Heat becomes a danger for living beings in the Main

In Hesse, the summer temperatures for the fish in the Main soon become a problem. As the Darmstadt regional council announced yesterday, the persistently warm weather means there is a risk that the temperature in the river will rise to a critical 25 degrees. Due to the high water temperature, the Main’s ability to absorb oxygen is significantly reduced, it said.

The municipal and industrial water dischargers were asked to exhaust all possibilities when reaching the critical 25 degrees to keep the pollution of the discharged wastewater as low as possible so that as few nutrients as possible get into the water, explained a spokesman for the regional council. The aim is to keep the oxygen enrichment in the body of water as high as possible until the weather conditions change.

According to the Hessian State Agency for Nature Conservation, Environment and Geology (HLNUG), the water temperature of the Main has already risen above the 25 degree mark in some places: In Frankfurter Osthafen 25 degrees were measured this morning at 5 a.m., yesterday evening the temperature was already 25.5 degrees. An overview of the current water temperatures can be found here on the interactive map of the HLNUG.
