Lum Creek is a small tributary of Tanglefoot Creek in the upper Bull River drainage, joining it at roughly 49.66255, -115.45408. It is one more thread in a cluster of upper Bull headwater creeks feeding Tanglefoot, which itself carries recorded westslope cutthroat before flowing into the Bull.
The water
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.
The fishing
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.
A lineage note, not a destination
Access and the rules
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.
Before you fish
Conditions
- Navigability: small and steep (median width ~3.9 m, narrow; gradient ~6.82%, steep; peak mean-annual discharge ~0.508 m³/s, very low flow), consistent with a headwater tributary rather than fishable mainstem water.
- Stocking: no stocking record. Any fish present here would be wild.
