(2,382)
Althäuser Lake (max. depth 17 meters) is located right next a local dive center that has created several entry and exit points. You can enter / exit via the aluminum stairs or from the jetty by rolling backwards, using a giant stride entry forward, or the boat ladder.
You will see sturgeons, carp, perch, pike, eels, catfish, mussels, crabs, and, from July to September, freshwater jellyfish.
