Hungary’s Tiszaalpár Lake rises as Danube and Tisza hit historic lows

Water officials in Hungary have raised the level of the Tiszaalpár Nagy‑tó by about 10 cm through a gravity‑driven water‑filling operation. The Kiskunság National Park aims to flood the most water‑deficient shoreline sections and protect the rare swamp rose vegetation, a process expected to take two weeks.

At the same time, the Danube and Tisza rivers are experiencing record‑low water levels. Measurements at Baján on the Danube fell to 17 cm and at Paks to –103 cm, prompting navigation restrictions and exposing decades‑old shipwrecks. River flow has declined sharply and temperatures have risen above 25 °C, leading the Paksi nuclear power plant to intensify water‑temperature monitoring. The National Water Directorate warns that prolonged drought could keep water levels low, though drinking‑water supplies remain secure.
