With the Persian Shah's approval, Yusuf Khan diverted the main river to drive out the hostiles and built the Soltan Abad fortress, or Baladeh, a war fortress to act as a buffer and serve as the foundation of what would become modern Arak.
It flows through the Alborz mountain range, generally eastward, past the town of Baladeh into the Haraz River.
