The Timonha River is a river of Ceará state in eastern Brazil. Like many small rivers of northeastern Brazil, the Timonha River dries up between July and November and only flows during the rainy season.[1] According to a survey by the United States Hydrographic Office, the Timonha River is too small to allow passage by boats.[2]
The river is part of the Timonha-Ubatuba estuarine system, which has the largest mangrove ecosystem in Ceará.
The river delta is protected by the Delta do Parnaíba Environmental Protection Area, created in 1996.
