Sultana sits at 50.43170, -116.37426, running stream order 4 (mid-range on a scale from 1 for a headwater trickle to 6 or more for a full river) for roughly 3 km before joining
Delphine Creek, which in turn flows into
Toby Creek and the
Columbia River. Government fisheries work on the broader Toby/Jumbo system found bull trout throughout Toby Creek and mountain whitefish in the lower reaches, but it flagged the family's smaller tributaries, Sultana among them, as flashy, glacial-influenced water with limited winter habitat and low nutrient productivity. Nothing in that work singles out Sultana as either a confirmed fishery or a barren stream; it simply was not surveyed directly.
