The Cottbus East Lake belongs to the city of Cottbus and, to the north, to the Spree-Neiße district.

It is a residual lake from the Cottbus-Nord open-cast lignite mine, which was active until 2015.

The lake was filled with water from the Spree River between 2019 and 2024, and its maximum depth is 30 meters.

We circumnavigated the Baltic Sea accompanied by @Cornell Paasche, @Reni and Kerstin LB. Reni came to us by chance because she actually wanted to do the Baltic Sea the day before and Cornell invited her to join us on our tour - and that was a good thing. It just worked and the mood was good despite the sometimes dreary …

In the bike lane - on foot, of course - at the car park near the Merzdorf observation tower on the Baltic Sea. …

May 11, 2024,ILC – BRB 08: Cottbuser Ostsee

8/10: #ironlakechallenge Brandenburg - the last open-cast mining lake on my list. The Cottbus Baltic Sea is still about 1.2m away from reaching its target water level. And you can see everywhere that this is still a work in progress. But I found the lake and the tour all the cooler. Because there are still lots of corners where you …

Starting at the observation tower, Stadthafen 1, we walked around the lake. Good walkable paths and reasonably good weather without rain were the companions. Finally, we went to the lookout tower, from which you have a beautiful view of the Baltic Sea and Cottbus.
