The snowfall over the past weekend significantly increased the water reserves in the snow in the Morava basin. The current state of water reserves in the snow in Moravia below the confluence with the Dyjí is 491 million cubic meters, the amount of snow in the Morava basin has thus increased sixfold in a few days.
Therefore, water managers are draining some water reservoirs as a precaution, as it is expected to warm up in the coming days. Petr Chmelař, the spokesman for the state enterprise Povodí Moravy, informed about this in a press release today.
The level of most water reservoirs is reduced due to this year’s drought and lack of rainfall. Povodí Morava is currently freeing up storage space on other reservoirs. The water level is going down in Plumlov, Mostiště, Výrovice, Jevišovice, Boskovice and Bystřička. The goal is to release approximately 30 percent of the water supply.
“It is a preventive measure. Warming should occur in the coming days, and we will carefully monitor how much water soaks into the ground and how much flows into rivers and streams. We regularly evaluate the situation and manipulate it according to the current situation. At the same time, we must make sure that we do not lower the water level too much, so that there is enough water for waterworks, industry and other purposes,” described the General Director of Povodí Moravy Václav Gargulák.
In recent years, the snow cover even at lower altitudes has been rather exceptional. However, its water resources are important for replenishing surface and underground water. “The current situation is not fundamentally exceptional, it’s just that we’ve gotten used to a similar situation in recent years due to climate change,” added Gargulák.
