No gauge on this water — readings are regional estimates from weather, not a live gauge.

How these readings are sourced

Weather-only: no live gauge wired. Braided glacial river — carries snow/glacial colour, rises with rain and snowmelt; one gauge can't represent all fishable channels. Salmon move on a dropping, clearing river.
