Predictions of time-varying salinity under arbitrary gate operations are presented of a tidal lake and its inlet. Particular regard is given to the modeling of salinity and gate operations and the applying the Markov process with Kalman filtering. In contrast to previous papers that predict only water levels the present paper also estimates salinity downstream the gate and of the tidal lake, simultaneously. It is postulated that present water level and salinity are expressed by the explicit linear functions of water levels, salinity, and gate operations at the other and the same positions in the past step. Using physically plausible estimate for these parameters in the functions the results of the predictions are in good agreement with observation.
