In 1946 and 1988 The Nile River burst out its banks and caused great damages to the human live in The Nile River State. These damages can be minimized by using an alarm system. This paper investigates on the use of mathematical formulas created by the ministry of irrigation and water resource for the period after the construction of Tekeze dam (2009). The stages data for the year 2012 were used for the investigation and square root correlation coefficient method was used to justify the results. The results show the formulas can be used to predict 1 and 2days stage at all stations to the south of Atbara with a reasonable correlation coefficient, but more works should be done on the current formulas for the northern part of the state
