The quest of this research is to find the most appropriate probability distribution function that
best approximates the water level in the Tono dam. The data used consist daily water level
recordings from January 2010 to January, 2017. The sample size of the data is 2570. However,
2195 data points were used in the analysis whilst the remaining 375 was used for validation.
After various probability distribution functions were fitted to the data, it was observed that the
Weibull distribution best fits the data. From the Weibull distribution fitted, it can be observed
that the level of the water in the Tono dam is dwindling with time.
