Gauge data · Rio Negro
Water Tracker
Water level decides everything in the Amazon. When the Rio Negro drops, bait and fish get pushed out of the flooded forest and into the lagoons and channels, and that is when the fishing turns on. Here is where the river stands right now at three gauges, compared with last year.
How to read it: the gold line is this year, the dotted line is 2025, and each dot is an official reading from the Serviço Geológico do Brasil. Tap a river or a pin on the map to switch.
