Ogelston sits at 50.70009, -116.32456, 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 9 km before joining
Frances Creek, which drains into
Forster Creek and then the
Columbia River. A regional fish habitat survey recommended resampling reach 3 of Ogelston because dry, low-flow conditions at the time limited confidence in the result, even though it noted suitable spawning and rearing habitat nearby, a reminder that an empty record here reflects thin, low-flow survey coverage as much as an empty creek. Fish moving up from the Columbia are blocked well downstream by a cascade and a roughly 3 m falls in lower Forster Creek, so anything living this high in the system would be a resident or lake-connected population rather than a mainstem migrant.
