Ha Noi is formed from the Red River Delta, geographically characterized as a "City of rivers and lakes" or "City inside rivers". Thanks to the large and small rivers flowing tirelessly through over thousands of years that bring fertile to the land. Currently, there are 7 rivers running through Ha Noi including Red, Duong, Da, Nhue, Cau, Day and Ca Lo Rivers.

In particular, Red River section running through Ha Noi is up to 163km (representing 1/3 of the length of the river flowing through the territory of Viet Nam). In the inner city, beside the two rivers - To Lich and Kim Nguu - there is also a system of lakes and marshes acting as the drainage path of Ha Noi.

In the last century, there were over 100 large and small lakes, most of which were natural lagoon pools, the remains of former river sections, some were artificial lakes transformed from boggy fields into lakes. At present, although the majorities were leveled for construction, there remain hundreds of large and small lakes and marshes distributed across wards and communes of the capital of Ha Noi. The most famous ones are Hoan Kiem Lake, West Lake, Quang Ba, Truc Bach, Thien Quang, Bay Mau, Thanh Nhan, Linh Dam, Yen So, Giang Vo, Dong Mo, Suoi Hai, etc.

These lakes of Ha Noi are not only huge water reservoirs but also a natural air conditioning system reducing the heat in the inner city coming from blocks of concrete, steel, asphalt and the operation of plants, etc. Ha Noi's lakes not only create a cool climate for the city - an urban microclimate - but are also famous beauty spots, unique cultural areas of Thang Long – Ha Noi.
