We analyzed 8 longitudinal transects covering highly variable seasonal and spatial circulation patterns. To compare biological longitudinal gradients under fluctuating water levels and different water circulation patterns, we applied a model based on the relative distance of a sampling station from the river inflow. Under different hydrological scenarios, the model characterized epilimnetic food chain successions and locations of peaks of heterotrophic microbes and plankton along the longitudinal gradient. The amplitude of microbial peaks reflected the proportion of nutrient and organic carbon rich river water that mixed into the reservoir epilimnion. Thus, the relative input of river water is suggested to be a useful predictor of the amplitude of the development of the epilimnetic microbial food webs in highly loaded canyon-shaped reservoirs.
