Blacktail Creek flows into
phillipps creek, which in turn drains to the
kootenay river. It runs stream order 3 (low on the network, on a scale that runs from 1 for a headwater trickle up to 6 or more for a full river), stretches only about 1 km in the mapped local model, and carries zero fish records in the local inventory extraction, in line with a very short, low-order headwater feeder.
