The dependence of the average water level in the Ob River at the Novosibirsk water post on the discharge rate to a hydroelectric power station is being investigated. The stochastic approach is used to model this dependence. As a result of the analysis of an array of statistical data a two-component mathematical model has been obtained. The simultaneous use of the Probit probability determination model and the construction of a regression straight line result in a nonlinear relationship between the water level and the discharge rate, which allows for a more accurate flood forecast.
