The runoff performance in the Weser river basin district is in most years characterized by frequent floods during the winter and a low water period from June to October. The flooding period consists mainly of two big events: The first normally occurs in December/January wheras the second one im March/April is caused by melting snow in the Central Mountains. With that the Weser can be classified as pluvio-nival type regarding its runoff performance. The natural low water period is especially significant in Werra and the upper Weser, but is compensated in the Weser by water supplied from the Eder dam into the river Fulda. The tidal Weser and the river Jade (Jadebusen) are exposed to the threat of storm surges. To characterize the hydrological conditions in the Weser river basin district the runoff figures of the gauging station at important river stretches are presented in the table below.
