On paper Brown Creek falls under the Lardeau Creek / Trout Lake tributary bucket, bull trout catch-and-release unless a water-specific exception applies, but it carries no confirmed sportfish population. Confirm the current synopsis before fishing the drainage.

Brown Creek carries an official provincial place name in the Kootenay Land District, at 50.632778, -117.311389. The name repeats elsewhere in B.C., so this page covers specifically the Lardeau Creek watershed water, distinct from the Brown creeks in the Duncan Lake and Upper Arrow Lake watersheds. It drains northeast into lardeau creek from the divide with Laughton Creek, on ground shared with the old Foggy Day mineral prospect. It runs stream order 4 (mid-range in the network, on a scale that runs from 1 for a headwater trickle up to 6 or more for a full river), stretches roughly 3 km, and holds zero fish records in provincial inventory data, consistent with its no-sportfish designation.

With no confirmed sportfish and no published guide coverage, there is nothing here to recommend as a destination. Treat Brown Creek, like neighboring North Brown Creek and ottawa creek, as habitat and access context within the Lardeau Creek watershed rather than a place to plan a day around.

There is no fishery to organise access around on Brown Creek itself. Anyone moving through the old Gainer Creek mining ground toward lardeau creek should treat the surrounding old roads and workings as an access and hazard question first, not a fishing one.
