Lum Creek has no individual regulation exception on record. As a tributary of Tanglefoot Creek, it falls under the Bull River Classified Water language, which extends to tributaries: trout and char catch-and-release on the reaches carrying that designation, Class II licence when and where open. Regional stream defaults also apply: closed Apr 1 to Jun 14, trout and char catch-and-release Nov 1 to Mar 31, and a single barbless hook required in all streams year-round. Confirm the current synopsis before you fish.

The creek runs stream order 4 (mid-low on the 1-to-6+ scale where 1 is a headwater trickle and 6+ a river) across about 6 km and roughly 15 mapped channel segments. Channel geometry puts it at a median width of about 3.9 m (narrow), a median gradient of about 6.82% (steep), and a peak mean-annual discharge of about 0.508 m³/s (very low flow), the profile of a small, technical headwater creek rather than a wading river.

No direct fish observations exist for Lum Creek itself. What is known is inferred: it sits inside the same network as Tanglefoot Creek immediately downstream, which does carry recorded westslope cutthroat, sculpin and a broader upper-Bull rainbow, dolly varden and mountain whitefish signal. That makes a reachable cutthroat presence plausible, not confirmed. Nothing about access, water quality or a fishable channel here has been checked on the ground.

No confirmed public access route, trailhead or parking area has been established for Lum Creek. It sits in rugged upper Bull River country above the Tanglefoot Creek confluence, and any route in would extend from whatever access serves the Tanglefoot drainage. Confirm road status, land ownership and current access legality before planning a trip here.
