Wilkie Creek (4-30) is individually listed as No Fishing in the current Region 4 table. No separate entry exists for Humphries Creek, so do not assume this child water is open until the closure question is confirmed with the official synopsis or a regional fisheries office.

The creek carries an official Kootenay Land District name, at 50.636944, -117.547500. It runs stream order 3 (near the headwater end of a scale that runs from 1, a trickle, up to 6 or more for a full river) and stretches roughly 5 km before joining wilkie creek, which in turn drains toward duncan lake by way of Trout Lake and the Lardeau system. Bcfishpass channel-geometry data puts the median width at roughly 2.9 m (narrow), the median gradient at roughly 17.96% (steep) and the peak mean-annual discharge at roughly 0.287 m³/s (low flow), a small, steep headwater profile. Water Survey of Canada lists a station reference for Humphries Creek near Trout Lake (08NH138), which would support a future flow check if the creek's legal status is ever resolved.

The named-line fish-record extraction found zero direct observations on Humphries Creek itself. What it does carry is the same inferred forage context as the wider Wilkie / Trout Lake system: kokanee, sculpin and juvenile fish moving through connected water, with small mayflies, caddisflies, stoneflies and terrestrials as the likely aquatic and terrestrial food base if any reach of the creek proves fish-bearing. None of that is confirmed on Humphries itself, so no fly recommendation follows from current evidence.

No specific access route, trailhead or parking area for Humphries Creek has been confirmed. The wider Wilkie Creek drainage sits in Trout Lake / Lardeau mining country, reached historically by dirt road from the north end of Trout Lake, but that context describes the area generally rather than a confirmed Humphries Creek approach.
