Nine rivulets flow into the lake, and it drains into the Haliacmon river. Its depth varies from nine to ten metres. The Kastoria Peninsula (with the town of Kastoria) divides the lake into two parts, the larger to the north and the smaller to the south.

The lake takes its name from the Oreiades. Lakeside attractions include, apart from the Byzantine architectural heritage of the town, an 11th-century Byzantine monastery of Panagia Mavriotissa and the reconstructed prehistoric settlement of Dispilio, where the Dispilio Tablet was retrieved from the lake in 1992. The lake is known to freeze in winters.
