List of rivers of Bulgaria

This is a list of rivers in Bulgaria, organised geographically, taken clockwise from the westernmost tributaries of the Danube drainage.

This system includes the entire Danubian Plain and a stretch of land running 48–80 km inland from the coastline in the south.

The river's highest water levels usually occur during the May floods; it is frozen over an average of 40 days per year.

It passes through Sofia's eastern suburbs and crosses the Balkan Mountains through a spectacular 65 km–long gorge.

[1] Other important tributaries of the Danube include the rivers Lom, Ogosta, Vit, Osam and Yantra.

[4] The Aegean Sea catchment basin drains the Thracian Plain and most of the higher lands to the south and southwest.
