Thousands of fish die in Dyje River due to heat and low oxygen levels

Thousands of fish have perished in the Dyje River in the Břeclav region due to high temperatures and low oxygen levels in the water. While some of the dead fish have already surfaced, many remain at the riverbed and are expected to float up in the coming days, according to local fishermen engaged in a clean-up operation. Water management authorities began increasing the outflow from the Nové Mlýny reservoirs over the weekend so as to aerate the water. However due to the extreme weather conditions, the situation could worsen in other areas. Similar die-offs occurred in 2018 and again three years ago, causing damages worth millions of crowns.
