Barbour sits at 50.40007, -116.28079, running stream order 3 (low on a scale from 1 for a headwater trickle to 6 or more for a full river) for roughly 6 km before joining
Toby Creek, which drains into the upper
Columbia River. Government fisheries work on the broader Toby/Jumbo system found bull trout throughout Toby Creek and cutthroat concentrated in the middle and lower Jumbo Creek reaches, but flagged the family's smaller tributaries, Barbour among them, as flashy, glacial-influenced water with limited winter habitat and low nutrient productivity. Nothing in that work singles out Barbour as either a confirmed fishery or a barren stream; it simply was not surveyed directly.
