Westfall River

Confirm the current Region 4 table before fishing. Westfall is handled here as Duncan Lake / Upper Duncan tributary context with bull trout release; no individual Westfall River exception was found in this pass .

Key points

• Identity: NRCan lists Westfall River as an official Kootenay Land District river at 50.781111, -117.197778 .
• Fish signal: the local named-line extraction found six direct records, all Bull Trout .
• Bull trout role: ONA says Westfall was selected as the best repeated bull trout redd survey site for Duncan Reservoir monitoring, with roughly 30 percent of bull trout estimated to use Westfall in that study context .
• Water character: BC Hydro describes Westfall as a fifth-order river flowing about 29 km east to the Upper Duncan, with a steep lower bedrock canyon, high-elevation upper watershed and less glacial input than other Upper Duncan tributaries .
• Access: monitoring reports mention Westfall FSR along much of the river, but upper-watershed access was reduced after partial deactivation to lower traffic and protect caribou habitat .
• Food: bull trout imply small fish, juvenile trout/char, Kokanee and Sculpin where connected; small Mayflies, Caddisflies (Sedges), Stoneflies and Terrestrials (Hoppers, Ants, Beetles) cover the lighter trout-food layer. for direct hatch data.
• Best flies: if legal and away from spawning fish, use small/medium sculpin or kokanee-fry streamers, Woolly Bugger, Prince Nymph, Gold-Ribbed Hare's Ear Nymph, Pheasant Tail Nymph, Elk Hair Caddis, Stimulator, Adams and Royal Wulff.
• Guides: no Westfall River-specific fishing-guide coverage found.

Health & stewardship

• Redd survey water: do not fish visible redds, staging bull trout or low/warm conditions. Treat every field plan as conservation-first.
• Kootenay connection: DDMMON-5 ties Upper Duncan bull trout, including Westfall-origin fish, to repeated migrations between the Duncan system and Kootenay Lake.

Open questions

• Confirm current road/FSR access, deactivation status, caribou closures, fishable reaches and whether any non-spawning-season fly opportunity exists without adding pressure to bull trout.
