[1] The lake is situated in the lower reaches of the river Krka, and it covers an area of 11.1 square kilometres (4.3 sq mi).

[1] Despite its connection to the sea, it does not have high salinity: in the lower layers its water is salty, and near the surface it is freshwater.

The lake's major tributary is the Krka River, which has its source near the border with Bosnia and Herzegovina, flows through Knin and enters Prokljansko jezero near the city of Skradin.

In the northern part of the lake, there is a small islet called Stipanac, a site with ruins dating from antiquity to medieval times.

Another very popular tourist destination is Krka National Park, situated some fifteen kilometers from Skradin, which attracts about 700,000 visitors every year.
