NRCan/GeoGratis lists Fir Creek as an official Kootenay Land District creek (key JAWUL) at 49.670000, -114.781944. It flows into
Michel Creek, which in turn joins the
Elk River at Sparwood. A 2016 tributary evaluation for Teck found steep step-pool and cascade habitat over cobble, boulder and gravel substrate, with only 37% of the creek's listed stream length connected to the Michel Creek main stem. That connectivity ends at a natural gradient barrier roughly 7 km above the confluence; the report found no fish above it, so any fish-presence claim on Fir Creek should stay tied to the lower, connected reach, not the mapped length of the whole system.
