Boundary Creek carries no individual line in the Region 4 (Kootenay) regulations table, so the regional stream defaults apply: closed Apr 1 to Jun 14, trout and char catch-and-release Nov 1 to Mar 31, single barbless hook required year-round, and a freshwater licence for anglers 16 and over. Confirm the current synopsis before you fish.

The coordinate this page uses, 49.0000, -116.52922, is the FFSBC/FIDQ release point recorded against the stocking data, not a confirmed mouth or named reach, so treat it as a starting pin rather than a precise location. Provincial stocking records file the waterbody under the Kootenay Lake watershed group, which means the creek's water eventually reaches the Kootenay River by way of Kootenay Lake, though the exact tributary chain between here and the lake has not been confirmed for this page.

No fish-inventory records beyond the stocking log, no guide coverage and no fishing reports exist for Boundary Creek, so there is nothing here to confirm as a modern destination. The historic releases used recognizable BC hatchery stock, Pennask, Gerrard Creek and Beaver strain rainbow trout eyed eggs, brook trout fry and eggs from a Spokane, Washington source and Boundary strain broodstock, plus a single 1931 release of 5,000 westslope cutthroat fry sourced from the Cranbrook water reservoir. That mix reads as an active put-and-take program in its day rather than a one-off conservation stocking. Whether any of it carried over into a self-sustaining population, or whether the creek fishes at all today, is unconfirmed.

No access route, launch or trailhead is confirmed for Boundary Creek. Anyone scouting the East Kootenay stocking record in person should start from the release-point coordinate above and work outward; nothing more specific has surfaced. Kootenay River and the wider Kootenay Lake watershed are the eventual receiving waters downstream.

For an angler judging whether this creek is worth a look, the release history below is effectively the whole fishing report. Provincial FIDQ/FFSBC data records 16 releases totalling 289,344 fish between 1927 and 1957: rainbow trout eyed eggs and fry, brook trout eyed eggs and fry, and one westslope cutthroat fry release. The largest single release was 45,000 brook trout eyed eggs in 1931; the last was 20,000 brook trout fry in 1957.
