No individual Houston Creek listing appears in the current Region 4 synopsis. On paper it sits inside the Duncan Lake tributaries bucket (4-27): bull trout catch-and-release across the Upper Duncan River and its tributaries, plus the regional stream defaults, no fishing Apr 1 to June 14, single barbless hook year-round, winter release Nov 1 to Mar 31. Confirm the current synopsis, or call the Region 4 office, before fishing it.

NRCan's official Kootenay Land District listing places Houston Creek at 50.986111, -117.232222. The local waterway index records it as an 18 km, fourth-order stream (mid-range in the network, on a scale that runs from 1 for a headwater trickle up to 6 or more for a full river), flowing directly into the Duncan River alongside Giegerich Creek, Cooper Creek and Asher Creek in the same Upper Duncan tributary band. Oasis Creek, a short 2 km creek with no direct fish record of its own, joins Houston as a child tributary. No channel-geometry (width, gradient, discharge) survey has been logged for Houston Creek itself.

The named-line fish record for Houston Creek is short but consistent: three direct observations, all bull trout, no other species logged. What carries the water is spawning-habitat context rather than catch volume. BC Hydro and Okanagan Nation Alliance monitoring (report DDMMON-5) tracks bull trout that pass Duncan Dam upstream through the Upper Duncan, and identifies Houston Creek and the Westfall River as likely the two most important bull trout spawning tributaries in that monitoring context, with adult fish tracked on the Upper Duncan mainstem from the Giegerich Creek confluence upstream past the Houston Creek confluence. Those Duncan-system bull trout intermix with Kootenay Lake fish and are managed provincially as one population, so Houston's role sits inside a basin-scale recruitment story rather than an isolated headwater fishery. No guide or outfitter names Houston Creek directly; nearby lower Duncan River guide coverage does not extend to this upper tributary.

No hatch survey is on record for Houston Creek itself. The working cold small-tributary pattern seen through the Upper Duncan is juvenile trout and char, sculpins or fry where it connects to larger water, plus stoneflies, caddisflies, mayflies, midges and terrestrials. Where it is legal and away from redds or staging fish, that points to an Elk Hair Caddis, Adams, Stimulator, Royal Wulff, Prince Nymph, Hare's Ear or Pheasant Tail, plus a small Woolly Bugger or sparse sculpin/fry streamer for any resident char holding off the spawning window. Do not fish eggs over visible redds.

No road/FSR access, tenure or fishable-reach detail has been confirmed for Houston Creek. Treat it as a scouting objective inside the Upper Duncan drainage rather than a mapped destination until a route is verified on the ground.
