Today the reduction of hydrological posts of supervision over a flow in the territory of Belarus is observed. Researches have shown that the quantity of hydrological posts existing today is sufficient, but the quantity of stations of supervision over an annual flow comes nearer to a critical minimal value and the further reduction of quantity of hydrological posts in the territory of Belarus is inadmissible. The analysis has shown that the required least quantity of hydrological posts should be more. Researches of optimization of quantity of stations of supervision over a flow during the shallow-flowing and full-flowing periods testify that the quantity of hydrological posts corresponds to available quantity practically for all kinds of a flow except for quantity of stations of supervision over a winter flow in shallow-flowing years.
