Ribeirão das Anhumas is a stream located in the state of São Paulo, Brazil, specifically within its basin in the city of Campinas. It is important for paddlers to note that, according to official sources, this water body is not considered appropriate for navigation or for bathing. This indicates significant safety and suitability concerns that must be taken into account before any trip planning. The stream flows through a basin that includes sub-basins such as Alto Anhumas and Córrego do Mato, and the surrounding area has been the subject of studies analyzing physical and chemical soil degradation at the edges of remaining forest fragments. Access points, boat ramps, and facilities for paddlers are available, though no detailed locations or descriptions of these amenities are provided. The stream is known to be a fishing location, with species including Redbreast tilapia, Redtail catfish, and Barred sorubim, which suggests the presence of aquatic wildlife. However, the explicit statement that the stream is not suitable for navigation, combined with noted water quality concerns from soil degradation studies, presents a clear picture of a waterway with potential hazards. Paddlers should seek authoritative, current local guidance regarding any restrictions, water quality, and safe access points before considering an outing on Ribeirão das Anhumas.
