The Catuá-Ipixuna Extractive Reserve is divided between the municipalities of Tefé (33.85%) and Coari ( 66.15%) in the state of Amazonas.

[3] The reserve is in relatively flat country with altitudes of around 40 metres (130 ft) in the basins of the Catuá and Ipixuna lakes and the Solimões River.

Commercial exploitation of timber resources is only allowed on a sustainable basis and in special situations.

[6] On 28 July 2004 the reserve, with an area of 215,342.879 hectares (532,123.84 acres) was recognised as meeting the needs of 300 families of small farmers, who would qualify for PRONAF support.

Fish in the two lakes include abundant members of the genera Potamorhina, Psectrogaster and Curimata.

Important bird species include the toco toucan (Ramphastos toco) and Klages's antwren (Myrmotherula klagesi), both in the extreme west of their ranges, and the little-known wattled curassow (Crax globulosa) of the várzea, which may be threatened with extinction.

The main source of income for the residents is production of flour, and the sale of cassava and bananas.
