The Qom River or Qom Roud (Persian: رودخانه قمرود) is a large river in Iran that receives its water from the Zagros Mountains and mounds into the Namak Lake.[1] The Qom River flows through the city of Qom, and together with the Qareh Su it gains a length of approximately 400 km (250 mi).[2] The water level fluctuates greatly, between 312 m³/s and only 4 m³/s. This is partially the effect of the use of the Qom water for irrigation.
In 2014, the World Resources Institute ranked the Qom basin as "extremely high" for water stress.[3]
