Quick Summary

The Tiszalök Dam, built in 1954, is located on the Tisza River in Hungary. It creates the largest reservoir in the country and serves a dual purpose: generating hydroelectric power and supplying year-round irrigation water to the Hajdúság and Hortobágy plains through the Eastern Main Canal, which connects the Tisza and Berettyó rivers to the Körös River. The Tisza River itself is a major tributary of the Danube, originating in the Carpathian Mountains and flowing through Romania, Ukraine, and Hungary before joining the Danube near Belgrade, Serbia. The river's flow is characterized by significant seasonal variations and floods, leading to the construction of extensive flood-control levees along its course.1
