No Bloom Creek-specific exception is published. By default it likely falls under the nearby Gold Creek (4-3) listing, trout and char catch-and-release with a bait ban, but that parent listing itself has not been matched against the official regulations table. Confirm both directly in the current synopsis before fishing.

The creek runs about 25 km at stream order 5 (well down the network toward river scale, on a system that runs from 1 for a headwater trickle up to 6 or more for a full river) before joining Caven Creek near 49.10047, -115.47617. Channel-geometry data puts the median width at roughly 11.5 m, narrow, with a median gradient around 1.04%, gentle, and a peak mean-annual discharge near 1.7 m³/s, a low-flow signal typical of a small, headwater-fed tributary. Sixty fish records across five species groups is a good habitat signal for water this size.

With bull trout and dolly varden alongside westslope cutthroat, rainbow and mountain whitefish, Bloom Creek reads as a careful-handling, conservation-sensitive water rather than a numbers stream. Its food base follows the regional East Kootenay pattern: caddis, mayflies, smaller summer stoneflies, sculpin and late-season terrestrials make up the working forage groups.

Fish it with the standard small East Kootenay dry-fly box: an Adams or Royal Wulff up top, an Elk Hair Caddis or Stimulator through summer, ants and beetles for terrestrial season, and a Hare's Ear or Prince Nymph plus a small dark streamer worked slow for the char.

Legal access into Bloom Creek has not been confirmed. No named trailhead, road or crossing turned up in the record, and the creek may be more habitat water than a fishable lower reach, so treat a trip here as an access-and-conditions check rather than a guaranteed day on the water.
