Mineral Creek sits at 50.34697, -116.30254, 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 12 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 characterized the family's smaller tributaries as flashy, glacial-influenced water with limited winter habitat and low nutrient productivity. Mineral Creek's own six records, split between Dolly Varden and bull trout, read as consistent with that coldwater char signature rather than an unusually strong fishery.
