Regensburg (dpa/lby) - Due to the somewhat cooler daytime temperatures, the living conditions for animals and plants in the Danube have improved somewhat. The government of the Upper Palatinate therefore lifted a warning for water ecology between Regensburg and Passau that had been issued last week. The Danube alarm plan had been downgraded to an advance warning, the authority reported on Tuesday.
Due to the warm and associated low-oxygen water, fish and other creatures have been endangered in a number of Bavarian rivers in the past few weeks, and authorities have sometimes reported fish deaths. A water temperature of 27 degrees was measured on the Danube at the Pfelling measuring point in Lower Bavaria on Friday, which is too warm. But now the water temperature is significantly lower again.
According to the district government, the situation has eased somewhat due to the easing of the hot days, maximum temperatures below 30 degrees and cooler nights. "The oxygen content of the water is over 7 milligrams per liter in the early morning hours, which means good conditions for the aquatic organisms." However, the development will continue to be monitored.
The emergency plan for the Danube has been in force since 2020. It should help to preserve the ecological quality of the river. "The aim of the various warning levels is to use precautionary measures to keep the burden on the aquatic organisms in the Danube as low as possible," explained the authority.
