Madias Creek runs stream order 4 (mid-range on a scale that runs from 1 for a headwater trickle up to 6 or more for a full river), stretching roughly 12 km before it reaches Windermere Lake. The channel measures a median width of about 5.0 m (narrow), a median gradient of about 6.02% (moderately steep), and a peak mean annual discharge of roughly 0.227 m³/s (very low flow), the profile of a small, tight tributary rather than anything approaching driftable water. No fish have been directly recorded here in provincial inventory data, though the creek is classified as reachable from recorded fish-bearing water with no barrier between, which is why the connected system's species list (westslope cutthroat trout, bull trout, rainbow trout, kokanee and others) is carried as inferred rather than confirmed.
A July 2024 wildfire burned through the Crooked Tree and Madias Creek area, prompting an RDEK evacuation order later downgraded to an alert. Post-fire sediment loading, road washouts and access changes are the kind of thing that shows up on a creek like this and has not been field-checked since.
