No individual Sob Creek entry appears in the Region 4 table. Handle it as an upper Duncan Lake tributary regulation-confirmation water: Region 4's regional defaults apply (no fishing Apr 1 to June 14, trout and char catch-and-release in streams Nov 1 to Mar 31, single barbless hook required), and Duncan Lake's tributaries carry a bull trout release rule. Do not assume Duncan River mainstem exemptions, quotas or bait wording apply here unless the official table or a regional office confirms it.

Sob Creek carries an official name in the Kootenay Land District, at 50.616667, -117.049444. It runs stream order 3 (low-mid on the 1-to-6+ network scale, where 1 is a headwater trickle and 6+ a full river) and stretches roughly 4 km before joining the Duncan Lake watershed. The channel itself is small and steep: a median width around 4 m (narrow), a median gradient around 22.91% (very steep), and a peak mean-annual discharge near 0.411 m³/s (very low flow) describe a tight, technical creek rather than anything a boat or a long cast would suit.

Provincial records hold two direct kokanee observations for Sob Creek, and BC Hydro's DDMMON-10 monitoring reported numerous kokanee here during late-September 2014 bank counts, with fish holding at the mouth and pairing over gravel, spawning slightly earlier than the mainstem Duncan River. BC Hydro also used Sob Creek in its DDMMON-17 Duncan Reservoir kokanee stock-assessment and genetics work. None of that is sportfishing evidence. No trout, char or other sportfish records exist for this creek, and no fishing-guide coverage was found; Reel Adventures Fishing Charters lists Duncan Lake at the lake and charter level, not this creek specifically.

Direct hatch data has not been found for Sob Creek. The likely small-water food layer, by extension from the wider upper Duncan drainage, runs to stoneflies, caddisflies, mayflies, midges and terrestrials, plus kokanee eggs, fry and carcass or flesh pulses that can matter to the food web where legal and ethical. None of this has been confirmed on the ground here, so treat it as regional context rather than a hatch chart to fish by.

Public access, road or trail condition, and land tenure around Sob Creek have not been confirmed. Nothing here should be read as an invitation to drive in and fish; approach it, if at all, as a place to check current information locally first.
