✦ Synopsis

A reservoir for drinking water supply was studied a t 10 day intervals for one season. Changes in bacterial microscopic counts and chlorophyll and algal biomass showed a similar pattern. Bacterial peaks usually lagged slightly behind the algal maxima. Average volumes of bacterial cells, corrected for shrinkage, were mostly lower than 0.2 pm3. The average concentration of bacterial C in water was estimated t o be 18 pg * 1 (from a volume biomass of 0.09 mm3 per litre). Several years' fluctuations in bacterial numbers were compared with hydrological data and phytoand zooplankton changes.
