Poland water levels: Solina Lake bed exposed and Vistula River erosion

Hydrological drought and environmental changes are affecting major water bodies in Poland. In the Bieszczady region, the Solina Lake has seen significant portions of its bed exposed, particularly in shallower areas and branches near Wołkowyi. This phenomenon is driven by a lack of rainfall and a significant imbalance between inflow and outflow; currently, approximately 1 cubic meter of water enters the reservoir per second, while 7.5 cubic meters are discharged. While the sight has attracted tourists, experts clarify that the entire lake is not drying up.

In Warsaw, the Vistula River is also experiencing visible changes, with sandbars and stones emerging from the water. However, researchers from the Polish Academy of Sciences and the Warsaw University of Life Sciences note that the perceived drop in water levels is not solely due to decreased volume. Instead, riverbed erosion, channel narrowing, and the removal of aggregate have altered the river's geometry. While the current flow of approximately 150 cubic meters per second is lower than the long-term average of 600 cubic meters per second, it does not yet represent a catastrophic shortage compared to historical lows.
