Rivers
Mahavali Rever (Ganga) is the largest of the 103 river basins
found in Sri Lanka. It covers about 16% of the island's total
area. The river itself has a winding course, rising about
50 km south of Kandy and flowing north then north-east to
the sea near Trincomalee covering a distance of 320 km. It
is the only perennial river to cross the dry Zone. Sri Lanka’s
all perenial revers are called Ganga,while seasonal streams
are called Oya in Sinhala or Aru in Tamil. A number of rivers
have now been developed both for irrigation and power. The
Victoria project on Mahavali Ganga is one of the largest in
Asia.
