Overview

Southern Alberta's rivers are experiencing rising flows due to onset spring runoff, with most running high and murky. This makes fishing conditions challenging, particularly on mountain rivers like the Sheep, Ghost, and Highwood. For better opportunities, focus on tailwaters and stocked ponds, which tend to remain clear and productive even during runoff.

River & Lake Conditions

• Sheep River: Currently at 26.1 m³/s, which is very high for this time of year, approaching the upper range of typical spring runoff. The river is rising and fishing will be difficult due to fast and discoloured water. Stick to clear banks and side channels.

• Ghost River: Flowing at 7.7 m³/s, significantly above its typical spring runoff high water. The river is rising and likely to be fast and discoloured. Consider fishing other less impacted waters like tailwaters or spring creeks.

• Highwood River: Currently at 19.3 m³/s, significantly above the norm, making it fast and discoloured. Rising water levels suggest challenging conditions. Tailwaters are a better bet.

• Bow River (near Banff, Cochrane, and Calgary): Flows are slightly elevated, reaching near or above seasonal spring runoff highs, with discoloured water expected. Focus on fishing with nymphs and streamers in back eddies and near structures.

• Oldman River (near Lethbridge): Flow at 75 m³/s suggests rising, fast, and somewhat murky conditions. Fish back eddies where walleye tend to concentrate.

Weather Impact by Area

Bow Valley / Foothills: Clear skies will dominate, but wind gusts up to 49 km/h will make fly fishing, particularly with small dries, challenging. Stick to nymphing and streamer patterns for better results.

Crowsnest Pass: Similar clear skies with gusty winds up to 48 km/h, making small dry flies difficult to present. Opt for sub-surface tactics with nymphs or heavier streamers.

Central Alberta: Warmer temperatures in the low 30s and dry conditions should encourage terrestrial activity, suggesting grasshoppers might be effective along banks, especially in the afternoon.

Hatch Activity & Fly Fishing

Strong midge hatches are expected across many streams — focus on small midge larvae and emerger patterns, using size 18-26 flies. Pre-hatch nymph fishing in the morning should be productive. Areas like the Highwood River offer a range of active hatches, from Yellow Sallies to Spotted Sedges. Use nymphing techniques early, and switch to dries like Grasshoppers and PMDs midday, but only if winds ease. With high and discoloured conditions, lean towards streamers like Woolly Buggers in olive or black, focusing on structure and deeper pools.

Spin & Bait Fishing

For conventional anglers, the challenging river conditions suggest targeting walleye and pike in back eddies on the Oldman River with jigs tipped with minnows or 3" Berkley Gulp Minnows. For stocked trout, PowerBait or small spinners can be effective in ponds. Use heavier, brighter inline spinners or spoons for more visibility in murky waters.

Recent Stocking

• Mount Lorette Ponds: Recently stocked with Rainbow and Westslope Cutthroat Trout — a great choice today given their recent stocking and likely clearer water conditions.
• Kids Can Catch Pond: Stocked with Rainbow Trout — ideal for family fishing adventures with good volume and accessible conditions, especially given moderate winds.

Top Picks Today

• Mount Lorette Ponds: Offers recently stocked Rainbow and Cutthroat Trout. Fly anglers use Elk Hair Caddis or Copper Johns; spin fish with small spinners.
• Bow River near Calgary: Fishing is marginal, but with rising flows, try heavy streamers or Clouser Minnows. Spin anglers can use larger spoons at seams and edges.
• Oldman River (Lethbridge back eddies): Target walleye with jigs in backwaters where flows provide refuge. Trout presentations improve when flows drop.

Safety & Regulations

Use extra caution due to high water levels affecting many southern rivers. Ensure catch-and-release regulations are adhered to for bull trout. Avoid disturbing spawning areas and fish paired on redds, particularly as runoff continues. It's essential to verify the current rules for specific bodies of water at albertaregulations.ca before heading out.
