Olivia Creek is a small headwater tributary of East Sulphur Creek in the upper Bull River drainage. No fish survey has produced a direct record for this reach, so this is a creek to read as habitat context rather than a destination to plan a day around.
The water
The creek runs about 6 km and sits at stream order 3 (a low position on the 1-to-6+ scale where 1 is a headwater trickle and 6+ is a full river). It flows into East Sulphur Creek, which in turn flows into Sulphur Creek and then the Bull River on its way to the Kootenay River. The provincial waterway model carries an inferred westslope cutthroat signal here, matched down from the wider network rather than observed directly. Inferred means modeled, not confirmed by anyone standing in the water.
The fishing
With no confirmed catches and no dedicated guide coverage, Olivia Creek is not a where-to-fish answer, it is a how-the-watershed-is-built answer. If a westslope cutthroat trout does turn up here, the small-stream program would be tiny dries, ants and beetles fished on light nymphs and terminal tippet, matching the scale of a narrow headwater creek. Treat that as a starting hypothesis, not a confirmed pattern for this reach; nobody has verified that it fishes at all. The better use of this water is as cold-water refuge and rearing habitat for the fish recorded further down the Sulphur Creek and Bull River system.

Access and the rules
No named trailhead, forest service road spur or parking area has been confirmed for Olivia Creek. Until a route is documented, treat access here as unconfirmed.
Before you fish
Conditions
- Navigability: no channel-geometry survey has been logged for Olivia Creek itself. Its nearest order-3 counterpart in the same upper Bull cluster, Ruault Creek, runs narrow and moderately steep (median width ~3.4 m, narrow; gradient ~7.35%, steep; peak mean-annual discharge ~0.187 m³/s, very low flow). That gives a rough sense of the drainage type, though it is not Olivia Creek's own measured data.
- Stocking: no stocking record. Any fish present here would be wild.
