The water is an important component for human beings, animals, autotrophs and heterotrophs. Actually, human beings continuously adopted to their physical environment. Due to the increased population, human needs more water for drinking, agriculture, etc. The proposed paper explained in detail, the standard measures like mean, standard deviation, co-efficient of R2 and auto-correlations of the downscaling data in hydrology. The new model is MLE by Gaussian distribution is a method that we will find the values of that result are best fit the data sets. Simple downscaling approach, in general, can perform well as the parametric method, generate the observed water level using SELGA and SELSGA approaches. Maximum Likelihood Estimation is the best prediction using parameters of water level data sets. The new model is used, the present proposed article is to predict future values using stochastic extended linear group average and stochastic extended linear semi-group average on generated downscaling data sets.
