It is 3 km long and up to 700 m wide, reaching a depth of 30 m, and is situated 15 km southeast of the capital city of Sofia, where the Vitoshka Bistritsa flows into the Iskar.
The villages of Pancharevo and Kokalyane and the Pancharevo mineral springs and National rowing canal "Sredets" lies on the lake's western shore, while at the southern end of the lake there is a hydroelectric power station. Sports centres and catering establishments have been constructed around the lake, making it a favoured outing location for the residents of Sofia.
