Even though Kražantė's basin is somewhat smaller, it should be considered the main river. Dubysa is mainly fed by rainfall and melting snow, therefore its water levels change rapidly. The maximum depth is about 4 m.
The valley of Dubysa is one of the highest and widest in Lithuania
. The valley reaches 20-40 m in height and 300-500 m in width. It was formed during the last glacial period. Near Lyduvėnai there is a railroad bridge across the valley, which is the highest and longest such bridge in Lithuania. The bridge was first built by the Germans during the World War I
