... and even in winter almost warm enough for swimming ;-)Excerpt from the wiki to the river Erft:
Due to the warm water discharge from the lignite industry into the Erft, entrained plant species such as the Brazilian Thousand Leaf and the South American leaved Waterpest can survive here. Every year, 300 million cubic meters of heated groundwater ("sump water") are pumped from the lignite mining into the Erft. Added to this is the cooling water from the lignite-fired power plant Frimmersdorf. In winter the mean water temperatures are still 15 ° C and in summer 28 ° C. The middle reaches of the river is 8 ° C warmer than the upper reaches. The hot water is supplied below Erftstadt. Already in the 1990s, anglers reported the three-time catch of piranhas, which in contrast to the sunfish could not form a reproductive population, but were only exposed aquarium fish and probably survived only a few months. Also found in the Erft guppies and red-eared turtles. For this reason, the BUND tried to stop the construction of the lignite power plant Neurath.Source: de.wikipedia.org/wiki/Erft
