The water level in Lithuanian rivers was low throughout July. Even after enough days of rain, the water level in the rivers rose slightly as most of the precipitation was absorbed by the dry land. The hydrological regime of Nemunas and Neris, Lithuania’s main rivers, has responded more to the arid conditions that have been going on for several years.
“The hydrological conditions of these rivers, which meet the criteria of hydrological drought, are observed from the first ten days of July. Currently, the hydrological situation in the Nemunas is the worst in the last 4 years – since 2017, which were extremely rainy, there has been a decrease in water levels, “LHMT said in the report.
In the first ten days of August, the prevailing hot and dry weather significantly depleted the water bodies. As water levels continue to decline, more and more rivers are reaching their environmental flow (that is, the minimum water flow necessary to guarantee the minimum living conditions of the ecosystem).
The environmental protection flow is currently monitored in Nemunas near Druskininkai, Nemajūnai, Kaunas and Smalinininkai, in Lėvenis near Bernatoniai, in Neris near Vilnius, in Šalčiai near Valkininkai, in Ūla near Zervynas.
“Since the locations for the water stations are selected so that fluctuations in the water level describe the largest possible area, it can be said that the sediment in these basins and other rivers can reach the environmental flow,” said the Service. Hydrometeorological in a statement.
The dry weather will persist for the next few days, so the water content of all rivers will change little.
