No water-specific exception is listed for Ottawa Creek in the current Region 4 table, and local fisheries data marks it no-sportfish. On paper it would carry the same regional stream default as the wider Lardeau Creek drainage: trout and char catch-and-release Nov 1 to Mar 31, streams closed Apr 1 to Jun 14, single barbless hook year-round. Confirm the current synopsis before working the drainage.

Ottawa carries an official provincial name in the Kootenay Land District, recognized on the NRCan gazetteer at 50.624722, -117.300833. It flows northeast into Lardeau Creek, which in turn drains to Trout Lake. It runs stream order 3 (low 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 6 km, and has zero fish records in provincial inventory data, in keeping with a small, no-sportfish headwater creek high in mining country.

With no confirmed sportfish, no guide coverage and no fishing reports, there is nothing here to recommend as a destination. No food or hatch survey has been logged for the creek either. Treat Ottawa Creek as habitat, access and hazard context within the Lardeau Creek drainage rather than a place to plan an outing around.

There is no fishery to organise access around here. The creek sits in old mining country toward the head of the Lardeau Creek drainage; treat any road or trail into the area as unconfirmed for condition, tenure and closures until checked directly with the relevant land-use authority.
