The contribution deals with the recorded impacts of human activities in the area of the upper river basin of the Lužická Nisa in North Bohemia. A method of binary mass curves has been used for the interrelation between precipitations and the drainage front mean monthly data both for vegetation (April - September) and non-vegetation (October - March) periods for 1951-1990. The variations in the mass curves are confronted with events in the drainage area ascertained in archives and literature.
