Who was the Chola king who brought Ganga from North to South?

After defeating the Pala kingdom, King Rajendra Chola came back south, bringing with him water from the Ganges. He built a new city and called it ‘Gangaikonda Cholapuram’ – The city of the Chola who brought the Ganges. He built a Shiva temple in the city, rivaling the one his father built in Thanjavur. He built a 22 km wide artificial lake near the city. He shifted the Chola capital from Thanjavur.
