It rises at the southern slopes of the Medvednica near {{ill|Sesvetska Sela|hr}}, and flows towards the southeast, passing through the eponymous village of {{ill|Črnec Dugoselski|hr}}. Afterwards its flow has been modified by humans and it reaches the Lonja near Posavski Bregi through the canal that connects it with the Sava.
