The Rio Marié is born in the Northwest corner of the Brazilian Amazon, up near the Colombian border. It is a tributary of the upper Rio Negro. The Rio Negro basin is the largest drainage of "black" water in the world, with approximately 710,000 km² of land are and is currently one of the most preserved regions in the Amazon, with less than 0.5 % of deforestation. The Rio Negro is its main river, the second largest tributary of the Amazon River, which has the headwaters in the Serra do Junai Hills in Colombia and runs approximately 1700 km to its confluence with the Solimoes River near the jungle city of Manaus.
The Rio Marie is entirely located inside a far-reaching Indigenous Territory and approximately 500 miles northwest from Manaus, which is our operation's base point and the most important city in Brazilian Amazon.

The fishing operation utilizes an area of more than 2 million hectares. This untouched environment has more than 800 kilometers of rivers, more than 180 known creeks, 60 lakes, and three major tributaries. Plenty of water to keep us busy chasing fish that rarely will see humans and anglers.

This is the first exclusive fly-fishing only project allowed and supported by the Brazilian Government. Official Environmental Institutes worked together with the Indian Association to create the very first official sport fishing operation in Brazil inside an indigenous Indian Territory. This brings a new level of commitment and cooperation between all parties associated inside the Amazon region.



The majority of the indigenous population in the middle Rio Negro identify themselves as Baré which is originally from the region. There are also several groups that have moved from the upper Rio Negro, especially Tukano, Tariana and Baniwa. In the middle Rio Negro the different indigenous groups often live in the same communities or neighborhoods, and marry among themselves and with non-indigenous, creating a multi-ethnic population profile.

Each community operates as an independent socio-political unit. Each has its own manager – a type of captain or tuxaua (chief) – and a patron saint if the majority of the population is Catholic.
There is a common pattern in terms of how each family and community agrees to use areas, typically: forest clearings for annual crops (roças ), stretches of rivers and igarapés (creeks) where they fish, and areas used to collect forest resources (for instance, piaçabais – clusters of piassaba palm tres and castanhais – clusters of Brazil nut trees). Normally the use of these collection areas is shared.
