No separate in-season listing exists for Coppery Creek. As a Dewar Creek tributary it falls under the general St. Mary tributary rule: trout and char daily quota 1, none under 30 cm, open Jun 15 to Oct 31 unless separately listed, bait ban, and a Class II licence when and where open, tributaries included except Joseph Creek. Confirm the current synopsis before you fish.

NRCan's Geographical Names database lists Coppery Creek as an official Kootenay Land District name at 49.798611, -116.438056. It runs stream order 3 (low on the network, on a scale that runs from 1 for a headwater trickle up to 6 or more for a full river), stretches roughly 5 km, and drains into Dewar Creek, which in turn joins the St. Mary River. Wildsight's comments on the Retallack logging proposal group Coppery with Calamity and Office creeks as de facto wilderness bordering the Purcell Wilderness Conservancy, and a separate Wildsight report notes proposed logging aimed at the Westfork, Dewar and White Creek drainages while describing the upper St. Mary as comparatively intact.

The two confirmed cutthroat records are presence signal only, not proof of a fishable or resilient population, and they say nothing about access. The channel geometry (median width ~3.6 m, narrow; gradient ~10.95%, steep; peak mean-annual discharge ~0.221 m³/s, very low flow) reads as small, technical pocket water, more scouting creek than day-trip target. If a fishable reach is ever confirmed, start with the small-stream food base used across the upper St. Mary: small stoneflies, mayflies, caddisflies, midges and summer terrestrials, fished with small-stream dry-fly tactics.

No named trailhead, parking area or put-in has been confirmed for Coppery Creek. BC Parks describes the gravel road corridor along the St. Mary River and Dewar Creek, the same general system, as remote, used by industrial logging traffic, and the route into the wider Purcell Wilderness Conservancy backcountry. Treat any approach to Coppery as backcountry travel rather than roadside fishing until a specific access point is confirmed.
