A qualitative and quantitative analysis of the plankton of two ponds in Kathmandu Valley (Nepal) was made. Vertical and seasonal variations of the plankton of one pond were studied as well as physical and chemical properties of the water (temperature, visibility, electrical conductivity, pH‐value, alkalinity). During the dry winter the number of plankton species and individuals was low. In summer, before the onset of the monsoon mass developments of different μ‐algae and Ceratium hirundinella occurred.
