パラグアイ川
The Paraguay River basin includes several distinctive habitats, ranging from very clear waters such as Rio da Prata (pt) near Bonito in the upper part to the sediment-rich Bermejo River in the lower part. The suspended load of the Paraguay River is about before the inflow of Bermejo, but rises to about after. Directly after the inflow of Bermejo River, the pH of the Paraguay River may reach up to 8.2. The typical pH of the Paraguay River is 5.8—7.4 in the upper part (defined as the section before the inflow of the first non-Pantanal tributary, the Apa River) and 6.3—7.9 in the lower part.
