In addition to these, the municipalities by the lake include Lempäälä in the Pirkanmaa region and Hattula and Janakkala in the Tavastia Proper region.
The lake is connected to Mallasvesi in the north, which itself is the joining point of two chains of lakes; The Längelmävesi route in the northeast, consisting of the lakes Längelmävesi, Vesijärvi, Roine, and Pälkänevesi.
