Skinner carries an official Kootenay Land District name (key JBMHT, map 082K11), fixed at 50.538611, -117.205000. It runs stream order 5 (mid-to-high on the 1-to-6+ network scale, well down the network toward river scale) for roughly 10 km before joining
Healy Creek, which in turn reaches the Lardeau River below
Trout Lake. The channel-geometry numbers read small and steep (~9.1 m wide, narrow; ~8.26% gradient, steep; ~1.99 m³/s peak mean-annual discharge, low flow), consistent with a headwater tributary rather than a mainstem.
