    Source

  • Threshold postureGauge-linked range used for live scoring

    The cited route guidance is tied to this gauge and reach; hazards, closures, weather, and local inspection still override the score.

    Source

  • Safety and land managementCurrent manager notices override this record

    The BLM guide warns that high or low water, shifting channels, cottonwood strainers, diversion structures, bridge piers, cold water, and remote rescue can affect any reach. Stay off private banks and carry first-aid, repair, and emergency communication appropriate to the corridor. The guide directs boaters into the left/north channel approaching Salmon Island and identifies additional diversions near Salmon.
