The article describes a species diversity of freshwater mussels in the waters of the high and low of the floodplain, lakes and fens of the Chulym River basin. There is the dependence of biodiversity of mollusks from the acidity of the environment in floodplain waters of low and high level of the fens and lakes. The richest in species diversity of freshwater molluscs are lakes of low floodplains, where pH – indicators of environment are neutral, and only in the flood they shift toward the low one. In lakes of high floodplain, the pH reaction is almost always weak acidic, and only in years with strong flood it shifts to neutral, thus it affects on the malakofauna of these biotopes. The smallest species of freshwater molluscs are in lowland bogs, where pH reaction is weak acidic but in dry years it shifts toward the acidic one
