Amazon Basin Fishing Report 18th October 2022


Over the week we had 14 anglers from Brazil, 12 anglers from elsewhere in South America, and 14 from the US. See tally in the chart below, which excludes 2 large Arapaimas, 12 large Catfish, and a multifarious array of other tropical less aggressive species such as the Jacundá, Apapá, Cachorra, Oscar, Aruana, Wolfish, Pacú, Bicúda, and Piranha.

The lower than average tallies in quantities and trophies are caused by high water levels still pouring out of the jungle in our Matupiri, Igapo-Açu and Roçado exclusive rivers, which are our two zones with the lowest water levels across our 1000 mile diameter of private fisheries.


Looking forward, we know incoming anglers are interested in knowing where all six of our River Trains will be operating in the months ahead. The key is expected water levels, of course, across our 10 Private Rivers. River Plate is the only company in the Amazon with enough private waters to move anglers around as needed for optimal conditions.
Although our guests are having great angling, water levels at the Roçado in the North West Dry Zone and both the Matupiri & Igapo-Açu in the South West Dry Zone are slightly high (See “Fishing Zones” map below), and will likely remain so for the for the next 10 days, given above normal rainfall in the area for this time of the year.

We base our water predictions in the North West Zone and South West Zone on Today’s and Last Week’s 10-Day Rainfall Forecast (accumulated inches). These forecasts are for the towns listed below in red which affect both zones mentioned

Today’s 10-Day Forecasts for the towns in the North West Zone are as follows:

  • Villa Bitencourt: 5.41 inches (Marked as “VB” in the map below)
  • Japura: 4.50 inches (Idem “Jap”)
  • Santa Isabel do Rio Negro: 2.78 inches (Idem “SIR”)
  • Sao Gabriel da Cachoeira: 3.54 inches (Idem “SGC”)
  • Maraa: 4.23 inches (Idem “Mar”)
  • Barcelos: 2.34 inches (Idem “Bar”)

Today’s 10-Day Forecasts for the towns in the South West Zone are as follows:

  • Borba: 2.57 inches (Marked as “Bba” in the map below)
  • Novo Aripuana: 2.06 inches (Idem “NA”)
  • Autazes: 1.83 inches (Idem “Aut”)

Last Week’s 10-Day Forecast WAS as follows:

  • Villa Bitencourt: 4.48 inches (Marked as “VB” in the map below)
  • Japura: 3.79 inches (Idem “Jap”)
  • Santa Isabel do Rio Negro: 1.60 inches (Idem “SIR”)
  • Sao Gabriel do Cachoeira: 2.23 inches (Idem “SGC”)
  • Maraa: 2.20 inches (Idem “Mar”)
  • Barcelos: 1.84 inches (Idem “Bar”)


  • Borba: 1.29 inches (Idem “Bba”)
  • Novo Aripuana: 1.78 inches (Idem “NA”)
  • Autazes: 1.83 inches (Idem “Aut”)

Our water-level predications are not just based on immediate rainfall forecasts but also on longer term (3-month) forecasts for unusual (or what is called anomalous) rainfall across all of our fishing zones. In the above illustration, no unusual rainfall is expected in the white areas for the next 3 months.

Note that the North West Zone is in light blue, meaning that it is expected to receive more rainfall than normal for this time of the year. In contrast, the South West Zone is almost completely in white, meaning that it should receive the usual rainfall for this time of the year.
