Rising on snow-swept glaciers east of Banff National Park, the Red Deer River carves 724 km of alpine canyons, foothill forest and moon-like badlands before slipping into Saskatchewan. Cold mountain water supports cutthroat and bull trout in the headwaters, while the big prairie reaches downstream of Sundre grow hefty brown trout, goldeye, pike and walleye. A chain of provincial recreation areas, county bridges and canoe launches make this diverse fishery reachable for day-trippers from Calgary, Red Deer and Edmonton.
**Upper Foothills (Banff boundary → Ya Ha Tinda Ranch):** pocket-water and plunge pools populated by native cutthroat. **Forestry Trunk Road Canyon (Ya Ha Tinda → Sundre):** swift freestone corridor famous for summer stonefly hatches and bull-trout ambushes. **Prairie Meanders (Sundre → Drumheller):** slower runs under cottonwoods with brown trout, goldeye and rising whitefish. **Badlands Reach (Drumheller → Bindloss/SK border):** braided sandbars and deep cut-banks holding trophy pike, walleye and prehistoric lake sturgeon.
Headwater riffles shelter westslope cutthroat to 35 cm and threatened bull trout exceeding 70 cm. Mid-river browns push 60 cm, joined by wild rainbows and mountain whitefish. Goldeye, northern pike and walleye dominate the lower reaches, and the river is Alberta’s only stronghold for endangered lake sturgeon.
April skwala stones spark surface eats in canyon pockets. June golden-stone and salmonfly hatches yield violent strikes on size-6 dries. PMDs, caddis and evening drake flights keep trout looking up through July, while prairie winds push hoppers and willow beetles onto grassy banks. Autumn browns devour olive sculpins before the spawn, and winter pods of whitefish sip #20 midges in gentle eddies near Drumheller.
A 9-ft 6-wt with floating line is the work-horse for stonefly and hopper fishing; pair a 7-wt sink-tip to swing 10 cm streamer patterns for bulls. Euro-nymphers favour 10-ft 4-wts and 3 mm tungsten Perdigons in high-gradient slots. In the badlands, spinning outfits with 15 lb braid and crankbaits tempt pike and walleye during spring runoff colour.
Ya Ha Tinda campground accesses deep emerald pools legendary for summer bull-trout chases. Forestry Trunk Road bridge 38 offers walk-in riffles perfect for golden-stone dries. The McKenzie Crossing launch near Sundre is a hotspot for brown-trout hopper action, while Midland Provincial Park in Drumheller provides easy bank casting for goldeye at dusk.
Highway 40 (K-Country) offers multiple gravel pull-outs to the upper river (closed to vehicles 1 Dec–14 Jun). Forestry Trunk Road (734) parallels 65 km of canyon water with rustic launches at bridge 38 and Burnt Timber Rec Area. Central reaches host maintained ramps at McKenzie, Tolman and Bleriot ferries; canoeists often float the 28 km badlands stretch between Drumheller and Morrin Bridge.
Flies/lures: #6 foam salmonfly, #10 hopper, #14 tan caddis, #16 PMD sparkle dun, #4 olive circus peanut, #2 chartreuse Clouser, ¾-oz silver crankbait. Leaders: 9 ft 4X for dries, 7.5 ft 0X for streamers, 10 ft 5X fluoro for nymphs. Studded rubber soles tackle algae-slick shale; felt is legal but all watercraft must stop at AIS check-points May–Oct.
Large-scale flooding (2013) reshaped channels and deposited fine sediment; Trout Unlimited Canada and Alberta Conservation Association anchor willow-plantings to stabilise banks. The lower river supports Alberta’s only self-sustaining lake-sturgeon run—anglers must release all sturgeon immediately. Mandatory Clean-Drain-Dry rules combat zebra-mussel threats; decontamination stations operate on Highways 2 and 9.
Spring snowmelt can triple flows overnight—consult gauges and avoid wading mid-channel after rain. Steep mud banks in the badlands crumble underfoot; exit cautiously. Rattlesnakes and ticks frequent sage slopes downstream of Drumheller—wear long pants and check nightly. Upper-canyon grizzly sightings are common; carry bear spray and make noise on blind bends.
**Cuttbow Fly Shop** (Okotoks) leads golden-stone float trips and stocks large streamer patterns. **Country Pleasures** (Calgary) hosts Euro-nymph clinics on Forestry Trunk Road runs. **West River Fly Shop** (Red Deer) sells walleye gear and arranges shuttle service for badlands canoeists. All issue Alberta licences and AIS decals.

The Red Deer River crosses ES2 and PP2 zones. **Upstream of Gleniffer Lake (ES2)**: catch-and-release for all trout; bait fish and barbed hooks prohibited; open season 16 June – 31 October. **Downstream of Gleniffer Dam (PP2)**: walleye limit one ≥ 50 cm, pike limit three (63–105 cm slot), barbless hooks mandatory; trout catch-and-release. Lake sturgeon, bull trout and burbot are closed to retention anywhere in the river. Anglers aged 16–64 require an Alberta Sportfishing Licence, and trailered boats must clear AIS inspections when stations are operating. Refer to the 2025 Alberta Guide to Sportfishing Regulations for detailed boundary maps and in-season changes.
