The Nam Van Lake (Chinese: 南灣湖; Portuguese: Lago Nam Van) is a man-made lake in Sé, Macau. It is one of two man made lakes in Macau. It is located at the southern end of Macau Peninsula.
The lake was once part of a bay (Praia Grande Bay), created when the causeway (Avenida Dr Sun Yat Sen) partially closed off the bay. The project to close the lake began in 1991 to attract more development in Macau.[1]Nam Van means South Bay in Chinese.
Much of the land southwest of the bay was created from landfill.
