Region 4 lists Columbia Lake's tributaries as closed to fishing except Dutch Creek. Major Creek sits right on the Columbia Lake / upper Columbia River headwater edge, so until the exact boundary is confirmed it should be treated as covered by that closure. Confirm the current synopsis before fishing anywhere nearby.

Natural Resources Canada lists Major Creek as an official Kootenay Land District watercourse at 50.254722, -115.876389. Stream-order, length and channel-geometry figures are not on record for it, and provincial fish-inventory data shows zero direct local observations on Major Creek itself, consistent with a small, lightly surveyed lake-edge tributary rather than a mapped fishery.

There is no angling case to make here. Region 4 lists Columbia Lake's tributaries as no fishing except Dutch Creek, and Major Creek sits close enough to that boundary that the working rule is to leave it alone until an official in-season update or a confirmed hydrological boundary says otherwise. No local fish records support a fishery even setting the closure aside, and no guide service was found advertising Major Creek specifically. kootenay troutfitters operates in the wider Columbia Valley and is the nearest guide context, but that does not extend to this creek under the current closure.

No named trailhead, launch or public access point is on record for Major Creek. Given the likely closure and the absence of confirmed fish, there is no reason to plan an access route here beyond general awareness of its location on the Columbia Lake headwater edge near Canal Flats.
