Big, turquoise and lake-fed (pulled live from Argentina Flows — Caud.Rios + Caud.Percy crossing the border from Argentina on chilewaterlevels.com), so it stays clear when other rivers blow out. Mostly a drift-boat river; wade the edges and side channels at lower flows.
The app's suggested gear: 6 wt (9 ft, WF floating) for dry-dropper & hoppers + 7 wt (200–250 gr sink-tip, 0X–2X fluorocarbon) for streamer banks.
The app's starting estimate (not yet validated by guides): low and clear below 180 m³/s · ideal 180–330 m³/s · high 330–480 m³/s · blown out above 480 m³/s (in cfs: 6,357–11,654–16,951). Right now: 269 m³/s (9,500 cfs); the river is in its ideal range on the app's scale.
