The lake has an elevation of 57.4 metres (188ft) and a surface area of 5.2 square kilometres (2.0sqmi).
The navigable River Havel flows through the Woblitzsee, entering via a channel from the Großer Labussee. The river exits the lake at Wesenburg via a 7.2 kilometres (4.5mi) channel to the Wangnitzsee. The Kammer Canal also connects to the Woblitzsee, allowing vessels to reach the Zierker See and Neustrelitz. The lake is navigable between these three entrances, and navigation is administered as part of the Obere–Havel–Wasserstraße.
