The Rio Corda, also historically known as the Rio Capim, is a river flowing through the state of Maranhão in Brazil. It has a length of approximately 250 kilometers and drains a basin area of about 4,700 square kilometers. The river is a significant geographical feature in central Maranhão, notably flowing through the city of Barra do Corda. There, it meets the Mearim River, and the confluence of their dark-hued waters creates a notable visual spectacle. For paddlers, general access points, boat ramps, and facilities for launching and enjoying a day on the water are indicated as available. The river's character is shaped by its role in the regional landscape, passing through areas of human settlement like Barra do Corda, which is a city of around 89,000 people. This suggests the paddling experience may combine natural river scenery with proximity to local communities. The historical significance of the watercourse is reflected in its dual name, Corda ou Capim, indicating a traditional usage or recognition under both titles. Quantitative details such as seasonal water temperature patterns, specific water quality, or detailed route recommendations for day trips are not available.
