Uatumã River

Coordinates: 2°34′31″S 58°09′03″W / 2.57528°S 58.15083°W / -2.57528; -58.15083 The Uatumã River is a river flowing through the state of Amazonas in the Manaus area of Brazil. A tributary of the Amazon River, it is known for its extensive peacock bass population.[1]

During the wet season starting in December, water levels can rise some 25 to 40 feet. Water levels have been strongly affected by the building of the controversial Balbina Dam on the river in the mid to late 1980s to generate electricity. The hydroelectric dam generates an average of 112.2 MW of electricity from the river system and floods a total of 2360 km2 of rainforest around the Uatumã river[2]

Uatumã Biological Reserve established in 1990 is a nature reserve around the river in the municipalities of São Sebastião do Uatumã and Itapiranga.[3]
