make for superb dry fly opportunities with elk hair caddis recommended as the afternoon shifts.

Spin & Bait Fishing

• In the Sheep River, Blue Fox Vibrax #2 or Mepps Aglia #2 tipped with nightcrawler chunks is ideal for enticing rainbow and brown trout hiding along seams.
• Oldman River near Lethbridge: Try chartreuse Gulp Minnow on a 1/8 oz jig for steady walleye action in eddies. Prevent excess line slack to ensure hook sets in slightly rising conditions.
• Lakes: PowerBait or worm setups at Mclean Pond will yield results for recently stocked trout with angling near depth transitions for wider coverage.

Recent Stocking

• Mclean Pond: 2,300 Westslope Cutthroat stocked. Fish along shorelines shielded from wind for success.
• Sibbald Lake: Freshly stocked with 1,000 Rainbow Trout. Target areas with leeside protection from afternoon gusts.
• Mount Lorette Ponds: Offers dual opportunities with rainbow and cutthroat trout, adjust drifts for rainbows favoring surface insects.

Top Picks Today

1. Sheep River near Okotoks: Flows steady, optimal nymph action with #18 Hare's Ear beneath hoppers. Spin anglers use Vibrax #2 near higher flow banks.

2. Ghost River: Active dry fly action with grasshoppers along banks. Use light spinning gear with small Mepps spinners for cutthroat.
