Table 6: Changing points detected in the monthly streamflow time series of selected stations. While detecting gradual and abrupt changes in the hydro-climatic variables could be interpreted as signals for climate change and anthropogenic drought, respectively, linking these changes to those identified by monitoring the lake's surface area requires further analysis. From a statistical analysis standpoint, one can attempt to relate the abrupt changes in surface area to those processes revealed by the time series of hydro-climatic variables.
